fe8e81b7e8 adp5061: New driver for ADP5061 I2C battery charger
This patch adds basic support for Analog Devices I2C programmable linear
battery charger.

With this driver, some parameters can be read and configured such as:
* trickle charge current level (PRECHARGE_CURRENT)
* trickle charge voltage threshold (VOLTAGE_MIN)
* weak charge threshold (VOLTAGE_AVG)
* constant current (CONSTANT_CHARGE_CURRENT)
* constant charge voltage limit (CONSTANT_CHARGE_VOLTAGE_MAX)
* battery full (CAPACITY_LEVEL)
* input current limit (INPUT_CURRENT_LIMIT)
* charger status (STATUS)
* battery status (CAPACITY_LEVEL)
* termination current (CHARGE_TERM_CURRENT)

74421786f0 platform/x86: Rename silead_dmi to touchscreen_dmi
Not only silead touchscreens need some extra info not available in the
ACPI tables to work properly. X86 devices with a Chipone ICN8505 chip also
need some DMI based extra configuration.

There is no reason to have separate dmi config code per touchscreen
controller vendor. This commit renames silead_dmi to a more generic
touchscreen_dmi name (and Kconfig option) in preparation of adding
info for tablets with an ICN8505 based touchscreen.

Note there are no functional changes all code changes are limited to
removing references to silead where these are no longer applicable.

9a69f5087c drivers/staging: Gasket driver framework + Apex driver
The Gasket (Google ASIC Software, Kernel Extensions, and Tools) kernel
framework is a generic, flexible system that supports thin kernel
drivers. Gasket kernel drivers are expected to handle opening and
closing devices, mmap'ing BAR space as requested, a small selection of
ioctls, and handling page table translation (covered below). Any other
functions should be handled by userspace code.

The Gasket common module is not enough to run a device. In order to
customize the Gasket code for a given piece of hardware, a device
specific module must be created. At a minimum, this module must define a
struct gasket_driver_desc containing the device-specific data for use by
the framework; in addition, the module must declare an __init function
that calls gasket_register_device with the module's gasket_driver_desc
struct. Finally, the driver must define an exit function that calls
gasket_unregister_device with the module's gasket_driver_desc struct.

One of the core assumptions of the Gasket framework is that precisely
one process is allowed to have an open write handle to the device node
at any given time. (That process may, once it has one write handle, open
any number of additional write handles.) This is accomplished by
tracking open and close data for each driver instance.

Add a "type" device attribute and a "GNSS_TYPE" uevent variable which
can be used to determine the type of a GNSS receiver. The currently
identified types reflect the protocol(s) supported by a receiver:

	"NMEA"	NMEA 0183
	"SiRF"	SiRF Binary
	"UBX"	UBX

Note that both SiRF and UBX type receivers typically support a subset of
NMEA 0183 with vendor extensions (e.g. to allow switching to the vendor
protocol).

2b6a440351 gnss: add GNSS receiver subsystem
Add a new subsystem for GNSS (e.g. GPS) receivers.

While GNSS receivers are typically accessed using a UART interface they
often also support other I/O interfaces such as I2C, SPI and USB, while
yet other devices use iomem or even some form of remote-processor
messaging (rpmsg).

The new GNSS subsystem abstracts the underlying interface and provides a
new "gnss" class type, which exposes a character-device interface (e.g.
/dev/gnss0) to user space. This allows GNSS receivers to have a
representation in the Linux device model, something which is important
not least for power management purposes.

Note that the character-device interface provides raw access to whatever
protocol the receiver is (currently) using, such as NMEA 0183, UBX or
SiRF Binary. These protocols are expected to be continued to be handled
by user space for the time being, even if some hybrid solutions are also
conceivable (e.g. to have kernel drivers issue management commands).

This will still allow for better platform integration by allowing GNSS
devices and their resources (e.g. regulators and enable-gpios) to be
described by firmware and managed by kernel drivers rather than
platform-specific scripts and services.

While the current interface is kept minimal, it could be extended using
IOCTLs, sysfs or uevents as needs and proper abstraction levels are
identified and determined (e.g. for device and feature identification).

Pull ARM SoC fixes from Olof Johansson:
 "A handful of fixes, nothing really concerning and most touching
  devicetree files for various platforms.

  I also regenerated the shared multiplatform defconfigs; they have
  drifted quite a bit due to Kconfig changes and reordering, and several
  platform maintainers tried doing the same which resulted in a lot of
  conflict pain -- this way we get everybody onto the same base for next
  merge window"

f62252bf39 First set of IIO new device support, features and cleanups in the 4.19 cycle
The usual mixed bunch.  Particular good to see is the generic
 touch screen driver.  Will be interesting to see if this works
 for other ADCs without major changes.
 
 Core features
 * Channel types
   - New position relative channel type primarily for touch screen
     sensors to feed the generic touchscreen driver.
 
 New device support
 * ad5586
   - Add support for the AD5311R DAC.
 
 * Generic touch screen driver as an IIO consumer.
   - Note this is in input, but due to dependencies is coming through
     the IIO tree.
   - Specific support for this added to the at91-sama5d2 ADC.
   - Various necessary DT bindings added.
 
 Staging Drops
 * ADIS16060 gyro
   - A device with a very odd interface that was never cleanly supported.
     It's now very difficult to get, so unlikely it'll ever be fixed up.
 
 Cleanups and minor features and fixes
 * core
   - Fix y2038 timestamp issues now the core support is in place.
 * 104-quad-8
   - Provide some defines for magic numbers to help readability.
   - Fix an off by one error in register selection
 * ad7606
   - Put in a missing function parameter name in a prototype.
 * adis16023
   - Use generic sign_extend function rather than local version.
 * adis16240
   - Use generic sign_extend funciton rather than local version.
 * at91-sama5d2
   - Drop dependency on HAS_DMA now this is handled elsewhere.  Will
     improve build test coverage.
   - Add oversampling ratio control.  Note there is a minor ABI change
     here to increase the apparent depth to 14 bits so as to allow
     for transparent provision of different oversampling ratios that
     drop the actual bit depth to 13 or 12 bits.
 * hx711
   - Add a MAINTAINERS entry for this device.
 * inv_mpu6050
   - Replace the timestamp fifo 'special' code with generic timestamp
     handling.
   - Switch to using local store of timestamp divider rather than rate
     as that is more helpful for accurate time measurement.
   - Fix an unaligned access that didn't seem to be causing any trouble.
   - Use the fifo overflow bit to track the overflow status rather than
     a software counter.
   - New timestamping mechanism to deal with missed sample interrupts.
 * stm32-adc
   - Drop HAS_DMA build dependency.
 * sun4i-gpadc
   - Select REGMAP_IRQ a very rarely hit build issue fix.

   - Make Xen PV guest deal with speculative store bypass correctly

   - Address more fallout from the 5-Level pagetable handling. Undo an

     when post init code would touch the freed variable.

   - Handle exception fixup in math_error() before calling notify_die().
     The reverse call order incorrectly triggers notify_die() listeners
     for soemthing which is handled correctly at the site which issues
     the floating point instruction.

   - Fix an off by one in the LLC topology calculation on AMD

   - Handle non standard memory block sizes gracefully un UV platforms

0eb71a9da5 rhashtable: split rhashtable.h
Due to the use of rhashtables in net namespaces,
rhashtable.h is included in lots of the kernel,
so a small changes can required a large recompilation.
This makes development painful.

This patch splits out rhashtable-types.h which just includes
the major type declarations, and does not include (non-trivial)
inline code.  rhashtable.h is no longer included by anything
in the include/ directory.
Common include files only include rhashtable-types.h so a large
recompilation is only triggered when that changes.

6a4d4b3253 RISC-V Updates for the 4.18 Merge Window
This tag contains some small RISC-V updates I'd like to target for 4.18.
 They are all fairly small this time.  Here's a short summary, there's
 more info in the commits/merges.
 
 * A fix to __clear_user to respect the passed arguments.
 * Enough support for the perf subsystem to work with RISC-V's ISA
   defined performance counters.
 * Support for sparse and cleanups suggested by it.
 * Support for R_RISCV_32 (a relocation, not the 32-bit ISA).
 * Some MAINTAINERS cleanups.
 * The addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always
   present.
 
 I've given these a simple build+boot test.

cf65a0f6f6 dma-mapping: move all DMA mapping code to kernel/dma
Currently the code is split over various files with dma- prefixes in the
lib/ and drives/base directories, and the number of files keeps growing.
Move them into a single directory to keep the code together and remove
the file name prefixes.  To match the irq infrastructure this directory
is placed under the kernel/ directory.

8efcf34a26 ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or
 took a while longer for us to review and merge than usual and thus cut
 it a bit close to the merge window. We stage them in a separate branch
 and if things look good, we still send them up -- and that's the case
 here.
 
 This is mostly DT additions for Renesas platforms, adding IP block
 descriptions for existing and new SoCs.
 
 There are also some driver updates for Qualcomm platforms for SMEM/QMI
 and GENI, which is their generalized serial protocol interface.

7c00e8ae04 ARM: SoC platform updates
Here are the main updates for SoC support (besides DT additions) for ARM
 32- and 64-bit platforms. The branch also contains defconfig updates to
 turn on drivers and options as needed on the various platforms.
 
 The largest parts of the delta are from cleanups moving platform data
 and board file setup of TI platforms to ti-sysc bus drivers. There are
 also some sweeping changes of eeprom and nand setup on Davinci, i.MX
 and other platforms.
 
 Samsung is removing support for Exynos5440, which was an oddball SoC
 that hasn't been seen much use in designs.
 
 Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).
 
 Linus Walleij is also removing support for ux500 (Sony Ericsson)
 U8540/9540 SoCs that never made it to significant mass production and
 products.

5f85942c2e SCSI misc on 20180610
This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
 xfcp, hisi_sas, cxlflash, qla2xxx.  In the absence of Nic, we're also
 taking target updates which are mostly minor except for the tcmu
 refactor. The only real core change to worry about is the removal of
 high page bouncing (in sas, storvsc and iscsi).  This has been well
 tested and no problems have shown up so far.

6419945e33 This time we have a good set of changes to the core framework that do some
general cleanups, but nothing too major. The majority of the diff goes to
 two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for
 Actions Semi so it takes up some lines to add all the different types, and
 the Qualcomm diff is there because we add support for two SoCs and it's quite
 a bit of data.
 
 Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And
 then the long tail of driver updates for various fixes and stuff follows
 after that.
 
 Core:
  - debugfs cleanups removing error checking and an unused provider API
  - Removal of a clk init typedef that isn't used
  - Usage of match_string() to simplify parent string name matching
  - OF clk helpers moved to their own file (linux/of_clk.h)
  - Make clk warnings more readable across kernel versions
 
 New Drivers:
  - Qualcomm SDM845 GCC and Video clk controllers
  - Qualcomm MSM8998 GCC
  - Actions Semi S900 SoC support
  - Nuvoton npcm750 microcontroller clks
  - Amlogic axg AO clock controller
 
 Removed Drivers:
  - Deprecated Rockchip clk-gate driver
 
 Updates:
  - debugfs functions stopped checking return values
  - Support for the MSIOF module clocks on Rensas R-Car M3-N
  - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
  - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
  - Berlin and Amlogic SPDX tagging
  - Usage of of_clk_get_parent_count() in more places
  - Proper implementation of the CDEV1/2 clocks on Tegra20
  - Allwinner H6 PRCM clock support and R40 EMAC support
  - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet
  - Round closest support for meson's mpll driver
  - Support for meson8b nand clocks and gxbb video decoder clocks
  - Mediatek mali clks
  - STM32MP1 fixes
  - Uniphier LD11/LD20 stream demux system clock

eafdca4d70 Staging/IIO patches for 4.18-rc1
Here is the big staging and IIO driver update for 4.18-rc1.
 
 It was delayed as I wanted to make sure the final driver deletions did
 not cause any major merge issues, and all now looks good.
 
 There are a lot of patches here, just over 1000.  The diffstat summary
 shows the major changes here:
 	1007 files changed, 16828 insertions(+), 227770 deletions(-)
 Because of this, we might be close to shrinking the overall kernel
 source code size for two releases in a row.
 
 There was loads of work in this release cycle, primarily:
 	- tons of ks7010 driver cleanups
 	- lots of mt7621 driver fixes and cleanups
 	- most driver cleanups
 	- wilc1000 fixes and cleanups
 	- lots and lots of IIO driver cleanups and new additions
 	- debugfs cleanups for all staging drivers
 	- lots of other staging driver cleanups and fixes, the shortlog
 	  has the full details.
 
 but the big user-visable things here are the removal of 3 chunks of
 code:
 	- ncpfs and ipx were removed on schedule, no one has cared about
 	  this code since it moved to staging last year, and if it needs
 	  to come back, it can be reverted.
 	- lustre file system is removed.  I've ranted at the lustre
 	  developers about once a year for the past 5 years, with no
 	  real forward progress at all to clean things up and get the
 	  code into the "real" part of the kernel.  Given that the
 	  lustre developers continue to work on an external tree and try
 	  to port those changes to the in-kernel tree every once in a
 	  while, this whole thing really really is not working out at
 	  all.  So I'm deleting it so that the developers can spend the
 	  time working in their out-of-tree location and get things
 	  cleaned up properly to get merged into the tree correctly at a
 	  later date.
 
 Because of these file removals, you will have merge issues on some of
 these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
 atomisp driver).  Just delete those files, it's a simple merge :)
 
 All of this has been in linux-next for a while with no reported
 problems.

68cc38ff33 regulator: Updates for v4.18
Quite a lot of core work this time around, though not 100% successful.
 
 We gained support for runtime mode changes thanks to David Collins and
 improved support for write only regulators (ones where we can't read
 back the configuration) from Douglas Anderson.
 
 There's been quite a bit of work from Linus Walleij on converting from
 specfying GPIOs by numbers to descriptors.  Sadly the testing turned out
 to be less good than we had hoped and so a lot of this had to be
 reverted.
 
 We also have the start of updates to use coupled regulators from Maciej
 Purski, unfortunately there are further problems there so the last
 couple of patches have been reverted.
 
 We also have new drivers for BD71837 and SY8106A devices, SAW regulators
 on Qualcomm SPMI and dropped support for some preproduction chips
 that never made it to market from the AB8500 driver.

omapfb is not maintained by me anymore, so drop my name from the
maintainers, and mark omapfb as orphan.

At some point in the future we should mark omapfb as obsolete, but there
are still some features supported by omapfb which are not supported by
omapdrm, so we're not there yet.

6e0832fa43 PCI: Collect all native drivers under drivers/pci/controller/
Native PCI drivers for root complex devices were originally all in
drivers/pci/host/.  Some of these devices can also be operated in endpoint
mode.  Drivers for endpoint mode didn't seem to fit in the "host"
directory, so we put both the root complex and endpoint drivers in
per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc.

These per-device directories contain trivial Kconfig and Makefiles and
clutter drivers/pci/.  Make a new drivers/pci/controllers/ directory and
collect all the device-specific drivers there.

No functional change intended.

edb2a385ec This is the bulk of pin control changes for v4.18.
No core changes this time! Just a calm all-over-the-place
 drivers, updates and fixes cycle as it seems.
 
 New drivers/subdrivers:
 
 - Actions Semiconductor S900 driver with more Actions
   variants for S700, S500 in the pipe. Also generic GPIO
   support on top of the same driver and IRQ support is in
   the pipe.
 
 - Renesas r8a77470 PFC support.
 
 - Renesas r8a77990 PFC support.
 
 - Allwinner Sunxi H6 R_PIO support.
 
 - Rockchip PX30 support.
 
 - Meson Meson8m2 support.
 
 - Remove support for the ill-fated Samsung Exynos 5440 SoC.
 
 Improvements:
 
 - Context save/restore support in pinctrl-single.
 
 - External interrupt support for the Mediatek MT7622.
 
 - Qualcomm ACPI HID QCOM8002 supported.
 
 Fixes:
 
 - Fix up suspend/resume support for Exynos 5433.
 
 - Fix Strago DMI fixes on the Intel Cherryview.

Linus Torvalds
ca95bf62fc linux-kselftest-4.18-rc1
This Kselftest update for 4.18-rc1 consists of:
 
 - Work to restructure timers test suite to move PIE out of rtctest from
   Alexandre Belloni.
 
 - Several minor spelling and bug fixes.
 
 - New cgroup tests from Roman Gushchin and Mike Rapoport.
 
 - Kselftest framework changes to handle and report skipped tests correctly.
   Prior to these changes, framework treated all non-zero return codes from
   tests as failures. When tests are skipped with non-zero return code, due
   to unmet dependencies and/or unsupported configuration, reporting them as
   failed lead to false negatives on the tests that couldn't be run.
 
 - Fixes to test Makefiles to remove unnecessary RUN_TESTS and EMIT_TESTS
   overrides and use common defines from lib.mk.
 
 - Fixes to several tests to return correct Kselftest skip code.
 
 - Changes to improve test output.

0ad39cb3d7 Kconfig updates for v4.18
Kconfig now supports new functionality to perform textual substitution.
 It has been a while since Linus suggested to move compiler option tests
 from makefiles to Kconfig. Finally, here it is. The implementation has
 been generalized into a Make-like macro language. Some built-in functions
 such as 'shell' are provided. Variables and user-defined functions are
 also supported so that 'cc-option', 'ld-option', etc. are implemented as
 macros.
 
 Summary:
 
 - refactor package checks for building {m,n,q,g}conf
 
 - remove unused/unmaintained localization support
 
 - remove Kbuild cache
 
 - drop CONFIG_CROSS_COMPILE support
 
 - replace 'option env=' with direct variable expansion
 
 - add built-in functions such as 'shell'
 
 - support variables and user-defined functions
 
 - add helper macros as as 'cc-option'
 
 - add unit tests and a document of the new macro language
 
 - add 'testconfig' to help
 
 - fix warnings from GCC 8.1

   the control device is now registered at last
 - PCM locking code cleanups for RT kernels
 - Fixes for possible races in ALSA timer resolution accesses
 - TLV offset definitions in uapi
 
 ASoC:
 - Many fixes for the topology stuff, including fixes for v4 ABI
   compatibility
 - Lots of cleanups / quirks for Intel platforms based on Realtek
   CODECs
 - Continued componentization works, removing legacy CODEC stuff
 - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver
 - Fixes and updates to Cirrus Logic SoC drivers
 - New Qualcomm DSP support

Expose a new system call allowing each thread to register one userspace
memory area to be used as an ABI between kernel and user-space for two
purposes: user-space restartable sequences and quick access to read the
current CPU number value from user-space.

* Restartable sequences (per-cpu atomics)

Restartables sequences allow user-space to perform update operations on
per-cpu data without requiring heavy-weight atomic operations.

The restartable critical sections (percpu atomics) work has been started
by Paul Turner and Andrew Hunter. It lets the kernel handle restart of
critical sections. [1] [2] The re-implementation proposed here brings a
few simplifications to the ABI which facilitates porting to other
architectures and speeds up the user-space fast path.

Here are benchmarks of various rseq use-cases.

Test hardware:

arm32: ARMv7 Processor rev 4 (v7l) "Cubietruck", 2-core
x86-64: Intel E5-2630 v3@2.40GHz, 16-core, hyperthreading

The following benchmarks were all performed on a single thread.

* Per-CPU statistic counter increment

                getcpu+atomic (ns/op)    rseq (ns/op)    speedup
arm32:                344.0                 31.4          11.0
x86-64:                15.3                  2.0           7.7

* LTTng-UST: write event 32-bit header, 32-bit payload into tracer
             per-cpu buffer

                getcpu+atomic (ns/op)    rseq (ns/op)    speedup
arm32:               2502.0                 2250.0         1.1
x86-64:               117.4                   98.0         1.2

* liburcu percpu: lock-unlock pair, dereference, read/compare word

                getcpu+atomic (ns/op)    rseq (ns/op)    speedup
arm32:                751.0                 128.5          5.8
x86-64:                53.4                  28.6          1.9

* jemalloc memory allocator adapted to use rseq

Using rseq with per-cpu memory pools in jemalloc at Facebook (based on
rseq 2016 implementation):

The production workload response-time has 1-2% gain avg. latency, and
the P99 overall latency drops by 2-3%.

* Reading the current CPU number

Speeding up reading the current CPU number on which the caller thread is
running is done by keeping the current CPU number up do date within the
cpu_id field of the memory area registered by the thread. This is done
by making scheduler preemption set the TIF_NOTIFY_RESUME flag on the
current thread. Upon return to user-space, a notify-resume handler
updates the current CPU value within the registered user-space memory
area. User-space can then read the current CPU number directly from
memory.

Keeping the current cpu id in a memory area shared between kernel and
user-space is an improvement over current mechanisms available to read
the current CPU number, which has the following benefits over
alternative approaches:

- 35x speedup on ARM vs system call through glibc
- 20x speedup on x86 compared to calling glibc, which calls vdso
  executing a "lsl" instruction,
- 14x speedup on x86 compared to inlined "lsl" instruction,
- Unlike vdso approaches, this cpu_id value can be read from an inline
  assembly, which makes it a useful building block for restartable
  sequences.
- The approach of reading the cpu id through memory mapping shared
  between kernel and user-space is portable (e.g. ARM), which is not the
  case for the lsl-based x86 vdso.

On x86, yet another possible approach would be to use the gs segment
selector to point to user-space per-cpu data. This approach performs
similarly to the cpu id cache, but it has two disadvantages: it is
not portable, and it is incompatible with existing applications already
using the gs segment selector for other purposes.

Benchmarking various approaches for reading the current CPU number:

ARMv7 Processor rev 4 (v7l)
Machine model: Cubietruck
- Baseline (empty loop):                                    8.4 ns
- Read CPU from rseq cpu_id:                               16.7 ns
- Read CPU from rseq cpu_id (lazy register):               19.8 ns
- glibc 2.19-0ubuntu6.6 getcpu:                           301.8 ns
- getcpu system call:                                     234.9 ns

x86-64 Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz:
- Baseline (empty loop):                                    0.8 ns
- Read CPU from rseq cpu_id:                                0.8 ns
- Read CPU from rseq cpu_id (lazy register):                0.8 ns
- Read using gs segment selector:                           0.8 ns
- "lsl" inline assembly:                                   13.0 ns
- glibc 2.19-0ubuntu6 getcpu:                              16.6 ns
- getcpu system call:                                      53.9 ns

- Speed (benchmark taken on v8 of patchset)

Running 10 runs of hackbench -l 100000 seems to indicate, contrary to
expectations, that enabling CONFIG_RSEQ slightly accelerates the
scheduler:

Configuration: 2 sockets * 8-core Intel(R) Xeon(R) CPU E5-2630 v3 @
2.40GHz (directly on hardware, hyperthreading disabled in BIOS, energy
saving disabled in BIOS, turboboost disabled in BIOS, cpuidle.off=1
kernel parameter), with a Linux v4.6 defconfig+localyesconfig,
restartable sequences series applied.

* CONFIG_RSEQ=n

avg.:      41.37 s
std.dev.:   0.36 s

* CONFIG_RSEQ=y

avg.:      40.46 s
std.dev.:   0.33 s

- Size

On x86-64, between CONFIG_RSEQ=n/y, the text size increase of vmlinux is
567 bytes, and the data size increase of vmlinux is 5696 bytes.

be65f9ed26 staging: lustre: delete the filesystem from the tree.
The Lustre filesystem has been in the kernel tree for over 5 years now.
While it has been an endless source of enjoyment for new kernel
developers learning how to do basic codingstyle cleanups, as well as an
semi-entertaining source of bewilderment from the vfs developers any
time they have looked into the codebase to try to figure out how to port
their latest api changes to this filesystem, it has not really moved
forward into the "this is in shape to get out of staging" despite many
half-completed attempts.

And getting code out of staging is the main goal of that portion of the
kernel tree.  Code should not stagnate and it feels like having this
code in staging is only causing the development cycle of the filesystem
to take longer than it should.  There is a whole separate out-of-tree
copy of this codebase where the developers work on it, and then random
changes are thrown over the wall at staging at some later point in time.
This dual-tree development model has never worked, and the state of this
codebase is proof of that.

So, let's just delete the whole mess.  Now the lustre developers can go
off and work in their out-of-tree codebase and not have to worry about
providing valid changelog entries and breaking their patches up into
logical pieces.  They can take the time they have spend doing those
types of housekeeping chores and get the codebase into a much better
shape, and it can be submitted for inclusion into the real part of the
kernel tree when ready.

fd129f8941 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Daniel Borkmann says:

====================
pull-request: bpf-next 2018-06-05

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add a new BPF hook for sendmsg similar to existing hooks for bind and
   connect: "This allows to override source IP (including the case when it's
   set via cmsg(3)) and destination IP:port for unconnected UDP (slow path).
   TCP and connected UDP (fast path) are not affected. This makes UDP support
   complete, that is, connected UDP is handled by connect hooks, unconnected
   by sendmsg ones.", from Andrey.

2) Rework of the AF_XDP API to allow extending it in future for type writer
   model if necessary. In this mode a memory window is passed to hardware
   and multiple frames might be filled into that window instead of just one
   that is the case in the current fixed frame-size model. With the new
   changes made this can be supported without having to add a new descriptor
   format. Also, core bits for the zero-copy support for AF_XDP have been
   merged as agreed upon, where i40e bits will be routed via Jeff later on.
   Various improvements to documentation and sample programs included as
   well, all from Björn and Magnus.

3) Given BPF's flexibility, a new program type has been added to implement
   infrared decoders. Quote: "The kernel IR decoders support the most
   widely used IR protocols, but there are many protocols which are not
   supported. [...] There is a 'long tail' of unsupported IR protocols,
   for which lircd is need to decode the IR. IR encoding is done in such
   a way that some simple circuit can decode it; therefore, BPF is ideal.
   [...] user-space can define a decoder in BPF, attach it to the rc
   device through the lirc chardev.", from Sean.

4) Several improvements and fixes to BPF core, among others, dumping map
   and prog IDs into fdinfo which is a straight forward way to correlate
   BPF objects used by applications, removing an indirect call and therefore
   retpoline in all map lookup/update/delete calls by invoking the callback
   directly for 64 bit archs, adding a new bpf_skb_cgroup_id() BPF helper
   for tc BPF programs to have an efficient way of looking up cgroup v2 id
   for policy or other use cases. Fixes to make sure we zero tunnel/xfrm
   state that hasn't been filled, to allow context access wrt pt_regs in
   32 bit archs for tracing, and last but not least various test cases
   for fixes that landed in bpf earlier, from Daniel.

5) Get rid of the ndo_xdp_flush API and extend the ndo_xdp_xmit with
   a XDP_XMIT_FLUSH flag instead which allows to avoid one indirect
   call as flushing is now merged directly into ndo_xdp_xmit(), from Jesper.

6) Add a new bpf_get_current_cgroup_id() helper that can be used in
   tracing to retrieve the cgroup id from the current process in order
   to allow for e.g. aggregation of container-level events, from Yonghong.

7) Two follow-up fixes for BTF to reject invalid input values and
   related to that also two test cases for BPF kselftests, from Martin.

8) Various API improvements to the bpf_fib_lookup() helper, that is,
   dropping MPLS bits which are not fully hashed out yet, rejecting
   invalid helper flags, returning error for unsupported address
   families as well as renaming flowlabel to flowinfo, from David.

9) Various fixes and improvements to sockmap BPF kselftests in particular
   in proper error detection and data verification, from Prashant.

10) Two arm32 BPF JIT improvements. One is to fix imm range check with
    regards to whether immediate fits into 24 bits, and a naming cleanup
    to get functions related to rsh handling consistent to those handling
    lsh, from Wang.

11) Two compile warning fixes in BPF, one for BTF and a false positive
    to silent gcc in stack_map_get_build_id_offset(), from Arnd.

12) Add missing seg6.h header into tools include infrastructure in order
    to fix compilation of BPF kselftests, from Mathieu.

13) Several formatting cleanups in the BPF UAPI helper description that
    also fix an error during rst2man compilation, from Quentin.

14) Hide an unused variable in sk_msg_convert_ctx_access() when IPv6 is
    not built into the kernel, from Yue.

15) Remove a useless double assignment in dev_map_enqueue(), from Colin.

These include a significant update of the generic power domains (genpd)
 and Operating Performance Points (OPP) frameworks, mostly related to
 the introduction of power domain performance levels, cpufreq updates
 (new driver for Qualcomm Kryo processors, updates of the existing
 drivers, some core fixes, schedutil governor improvements), PCI power
 management fixes, ACPI workaround for EC-based wakeup events handling
 on resume from suspend-to-idle, and major updates of the turbostat
 and pm-graph utilities.
 
 Specifics:
 
  - Introduce power domain performance levels into the the generic
    power domains (genpd) and Operating Performance Points (OPP)
    frameworks (Viresh Kumar, Rajendra Nayak, Dan Carpenter).
 
  - Fix two issues in the runtime PM framework related to the
    initialization and removal of devices using device links (Ulf
    Hansson).
 
  - Clean up the initialization of drivers for devices in PM domains
    (Ulf Hansson, Geert Uytterhoeven).
 
  - Fix a cpufreq core issue related to the policy sysfs interface
    causing CPU online to fail for CPUs sharing one cpufreq policy in
    some situations (Tao Wang).
 
  - Make it possible to use platform-specific suspend/resume hooks
    in the cpufreq-dt driver and make the Armada 37xx DVFS use that
    feature (Viresh Kumar, Miquel Raynal).

aca429ff9d gpio: madera: Support Cirrus Logic Madera class codecs
This adds support for the GPIOs on Cirrus Logic Madera class codecs.
Any pins not used for special functions (see the pinctrl driver) can be
used as general single-bit input or output lines. The number of available
GPIOs varies between codecs.

Note that this is part of a composite MFD for these codecs and can only
be used with the corresponding MFD and other child drivers on those
silicon. The GPIO block on these codecs does not exist indepedently of
the rest of the MFD.

218d72a77b pinctrl: madera: Add driver for Cirrus Logic Madera codecs
These codecs have a variable number of I/O lines each of which
is individually selectable to a wide range of possible functions.

The functionality is slightly different from the traditional muxed
GPIO since most of the functions can be mapped to any pin (and even
the same function to multiple pins). Most pins have a dedicated
"alternate" function that is only available on that pin. The
alternate functions are usually a group of signals, though it is
not always necessary to enable the full group, depending on the
alternate function and how it is to be used. The mapping between
alternate functions and GPIO pins varies between codecs depending
on the number of alternate functions and available pins.

These are complex audio codec SoCs with a variety of digital and analogue

97c2b5cba2 mfd: madera: Add register definitions for Cirrus Logic Madera codecs
This patch adds a header file of register definitions for Cirrus
Logic "Madera" class codecs. These codecs are all based off a common
set of hardware IP so have a common register map (with a few minor
device-to-device variations).

The registers.h file is tool-generated directly from the hardware design
but has been manually stripped down to reduce size (full register
map is >44000 lines). All names are kept the same as datasheet names
so that they can be cross-referenced between source and datasheet without
confusion.

The register map layout is kept fully-defined rather than factored into
macros and/or block-indexing code. The major reasons for this are:

 - #1 is that it makes the source highly greppable, which is important.
   "What does the driver do with register bits XYZ" or "Where does it use
   register bits XYZ" are commonly types of questions. These can be quickly
   answered by a grep. Squashing definitions into generator macros or block-
   indexing code is a way of defeating grep.

 - most of the register definitions are used in tables, so a constant value
   is required. Using generator macros make the table definition clunky and
   obscure.

 - the code is clearer when it's there in the source exactly what register
   and field it is using

 - it is easier to diff the register map of a new (unsupported) codec against
   what is already supported and merge in differences

 - it makes the register map available in source for maintenance/debugging
   instead of having to refer back to the datasheet for a register map

   Notable changes beyond an overall update in the tooling itself is the

 - qspinlock improvements: the locking algorithm now guarantees forward
   progress whereas the previous implementation in mainline could starve

Intel Wired LAN Driver Updates 2018-06-04

This series contains a smorgasbord of updates to documentation, e1000e,
igb, ixgbe, ixgbevf and i40e.

Benjamin Poirier fixes a potential kernel crash due to NULL pointer
dereference in e1000e.

Jeff updates the kernel documentation for e100 and e1000 to correct
default values and URLs which were incorrect in the documentation.  Also
took the time to update these to the new reStructured text format for
kernel documentation.

Joanna Yurdal fixes a missing PTP transmit timestamp by ensuring that
TSICR gets cleared when ICR is cleared.

Sergey updates igb to reset all the transmit queues at one time so that
we only have to wait once for all the queues to be reset.

Alex fixes ixgbevf so that malicious driver detection (MDD) can co-exist
with XDP.

Emil and Tony extend the RTNL lock to ensure we get the most up-to-date
values for the bits and avoid a possible race condition when going down.

YueHaibing from Huawei introduces a helper function in ixgbe for
operation reads to simplify the code a bit more.

Daniel Borkmann adds support for XDP meta data when using build SKB
for i40e.

Shannon Nelson provides twp fixes for the IPSec code in ixgbe, first is
to make sure we do not try to offload the decryption of any incoming
packet that is destined for the management engine.  The other fix is to
resolve a cast problem introduced by a sparse cleanup patch.

MAINTAINERS: Add myself as a maintainer for SiFive's drivers
There aren't actually any files in the tree that match these patterns
right now, but we've just started submitting our drivers so I thought it
would be good to make sure there's at least someone at SiFive who's
listed as maintaining them.  I'm leaving the RISC-V lists on here
because:

* As of today, all the RISC-V ASICs that people can actually buy are
  from SiFive -- though hopefully there'll be more soon!
* The RTL for many of our devices is open source, so I anticipate these
  devices might make they way chips from other vendors.
* We may standardize some of these devices as part of a RISC-V
  specification at some point in the future.

I'm a bit swamped right now so I might not be the most active maintainer
of these drivers, but I think it'd be good to make sure someone who has
hardware access gets CC'd on updates to our drivers just as a sanity
check.  Hopefully that's an OK way to handle this.

46e2856b8e cpufreq: Add Kryo CPU scaling driver
In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors,
the CPU frequency subset and voltage value of each OPP varies
based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables
defines the voltage and frequency value based on the msm-id in SMEM
and speedbin blown in the efuse combination.
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

cfc80d9a11 net: Introduce net_failover driver
The net_failover driver provides an automated failover mechanism via APIs
to create and destroy a failover master netdev and manages a primary and
standby slave netdevs that get registered via the generic failover
infrastructure.

The failover netdev acts a master device and controls 2 slave devices. The
original paravirtual interface gets registered as 'standby' slave netdev and
a passthru/vf device with the same MAC gets registered as 'primary' slave
netdev. Both 'standby' and 'failover' netdevs are associated with the same
'pci' device. The user accesses the network interface via 'failover' netdev.
The 'failover' netdev chooses 'primary' netdev as default for transmits when
it is available with link up and running.

This can be used by paravirtual drivers to enable an alternate low latency
datapath. It also enables hypervisor controlled live migration of a VM with
direct attached VF by failing over to the paravirtual datapath when the VF
is unplugged.

30c8bd5aa8 net: Introduce generic failover module
The failover module provides a generic interface for paravirtual drivers
to register a netdev and a set of ops with a failover instance. The ops
are used as event handlers that get called to handle netdev register/
unregister/link change/name change events on slave pci ethernet devices
with the same mac address as the failover netdev.

This enables paravirtual drivers to use a VF as an accelerated low latency
datapath. It also allows migration of VMs with direct attached VFs by
failing over to the paravirtual datapath when the VF is unplugged.

316d55d55f Documentation: kconfig: document a new Kconfig macro language
Add a document for the macro language introduced to Kconfig.

The motivation of this work is to move the compiler option tests to
Kconfig from Makefile.  A number of kernel features require the
compiler support.  Enabling such features blindly in Kconfig ends up
with a lot of nasty build-time testing in Makefiles.  If a chosen
feature turns out unsupported by the compiler, what the build system
can do is either to disable it (silently!) or to forcibly break the
build, despite Kconfig has let the user to enable it.  By moving the
compiler capability tests to Kconfig, features unsupported by the
compiler will be hidden automatically.

This change was strongly prompted by Linus Torvalds.  You can find
his suggestions [1] [2] in ML.  The original idea was to add a new
attribute with 'option shell=...', but I found more generalized text
expansion would make Kconfig more powerful and lovely.  The basic
ideas are from Make, but there are some differences.

S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.

TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.

The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.

Overlapping changes in __sock_map_ctx_update_elem(), keep the bits

782e6769c0 dma-mapping: provide a generic dma-noncoherent implementation
Add a new dma_map_ops implementation that uses dma-direct for the
address mapping of streaming mappings, and which requires arch-specific
implemenations of coherent allocate/free.

Architectures have to provide flushing helpers to ownership trasnfers
to the device and/or CPU, and can provide optional implementations of
the coherent mmap functionality, and the cache_flush routines for
non-coherent long term allocations.

The Cadence CSI-2 RX Controller is an hardware block meant to be used as a
bridge between a CSI-2 bus and pixel grabbers.

It supports operating with internal or external D-PHY, with up to 4 lanes,
or without any D-PHY. The current code only supports the latter case.

It also support dynamic mapping of the CSI-2 virtual channels to the
associated pixel grabbers, but that isn't allowed at the moment either.

0eca353e7a misc: IBM Virtual Management Channel Driver (VMC)
This driver is a logical device which provides an
interface between the hypervisor and a management
partition. This interface is like a message
passing interface. This management partition
is intended to provide an alternative to HMC-based
system management.

VMC enables the Management LPAR to provide basic
logical partition functions:
- Logical Partition Configuration
- Boot, start, and stop actions for individual
  partitions
- Display of partition status
- Management of virtual Ethernet
- Management of virtual Storage
- Basic system management

This driver is to be used for the POWER Virtual
Management Channel Virtual Adapter on the PowerPC
platform. It provides a character device which
allows for both request/response and async message
support through the /dev/ibmvmc node.

The bpf syscall and selftests conflicts were trivial
overlapping changes.

The r8169 change involved moving the added mdelay from 'net' into a
different function.

A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts.  I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

6a8b25abf1 1st round of IIO new device support, features and cleanup for the 4.18 cycle
A nice mix this time of excellent cleanups (many to send drivers
 speeding toward staging graduations) and new drivers / device support.
 A good part of this is Brian Masney's never ending task on the tsl2x7x
 driver.  The end is in sight so hopefully we'll get that one out of
 staging very soon!
 
 New device support
 * AD5686
   - Support AD5685R (was wrongly present as AD5685)
   - Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
     SPI DACs with various precisions.
   - Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
     I2C DACs with various percisions and numbers of channels.
 * Analog front end rescale driver - New driver.
   - Support current sensing usings a shunt resistor.
   - Support simple voltage dividers.
   - support simple current sense amplifiers.
 * TI dac5571
   - New driver and device bindings supporting:
     dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
     dac5573, dac6573 and dac7573
 * Meson-adc
   - Support for Meson AXG with DT bindings.
 * mpu6050
   - Support the mpu9255 which only requires additional WHOAMI entry and
     compatible string.
 * st_lsm6dsx
   - Support for lsm330dlc combinded accelerometer and gyro sensors with
     DT bindings.
 * stm32_adc
   - Add support for STM32MP1 with bindings.
 
 Staging graduations
 * adis16201 after some excelent cleanup by Himanshu Jha.
 * adis16029 after some excelent cleanup by Shreeya Patel.
 
 New features:
 * ABI docs
   - Add core ABI docs for angle channels.
 * inv_mpu6050
   - Provide support for the full range of interrupts the device
     supports.
 * st_accel
   - Add SMO8840 ACPI ID seen in the wild on some Lenovo machines.
 * stx104
   - Provide a multiple gpio get function.
 
 Cleanups / Minor fixes
 * core
   - Use new nested structure support to improve kernel-doc.
 * ad2s1200
   - Use be16_to_cpup instead of opencoding.
 * ad5686
   - Indentation tidy up.
   - Switch to SPDX
   - Refactor to allow various numbers of channels.
   - Refactor to separate core and SPI specific support, prior to
     addition of i2c equivalent devices.
 * ad7606
   - Use drvdata directly from device rather than boucing via the
     platform_device structure.
 * ad7746
   - Replace opencoded byte swapped i2c calls with _swapped variants.
   - White space and line break readability improvements.
   - Reorder includes and variable declarations where appropriate.
 * ad7791
   - Changes to the AD ADC library used by this driver took in the
     sampling frequency.  This lead to be the wrong path being the one
     tied to the resulting attribute, so it didn't work, and a warning
     to be printed.
 * ad7780
   - Remove apparent support for sampling frequency control on devices
     that don't support changing the sampling attributes.
 * ade7854
   - Fix a read of the wrong number of bits.
   - Improve error handling on i2c read/write errors.
   - Rework i2c and spi code to reduce duplication.
 * adis16201 (staging)
   - Improve meaning inherent in some macro names by adding units etc
     where relevant.
   - Adjust comments to improve detail and drop the irrelevant.
   - Rename register address definitions definitions to add a _REG
     postfix, clearly separating them from field definitions. Reorganize
     the definitions to group register address and fields.
   - Use sign_extend32 rather than open coding.
   - Reverse Xmas tree ordering where appropriate and align function args.
   - Remove unused headers.
   - Use GENMASK where appropriate instead of open coding.
 * adis16209 (staging)
   - Indent field definitions to visually separate them from
     register address definitions.
   - Use reverse xmas tree ordering where appropriate.
   - Add some whitespace where it will help readability.
   - Drop some unused headers.
   - Use GENMASK where appropriate.
 * ad2s1200
   - Drop unnecessary includes and reorder alphabetically.
   - Reverse xmas tree and blank line cleanups.
 * atlas-ph-sensor
   - Use msleep instead of usleep_range where the precise value doesn't
     matter and the delays are long.
 * bcm150
   - Drop transaction splitting as core now handles it.
 * cros_ec
   - Move the shared header to the include/iio/common directory.
     This brings it inline with the other multiple type devices.
   - Use drvdata directly from device rather than boucing via the
     platform_device structure.
 * hid-sensors
   - Use drvdata directly from device rather than boucing via the
     platform_device structure.
 * inv_mpu6050
   - Clear out a second function definition for the same function.
   - Don't flush fifo when the iio buffer is full but just drop excess

Merge tag 'iio-for-4.18a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

1st round of IIO new device support, features and cleanup for the 4.18 cycle

A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.
A good part of this is Brian Masney's never ending task on the tsl2x7x
driver.  The end is in sight so hopefully we'll get that one out of
staging very soon!

New device support
* AD5686
  - Support AD5685R (was wrongly present as AD5685)
  - Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
    SPI DACs with various precisions.
  - Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
    I2C DACs with various percisions and numbers of channels.
* Analog front end rescale driver - New driver.
  - Support current sensing usings a shunt resistor.
  - Support simple voltage dividers.
  - support simple current sense amplifiers.
* TI dac5571
  - New driver and device bindings supporting:
    dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
    dac5573, dac6573 and dac7573
* Meson-adc
  - Support for Meson AXG with DT bindings.
* mpu6050
  - Support the mpu9255 which only requires additional WHOAMI entry and
    compatible string.
* st_lsm6dsx
  - Support for lsm330dlc combinded accelerometer and gyro sensors with
    DT bindings.
* stm32_adc
  - Add support for STM32MP1 with bindings.

Staging graduations
* adis16201 after some excelent cleanup by Himanshu Jha.
* adis16029 after some excelent cleanup by Shreeya Patel.

New features:
* ABI docs
  - Add core ABI docs for angle channels.
* inv_mpu6050
  - Provide support for the full range of interrupts the device
    supports.
* st_accel
  - Add SMO8840 ACPI ID seen in the wild on some Lenovo machines.
* stx104
  - Provide a multiple gpio get function.

Cleanups / Minor fixes
* core
  - Use new nested structure support to improve kernel-doc.
* ad2s1200
  - Use be16_to_cpup instead of opencoding.
* ad5686
  - Indentation tidy up.
  - Switch to SPDX
  - Refactor to allow various numbers of channels.
  - Refactor to separate core and SPI specific support, prior to
    addition of i2c equivalent devices.
* ad7606
  - Use drvdata directly from device rather than boucing via the
    platform_device structure.
* ad7746
  - Replace opencoded byte swapped i2c calls with _swapped variants.
  - White space and line break readability improvements.
  - Reorder includes and variable declarations where appropriate.
* ad7791
  - Changes to the AD ADC library used by this driver took in the
    sampling frequency.  This lead to be the wrong path being the one
    tied to the resulting attribute, so it didn't work, and a warning
    to be printed.
* ad7780
  - Remove apparent support for sampling frequency control on devices
    that don't support changing the sampling attributes.
* ade7854
  - Fix a read of the wrong number of bits.
  - Improve error handling on i2c read/write errors.
  - Rework i2c and spi code to reduce duplication.
* adis16201 (staging)
  - Improve meaning inherent in some macro names by adding units etc
    where relevant.
  - Adjust comments to improve detail and drop the irrelevant.
  - Rename register address definitions definitions to add a _REG
    postfix, clearly separating them from field definitions. Reorganize
    the definitions to group register address and fields.
  - Use sign_extend32 rather than open coding.
  - Reverse Xmas tree ordering where appropriate and align function args.
  - Remove unused headers.
  - Use GENMASK where appropriate instead of open coding.
* adis16209 (staging)
  - Indent field definitions to visually separate them from
    register address definitions.
  - Use reverse xmas tree ordering where appropriate.
  - Add some whitespace where it will help readability.
  - Drop some unused headers.
  - Use GENMASK where appropriate.
* ad2s1200
  - Drop unnecessary includes and reorder alphabetically.
  - Reverse xmas tree and blank line cleanups.
* atlas-ph-sensor
  - Use msleep instead of usleep_range where the precise value doesn't
    matter and the delays are long.
* bcm150
  - Drop transaction splitting as core now handles it.
* cros_ec
  - Move the shared header to the include/iio/common directory.
    This brings it inline with the other multiple type devices.
  - Use drvdata directly from device rather than boucing via the
    platform_device structure.
* hid-sensors
  - Use drvdata directly from device rather than boucing via the
    platform_device structure.
* inv_mpu6050
  - Clear out a second function definition for the same function.
  - Don't flush fifo when the iio buffer is full but just drop excess
    data.
  - Tidy up set_power_itg and ensure it is used in the right places.
  - Use set_power_itg rather than opencoding it again in the i2c mux
    control.

e7330fa032 Input: add support for ChipOne icn8505 based touchscreens
The ChipOne icn8505 is an i2c capacitive touchscreen controller typically
used in cheap x86 tablets, this commit adds a driver for it.

Note the icn8505 is somewhat similar to the icn8318 and I started with
modifying that driver to support both, but in the end the differences were
too large and I decided to write a new driver instead.

2ff0e41ac5 MAINTAINERS: add keyword for devicetree overlay notifiers
Devicetree overlay notifiers have a chance to potentially get
pointers into the overlay unflattened devicetree and overlay FDT.
The only protection against these pointers being accessed after
the underlying data has been released by kfree() is by source
code review of patches.  Add a keyword line to the devicetree
overlay maintainers entry to try to catch overlay notifier
related patches.

The keyword line is added to the devicetree overlay entry instead
of the devicetree entry so that not all maintainers will receive
the additional review traffic.  Add Frank Rowand (already a
maintainer in the devicetree entry) so that he will receive
the additional review traffic.

From now on, I'll start using my @kernel.org as my development e-mail.

As such, let's remove the entries that point to the old
mchehab@s-opensource.com at MAINTAINERS file.

For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.

For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.

For bug reports, we can simply point to just kernel.org, as
this will reach my mchehab+samsung inbox anyway.

57692c94dc drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+
This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.

V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme.  This massively changes the
GEM behavior, so I've forked off to a new driver.

v2: Mark SUBMIT_CL as needing DRM_AUTH.  coccinelle fixes from kbuild
    test robot. Drop personal git link from MAINTAINERS.  Don't
    double-map dma-buf imported BOs.  Add kerneldoc about needing MMU
    eviction.  Drop prime vmap/unmap stubs.  Delay mmap offset setup
    to mmap time.  Use drm_dev_init instead of _alloc.  Use
    ktime_get() for wait_bo timeouts.  Drop drm_can_sleep() usage,
    since we don't modeset.  Switch page tables back to WC (debug
    change to coherent had slipped in).  Switch
    drm_gem_object_unreference_unlocked() to
    drm_gem_object_put_unlocked().  Simplify overflow mem handling by
    not sharing overflow mem between jobs.
v3: no changes
v4: align submit_cl to 64 bits (review by airlied), check zero flags in
    other ioctls.

4d220ed0f8 bpf: remove tracepoints from bpf core
tracepoints to bpf core were added as a way to provide introspection
to bpf programs and maps, but after some time it became clear that
this approach is inadequate, so prog_id, map_id and corresponding
get_next_id, get_fd_by_id, get_info_by_fd, prog_query APIs were
introduced and fully adopted by bpftool and other applications.
The tracepoints in bpf core started to rot and causing syzbot warnings:
WARNING: CPU: 0 PID: 3008 at kernel/trace/trace_event_perf.c:274
Kernel panic - not syncing: panic_on_warn set ...
perf_trace_bpf_map_keyval+0x260/0xbd0 include/trace/events/bpf.h:228

map_update_elem kernel/bpf/syscall.c:597 [inline]
SYSC_bpf kernel/bpf/syscall.c:1478 [inline]
Hence this patch deletes tracepoints in bpf core.

8b74816b5a iio: afe: rescale: new driver
If an ADC channel measures the midpoint of a voltage divider, the
interesting voltage is often the voltage over the full resistance.
E.g. if the full voltage is too big for the ADC to handle.
Likewise, if an ADC channel measures the voltage across a shunt
resistor, with or without amplification, the interesting value is
often the current through the resistor.

This driver solves these problems by allowing to linearly scale a channel
and/or by allowing changes to the type of the channel.

 Some vboxguest fixes for systems with lots of memory, amba bus fixes,
 some MAINTAINERS updates, uio_hv_generic driver fixes, and a few other
 minor things that resolve problems that people reported.
 
 The amba bus fixes took twice to get right, the first time I messed up
 applying the patches in the wrong order, hence the revert and later
 addition again with the correct fix, sorry about that.
 
 All of these have been in linux-next with no reported issues.
