71f5c63c07 phy: exynos-mipi-video: Add support for Exynos 5420 and 5433 SoCs
This patch adds support for MIPI DPHYs found in Exynos5420-compatible
(5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from
earlier by different offset of MIPI DPHY registers in PMU controllers
(Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to
separate system register controllers (Exynos 5433 case). In both case
also additional 5th PHY (MIPI CSIS 2) has been added.

d3feb40673 phy: bcm-ns-usb2: new driver for USB 2.0 PHY on Northstar
Northstar is a family of SoCs used in home routers. They have USB 2.0
and 3.0 controllers with PHYs that need to be properly initialized.
This driver provides PHY init support in a generic way and can be bound
with an EHCI controller driver.
There are (just a few) registers being defined in bcma header. It's
because DMU/CRU registers will be also needed in other drivers. We will
need them e.g. in PCIe controller/PHY driver and at some point probably
in clock driver for BCM53573 chipset. By using include/linux/bcma/ we
avoid code duplication.

13541cc3d4 dt-bindings: pci: tegra: Update for per-lane PHYs
The XUSB pad controller allows PCIe lanes to be controlled individually,
providing fine-grained control over their power state. Previous attempts
at describing the XUSB pad controller in DT had erroneously assumed that
all PCIe lanes were driven by the same PHY, and hence the PCI host
controller would reference only a single PHY.

Moving to a representation of per-lane PHYs requires that the operating
system driver for the PCI host controller have access to the set of PHY
devices that make up the connection of each root port in order to power
up and down all of the lanes as necessary.

b1accd107b dt-bindings: phy: Add NVIDIA Tegra XUSB pad controller binding
The NVIDIA Tegra XUSB pad controller provides a set of pads, each with a
set of lanes that are used for PCIe, SATA and USB.

A binding exists for the XUSB pad controller already, but it turned out
not to be flexible enough to describe all aspects of the controller. In
particular, the addition of XUSB support (for SuperSpeed USB) has shown
that the existing binding is no longer suitable. Mark the old binding
as deprecated and link to the new binding.

cde7bc367f phy: rcar-gen3-usb2: add fallback binding
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

ce15bda101 usb: changes for v4.7 merge window
Here's the big USB Gadget pull request. This time
 not as large as usual with only 57 non-merge
 commits.
 
 The most important part here is, again, all the work
 on dwc3. This time around we're treating all
 endpoints (except for control endpoint) exactly the
 same. They all have the same amount of TRBs on the
 ring, they all treat the ring as an actual ring with
 a link TRB pointing to the head, etc.
 
 We're also helping the host side burst (on
 SuperSpeed GEN1 or GEN2 at least) for as long as
 possible until the endpoint returns NRDY.
 
 Other than this big TRB ring rework on dwc3, we also
 have a dwc3-omap DMA initialization fix, some extra
 debugfs files to aid in some odd debug sessions and
 a complete removal of our FIFO resizing logic.
 
 We have a new quirk for some dwc3 P3 quirk in some
 implementations.
 
 The rest is basically non-critical fixes and the
 usual cleanups.

This includes a few functional changes:
 * new representation of MIC, SIC1 and SIC2 interrupt controllers,
 * disabled by default SPI1, SPI2, SSP0 and SSP1 SPI controllers in
   shared lpc32xx.dtsi file,
 * added clock sources for SPI1 and SPI2,
 * set default clock rate of HCLK PLL to main osc rate multiplied by 16.
 
 Also there are some non-functional changes:
 * flatten board DTS files by exploiting device node labels,
 * add 'partitions' device node for NAND SLC / MTD OF,
 * correct Atmel vendor prefix to describe on board AT24 EEPROMs,
 * rename board DTS files by adding SoC name prefix.
 
 Since now DTS files of LPC32xx boards match "^lpc32[2345]0-" pattern.

It appears people are reading this document as a requirements list for
building hardware. This is not the intent of this document. Nor is it
particularly suited for this purpose.

The primary purpose of this document is our collective attempt to define
a set of primitives that (hopefully) allow us to write correct code on
the myriad of SMP platforms Linux supports.

Its a definite work in progress as our understanding of these platforms,
and memory ordering in general, progresses.

Nor does being mentioned in this document mean we think its a
particularly good idea; the data dependency barrier required by Alpha
being a prime example. Yes we have it, no you're insane to require it
when building new hardware.

For platforms which are controlled via remove node manager, enable _PPC by
default. These platforms are mostly categorized as enterprise server or
performance servers. These platforms needs to go through some
certifications tests, which tests control via _PPC.
The relative risk of enabling by default is  low as this is is less likely
that these systems have broken _PSS table.

9522a2ff9c cpufreq: intel_pstate: Enforce _PPC limits
Use ACPI _PPC notification to limit max P state driver will request.
ACPI _PPC change notification is sent by BIOS to limit max P state
in several cases:
- Reduce impact of platform thermal condition
- When Config TDP feature is used, a changed _PPC is sent to
follow TDP change
- Remote node managers in server want to control platform power
via baseboard management controller (BMC)

This change registers with ACPI processor performance lib so that
_PPC changes are notified to cpufreq core, which in turns will
result in call to .setpolicy() callback. Also the way _PSS
table identifies a turbo frequency is not compatible to max turbo
frequency in intel_pstate, so the very first entry in _PSS needs
to be adjusted.

This feature can be turned on by using kernel parameters:
intel_pstate=support_acpi_ppc

When jumping to the next attribute, only the length of the current

This last bug was not visible before commit 80df554275, because the

c5dfd78eb7 perf core: Allow setting up max frame stack depth via sysctl
The default remains 127, which is good for most cases, and not even hit
most of the time, but then for some cases, as reported by Brendan, 1024+
deep frames are appearing on the radar for things like groovy, ruby.

And in some workloads putting a _lower_ cap on this may make sense. One
that is per event still needs to be put in place tho.

The new file is:

  # cat /proc/sys/kernel/perf_event_max_stack
  127

Chaging it:

  # echo 256 > /proc/sys/kernel/perf_event_max_stack
  # cat /proc/sys/kernel/perf_event_max_stack
  256

But as soon as there is some event using callchains we get:

  # echo 512 > /proc/sys/kernel/perf_event_max_stack
  -bash: echo: write error: Device or resource busy
  #

Because we only allocate the callchain percpu data structures when there
is a user, which allows for changing the max easily, its just a matter
of having no callchain users at that point.

91ea692f87 Here are the latest bug fixes for ARM SoCs, mostly addressing
recent regressions. Changes are across several platforms, so
 I'm listing every change separately here.
 
 Regressions since 4.5:
 
  - A correction of the psci firmware DT binding, to prevent
    users from relying on unintended semantics
 
  - Actually getting the newly merged clock driver for some OMAP
    platforms to work
 
  - A revert of patches for the Qualcomm BAM, these need to be
    reworked for 4.7 to avoid breaking boards other than the one
    they were intended for
 
  - A correction for the I2C device nodes on the Socionext Uniphier
    platform
 
  - i.MX SDHCI was broken for non-DT platforms due to a change
    with the setting of the DMA mask
 
  - A revert of a patch that accidentally added a nonexisting
    clock on the Rensas "Porter" board
 
  - A couple of OMAP fixes that are all related to suspend after
    the power domain changes for dra7
 
  - On Mediatek, revert part of the power domain initialization
    changes that broke mt8173-evb
 
 Fixes for older bugs:
 
  - Workaround for an "external abort" in the omap34xx
    suspend/resume code.
 
  - The USB1/eSATA should not be listed as an excon device on
    am57xx-beagle-x15 (broken since v4.0)
 
  - A v4.5 regression in the TI AM33xx and AM43XX DT specifying
    incorrect DMA request lines for the GPMC
 
  - The jiffies calibration on Renesas platforms was incorrect
    for some modern CPU cores.
 
  - A hardware errata woraround for clockdomains on TI DRA7

5a45e01d41 2nd set of new device support, features and cleanup for IIO in the 4.7 cycle.
Bit of a bumper set for new drivers but plenty of other stuff here as well!
 
 New device support
 * ad5592R ADC/DAC
   - new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
 * Aosong am2315 relative humidity
   - new driver with triggered buffer support in follow up patch.
 * bmi160 imu
   - new driver
 * bmp280
   - bmp180 support - note there is support in the misc/bmp085 driver. Intent
     is to remove that driver long term.
 * invensense mpu6050
   - cleanup leading to explicit support of mpu9150 with a good few cleanups
     along the way.
 * Hope RF hp03 pressure and temperature sensor.
   - new driver
 * maxim DS1803 potentiometer
   - new driver
 * maxim max44000 light and proximity sensor
   - new driver built in a series of steps to support pretty much everything.
 * ROHM BH1780 light sensor
   - new driver. There is an existing driver in misc that this is pretty much
     intended to replace.  The discussion on whether to support the non standard
     interface of that driver is some way is continuing.
 * st-gyro
   - lsm9ds0-gyro.  The accel/magn side of this will take a while longer as
     extensions to the st library are needed for cases where two types of sensor
     share a single i2c address.
 * ti-adc081c
   - support the adc101c and adc121c
 * Vishay VEML6070 UV sensor
   - new driver.
 
 New features
 * core
   - devm_ APIs for channel_get and channel_get_all.  The first user of these
     is the generic ADC based thermal driver.  As it is going through the
     thermal tree these will be picked up as a patch to that next cycle as that
     is how the author preferred to do it.
   - mounting matrix support.  This new core support allows devices to provide
     to userspace (typically from the device tree) allowing compensation for how
     the sensor is mounted on the device.  First examples are on UAVs but it
     has a more mundane use on typical phone where the chip may be on the front
     or the back of the circuit board and soldered at any angle. Includes
     support for this ABI in ak8975 (which has an older interface, now
     deprecated) and mpu6050.
 * tools
   - add a -a option to enable all available channels in generic_buffer sample.
     Makes it somewhat easier to use.
 * adis library and drivers
   - support manual self test flag clearing.  This has technically been broken
     for a very long time - result is an offset on readings as the applied field
     is on all the time.
 * ak8975
   - triggered buffer support
 * bmc150
   - spi support (including splitting the driver into core and i2c parts)
 * bmp280
   - oversampling support.
 * dht11
   - improved logging - useful to debug timing issues on this quirky device.
 * st-sensors
   - read each channel invidivually as not all support the optimization of
   reading in bulk.  This is technically a fix, but will need to be backported
   if desired.
   - support open drain and shared interrupts.
 * ti-adc081c
   - triggered buffer support.
 
 Cleanups
 * inkern
   - white space fix.
 * ad7606
   - use the iio_device_claim_direct_mode call rather than open coding equiv.
 * ad799x
   - white space fix.
 * ad9523
   - unsigned -> unsigned int
 * apds9660
   - brace location tidying up.
   - silence an uninitialized variable warning.
 * ak8975
   - else and brace on same line fix.
 * at91_adc
   - white space fixes.
 * bmc150
   - use regmap stored copy of the device pointer rather than having an
     additional copy.
 * bmg160
   - use regmap stored copy of the device pointer rather than having an
     additional copy.
 * hid-sensors
   - white space fixes.
 * mcp3422
   - white space fix.
 * mma7455
   - use regmap to retrieve the device struct rather than carrying another copy
     in the private data.
 * ms_sensors
   - white space fix.
 * mxs-lradc
   - move current bindings out of staging - some will be shortly deprecated but
     the reality is that we have device trees out there using them so they will
     need to be supported for some time.  They accidentally got left behind
     when the driver graduated from staging.
   - white space cleanup.
   - set INPUT_PROP_DIRECT.
   - move ts config into a better function.
   - move the STMP reset out of the ADC init.
 * vf610_adc
   - case label indenting fix.

  - new driver. There is an existing driver in misc that this is pretty much
    intended to replace.  The discussion on whether to support the non standard
    interface of that driver is some way is continuing.
* st-gyro
  - lsm9ds0-gyro.  The accel/magn side of this will take a while longer as
    extensions to the st library are needed for cases where two types of sensor
    share a single i2c address.
* ti-adc081c
  - support the adc101c and adc121c
* Vishay VEML6070 UV sensor
  - new driver.

New features
* core
  - devm_ APIs for channel_get and channel_get_all.  The first user of these
    is the generic ADC based thermal driver.  As it is going through the
    thermal tree these will be picked up as a patch to that next cycle as that
    is how the author preferred to do it.
  - mounting matrix support.  This new core support allows devices to provide
    to userspace (typically from the device tree) allowing compensation for how
    the sensor is mounted on the device.  First examples are on UAVs but it
    has a more mundane use on typical phone where the chip may be on the front
    or the back of the circuit board and soldered at any angle. Includes
    support for this ABI in ak8975 (which has an older interface, now
    deprecated) and mpu6050.
* tools
  - add a -a option to enable all available channels in generic_buffer sample.
    Makes it somewhat easier to use.
* adis library and drivers
  - support manual self test flag clearing.  This has technically been broken
    for a very long time - result is an offset on readings as the applied field
    is on all the time.
* ak8975
  - triggered buffer support
* bmc150
  - spi support (including splitting the driver into core and i2c parts)
* bmp280
  - oversampling support.
* dht11
  - improved logging - useful to debug timing issues on this quirky device.
* st-sensors
  - read each channel invidivually as not all support the optimization of
  reading in bulk.  This is technically a fix, but will need to be backported
  if desired.
  - support open drain and shared interrupts.
* ti-adc081c
  - triggered buffer support.

Cleanups
* inkern
  - white space fix.
* ad7606
  - use the iio_device_claim_direct_mode call rather than open coding equiv.
* ad799x
  - white space fix.
* ad9523
  - unsigned -> unsigned int
* apds9660
  - brace location tidying up.
  - silence an uninitialized variable warning.
* ak8975
  - else and brace on same line fix.
* at91_adc
  - white space fixes.
* bmc150
  - use regmap stored copy of the device pointer rather than having an
    additional copy.
* bmg160
  - use regmap stored copy of the device pointer rather than having an
    additional copy.
* hid-sensors
  - white space fixes.
* mcp3422

* mma7455
  - use regmap to retrieve the device struct rather than carrying another copy
    in the private data.
* ms_sensors
  - white space fix.
* mxs-lradc
  - move current bindings out of staging - some will be shortly deprecated but
    the reality is that we have device trees out there using them so they will
    need to be supported for some time.  They accidentally got left behind
    when the driver graduated from staging.
  - white space cleanup.
  - set INPUT_PROP_DIRECT.
  - move ts config into a better function.
  - move the STMP reset out of the ADC init.
* vf610_adc
  - case label indenting fix.

6a1f547114 arm64: acpi: add acpi=on cmdline option to prefer ACPI boot over DT
If both ACPI and DT platform descriptions are available, and the
kernel was configured at build time to support both flavours, the
default policy is to prefer DT over ACPI, and preferring ACPI over
DT while still allowing DT as a fallback is not possible.

Since some enterprise features (such as RAS) depend on ACPI, it may
be desirable for, e.g., distro installers to prefer ACPI boot but
fall back to DT rather than failing completely if no ACPI tables are
available.

So introduce the 'acpi=on' kernel command line parameter for arm64,
which signifies that ACPI should be used if available, and DT should
only be used as a fallback.

978fa43623 drivers: firmware: psci: unify enable-method binding on ARM {64,32}-bit systems
Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.

However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.

This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".

So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

e705498945 cfg80211: Add option to report the bss entry in connect result
Since cfg80211 maintains separate BSS table entries for APs if the same
BSSID, SSID pair is seen on multiple channels, it is possible that it
can map the current_bss to a BSS entry on the wrong channel. This
current_bss will not get flushed unless disconnected and cfg80211
reports a wrong channel as the associated channel.

Fix this by introducing a new cfg80211_connect_bss() function which is
similar to cfg80211_connect_result(), but it includes an additional
parameter: the bss the STA is connected to. This allows drivers to
provide the exact bss entry that matches the BSS to which the connection
was completed.

Drop the 'experimental' annotations. The only remaining part of the API
that is still marked 'experimental' are the debug ioctls/structs, and
that is intentional. Only the v4l2-dbg application should use those.

All others have been around for years, so it is time to drop the
'experimental' designation.

Expose a rotation matrix to indicate userspace the chip placement with
respect to the overall hardware system. This is needed to adjust
coordinates sampled from a sensor chip when its position deviates from the
main hardware system.

Final coordinates computation is delegated to userspace since:
* computation may involve floating point arithmetics ;
* it allows an application to combine adjustments with arbitrary
  transformations.

This 3 dimentional space rotation matrix is expressed as 3x3 array of
strings to support floating point numbers. It may be retrieved from a
"[<dir>_][<type>_]mount_matrix" sysfs attribute file. It is declared into a
device / driver specific DTS property or platform data.

cee1afce30 sched/fair: Gather CPU load functions under a more conventional namespace
The CPU load update related functions have a weak naming convention
currently, starting with update_cpu_load_*() which isn't ideal as
"update" is a very generic concept.

Since two of these functions are public already (and a third is to come)
that's enough to introduce a more conventional naming scheme. So let's
do the following rename instead:

	update_cpu_load_*() -> cpu_load_update_*()

 Note that the "ARM: OMAP: Catch callers of revision information prior

 for other SoCs because omap initcalls bail out based on revision being
 set to 0 for other SoCs. These initcalls will mostly just disappear

e009a7e858 cxl: Allow initialization on timebase sync failures
Failure to synchronize the PSL timebase currently prevents the
initialization of the cxl card, thus rendering the card useless. This
is too extreme for a feature which is rarely used, if at all. No
hardware AFUs or software is currently using PSL timebase.

This patch still tries to synchronize the PSL timebase when the card
is initialized, but ignores the error if it can't. Instead, it reports
a status via /sys.

6d28f789bf KVM: s390: add clear I/O irq operation for FLIC
Introduce a FLIC operation for clearing I/O interrupts for a subchannel.

Rationale: According to the platform specification, pending I/O
interruption requests have to be revoked in certain situations. For
instance, according to the Principles of Operation (page 17-27), a
subchannel put into the installed parameters initialized state is in the
same state as after an I/O system reset (just parameters possibly changed).
This implies that any I/O interrupts for that subchannel are no longer
pending (as I/O system resets clear I/O interrupts). Therefore, we need an
interface to clear pending I/O interrupts.

Beside regular feed control interrupt, the driver requires also hash
interrupt for older SoCs (samsung,s5pv210-secss). However after
requesting it, the interrupt handler isn't doing anything with it, not
even clearing the hash interrupt bit.

Driver does not provide hash functions so it is safe to remove the hash
interrupt related code and to not require the interrupt in Device Tree.

a5fcec480f PCI: imx6: Add DT property for link gen, default to Gen1
Freescale has stated [1] that the LVDS clock source of the IMX6 does not
pass the PCI Gen2 clock jitter test, therefore unless an external Gen2
compliant external clock source is present and supplied back to the IMX6
PCIe core via LVDS CLK1/CLK2 you can not claim Gen2 compliance.

Add a DT property to specify Gen1 vs Gen2 and check this before allowing a
Gen2 link.

We default to Gen1 if the property is not present because at this time
there are no IMX6 boards in mainline that 'input' a clock on LVDS
CLK1/CLK2.

In order to be Gen2 compliant on IMX6 you need to:

 - Have a Gen2 compliant external clock generator and route that clock back
   to either LVDS CLK1 or LVDS CLK2 as an input (see IMX6SX-SabreSD
   reference design).

 - Specify this clock in the PCIe node in the DT (i.e.,
   IMX6QDL_CLK_LVDS1_IN or IMX6QDL_CLK_LVDS2_IN instead of
   IMX6QDL_CLK_LVDS1_GATE which configures it as a CLK output).

3ea8529acc PCI: imx6: Add reset-gpio-active-high boolean property to DT
Currently the reset-gpio DT property which controls the PCI bus device
reset signal defaults to active-low reset sequence (L=reset state,
H=operation state) plus the code in reset function isn't GPIO polarity
aware - it doesn't matter if the defined reset-gpio is active-low or
active-high, it will always result into active-low reset sequence.

I've tried to fix it properly and change the reset-gpio reset sequence to
be polarity-aware, but this patch has been accepted and then reverted as it
has introduced few backward incompatible issues:

1. Some DTBs, for example, imx6qdl-sabresd, don't define reset-gpio
polarity correctly:

  reset-gpio = <&gpio7 12 0>;

which means that it's defined as active-high, but in reality it's
active-low; thus it wouldn't work without a DTS fix.

2. The logic in the reset function is inverted:

	gpio_set_value_cansleep(imx6_pcie->reset_gpio, 0)
	msleep(100);
	gpio_set_value_cansleep(imx6_pcie->reset_gpio, 1);

so even if some of the i.MX6 boards had reset-gpio polarity defined
correctly in their DTSes, they would stop working.

As we can't break old DTBs, we can't fix them, so we need to introduce this
new DT reset-gpio-active-high boolean property so we can support boards
with active-high reset sequence.

This active-high reset sequence is for example needed on Apalis SoMs, where
GPIO1_IO28, used to PCIe reset is not connected directly to PERST# PCIe
signal, but it's ORed with RESETBMCU coming off the PMIC, and thus is
inverted, active-high.

4143804c4f clk: Add {devm_}clk_hw_{register,unregister}() APIs
We've largely split the clk consumer and provider APIs along
struct clk and struct clk_hw, but clk_register() still returns a
struct clk pointer for each struct clk_hw that's registered.
Eventually we'd like to only allocate struct clks when there's a
user, because struct clk is per-user now, so clk_register() needs
to change.

Let's add new APIs to register struct clk_hws, but this time
we'll hide the struct clk from the caller by returning an int
error code. Also add an unregistration API that takes the clk_hw
structure that was passed to the registration API. This way
provider drivers never have to deal with a struct clk pointer
unless they're using the clk consumer APIs.

5463bfda32 tracing: Add support for named hist triggers
Allow users to define 'named' hist triggers.  All triggers created
with the same 'name=xxx' option will update the same shared histogram
data.

This expands the hist trigger syntax from this:

    # echo hist:keys=xxx ... [ if filter] > event/trigger

to this:

    # echo hist:name=xxx:keys=xxx ... [ if filter] > event/trigger

Named histograms must use a 'compatible' set of keys and values, which
means each event added to a set of named triggers must have the same
names and types.

Reading the 'hist' file of any of the participating events will

If the line is set to be open drain, also tag on IRQF_SHARED
to the IRQ flags when requesting the interrupt, as the whole
point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).

5d8813271f ACPI / tables: Convert initrd table override to table upgrade mechanism
This patch converts the initrd table override mechanism to the table
upgrade mechanism by restricting its usage to the tables released with
compatibility and more recent revision.

This use case has been encouraged by the ACPI specification:

 1. OEMID:
    An OEM-supplied string that identifies the OEM.

 2. OEM Table ID:
    An OEM-supplied string that the OEM uses to identify the particular data
    table. This field is particularly useful when defining a definition
    block to distinguish definition block functions. OEM assigns each
    dissimilar table a new OEM Table Id.

 3. OEM Revision:
    An OEM-supplied revision number. Larger numbers are assumed to be newer
    revisions.

For OEMs, good practices will ensure consistency when assigning OEMID and
OEM Table ID fields in any table. The intent of these fields is to allow
for a binary control system that support services can use. Because many
support function can be automated, it is useful when a tool can
programatically determine which table release is a compatible and more
recent revision of a prior table on the same OEMID and OEM Table ID.

The facility can now be used by the vendors to upgrade wrong tables for bug
fixing purpose, thus lockdep disabling taint is not suitable for it and it
should be a default 'y' option to implement the spec encouraged use case.

Note that, by implementing table upgrade inside of ACPICA itself, it is
possible to remove acpi_table_initrd_override() and tables can be upgraded
by acpi_install_table() automatically. Though current ACPICA impelentation
hasn't implemented this, this patched changes the table flag setting timing
to allow this to be implemented in ACPICA without changing the code here.

Documentation of initrd override mechanism is upgraded accordingly.

ab98e20af5 This is first big chunk of Rockchip clock-related changes for 4.7.
Main change is probably the added support for the new rk3399 soc
 and necessary infrastructure changes surrounding it.
 
 The biggest chunk is probably that clock code is now able to
 handle multiple clock providers in one system, as the rk3399
 has two of those. A general one and another smaller one in a
 separate power domain. The rk3399 also uses another new pll type.
 Thankfully it just fits nicely into our current structure.
 It also needs some parts like the cpuclk mux parameters to be
 a bit more flexible and an new fractional divider subtype without
 gate.
 
 Apart from this big change we have some more fixes and removal
 of forgotten variables.

177e15f0c1 arm64: add the initrd region to the linear mapping explicitly
Instead of going out of our way to relocate the initrd if it turns out
to occupy memory that is not covered by the linear mapping, just add the
initrd to the linear mapping. This puts the burden on the bootloader to
pass initrd= and mem= options that are mutually consistent.

Note that, since the placement of the linear region in the PA space is
also dependent on the placement of the kernel Image, which may reside
anywhere in memory, we may still end up with a situation where the initrd
and the kernel Image are simply too far apart to be covered by the linear
region.

Since we now leave it up to the bootloader to pass the initrd in memory
that is guaranteed to be accessible by the kernel, add a mention of this to
the arm64 boot protocol specification as well.

bc5081617f usb: dwc3: drop FIFO resizing logic
That FIFO resizing logic was added to support OMAP5
ES1.0 which had a bogus default FIFO size. I can't
remember the exact size of default FIFO, but it was
less than one bulk superspeed packet (<1024) which
would prevent USB3 from ever working on OMAP5 ES1.0.

However, OMAP5 ES1.0 support has been dropped by
commit aa2f4b16f8 ("ARM: OMAP5: id: Remove ES1.0
support") which renders FIFO resizing unnecessary.

A lot display-controller nodes for DSI and the Analogix DP on rk3288
as well as general display+hdmi support on rk3036. With the Analogix
DP support, Veyron Chromeboks can now finally use their internal
display.

Other than this big improvement we have thermal support on the rk3228,
a long time missing binding document for the General Register Files
block, better operating points for Veyron devices and a bunch of fixes
with parts stemming from warnings that new dtc version can generate.

1d260123cb [media] soc_camera: rcar_vin: add device tree support for r8a7792
Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.

By documenting this compat string it may be used in DTSs shipped, for
example as part of ROMs. It must be used in conjunction with the Gen2
fallback compat string. At this time there are no known differences between
the r8a7792 IP block and that implemented by the driver for the Gen2
fallback compat string. Thus there is no need to update the driver as the
use of the Gen2 fallback compat string will activate the correct code in
the current driver while leaving the option for r8a7792-specific driver
code to be activated in an updated driver should the need arise.

bd546882ff [media] soc_camera: rcar_vin: add R-Car Gen 2 and 3 fallback compatibility strings
Add fallback compatibility string for R-Car Gen 1 and 2.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and 3. But beyond that it's unclear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

c422025c18 dmaengine: dw: rename masters to reflect actual topology
The source and destination masters are reflecting buses or their layers to
where the different devices can be connected. The patch changes the master
names to reflect which one is related to which independently on the transfer
direction.

The outcome of the change is that the memory data width is now always limited
by a data width of the master which is dedicated to communicate to memory.

The patch will not break anything since all current users have the same data
width for all masters. Though it would be nice to revisit avr32 platforms to
check what is the actual hardware topology in use there. It seems that it has
one bus and two masters on it as stated by Table 8-2, that's why everything
works independently on the master in use. The purpose of the sequential patch
is to fix the driver for configuration of more than one bus.

The change is done in the assumption that src_master and dst_master are
reflecting a connection to the memory and peripheral correspondently on avr32
and otherwise on the rest.

The emmc-phy is fully enclosed in the general register files (GRF).
Therefore as seen from the device-tree it shouldn't be a separate platform-

The driver entered the kernel in the current merge-window, so we can still
adapt the binding without needing a fallback, as the binding hasn't been
released with a full kernel yet.

following commit:

  2e4f5382d1 ("locking/doc: Rename LOCK/UNLOCK to ACQUIRE/RELEASE")

However, the commit missed to change the table of contents - fix that.

Also, the dumb rename changed the section name 'Locking functions' to an
actively misleading 'Acquiring functions' section name.

Rename it to 'Lock acquisition functions' instead.

ddbb411487 KEYS: Add KEYCTL_DH_COMPUTE command
This adds userspace access to Diffie-Hellman computations through a
new keyctl() syscall command to calculate shared secrets or public
keys using input parameters stored in the keyring.

Input key ids are provided in a struct due to the current 5-arg limit
for the keyctl syscall. Only user keys are supported in order to avoid
exposing the content of logon or encrypted keys.

The output is written to the provided buffer, based on the assumption
that the values are only needed in userspace.

Future support for other types of key derivation would involve a new
command, like KEYCTL_ECDH_COMPUTE.

Once Diffie-Hellman support is included in the crypto API, this code
can be converted to use the crypto API to take advantage of possible
hardware acceleration and reduce redundant code.

5ac7eace2d KEYS: Add a facility to restrict new links into a keyring
Add a facility whereby proposed new links to be added to a keyring can be
vetted, permitting them to be rejected if necessary.  This can be used to
block public keys from which the signature cannot be verified or for which
the signature verification fails.  It could also be used to provide
blacklisting.

This affects operations like add_key(), KEYCTL_LINK and KEYCTL_INSTANTIATE.

To this end:

 (1) A function pointer is added to the key struct that, if set, points to
     the vetting function.  This is called as:

	int (*restrict_link)(struct key *keyring,
			     const struct key_type *key_type,
			     unsigned long key_flags,
			     const union key_payload *key_payload),

     where 'keyring' will be the keyring being added to, key_type and
     key_payload will describe the key being added and key_flags[*] can be
     AND'ed with KEY_FLAG_TRUSTED.

     [*] This parameter will be removed in a later patch when
     	 KEY_FLAG_TRUSTED is removed.

     The function should return 0 to allow the link to take place or an
     error (typically -ENOKEY, -ENOPKG or -EKEYREJECTED) to reject the
     link.

     The pointer should not be set directly, but rather should be set
     through keyring_alloc().

     Note that if called during add_key(), preparse is called before this
     method, but a key isn't actually allocated until after this function
     is called.

 (2) KEY_ALLOC_BYPASS_RESTRICTION is added.  This can be passed to
     key_create_or_update() or key_instantiate_and_link() to bypass the
     restriction check.

 (3) KEY_FLAG_TRUSTED_ONLY is removed.  The entire contents of a keyring
     with this restriction emplaced can be considered 'trustworthy' by
     virtue of being in the keyring when that keyring is consulted.

 (4) key_alloc() and keyring_alloc() take an extra argument that will be
     used to set restrict_link in the new key.  This ensures that the
     pointer is set before the key is published, thus preventing a window
     of unrestrictedness.  Normally this argument will be NULL.

 (5) As a temporary affair, keyring_restrict_trusted_only() is added.  It
     should be passed to keyring_alloc() as the extra argument instead of
     setting KEY_FLAG_TRUSTED_ONLY on a keyring.  This will be replaced in
     a later patch with functions that look in the appropriate places for
     authoritative keys.

                                  [h1]  12.0.0.1

host h1 with IP 12.0.0.1 has 2 paths to host h3 at 15.0.0.5:

    root@h1:~# ip ro ls
    ...
    12.0.0.0/24 dev swp1  proto kernel  scope link  src 12.0.0.1
    15.0.0.0/16
            nexthop via 12.0.0.2  dev swp1 weight 1
            nexthop via 12.0.0.3  dev swp1 weight 1
    ...

If the link between tor3 and tor1 is down and the link between tor1
and tor2 then tor1 is effectively cut-off from h1. Yet the route lookups
in h1 are alternating between the 2 routes: ping 15.0.0.5 gets one and
ssh 15.0.0.5 gets the other. Connections that attempt to use the
12.0.0.2 nexthop fail since that neighbor is not reachable:

    root@h1:~# ip neigh show
    ...
    12.0.0.3 dev swp1 lladdr 00:02:00:00:00:1b REACHABLE
    12.0.0.2 dev swp1  FAILED
    ...

The failed path can be avoided by considering known neighbor information
when selecting next hops. If the neighbor lookup fails we have no
knowledge about the nexthop, so give it a shot. If there is an entry
then only select the nexthop if the state is sane. This is similar to
what fib_detect_death does.

To maintain backward compatibility use of the neighbor information is
based on a new sysctl, fib_multipath_use_neigh.

8ee26530bb powerpc/eeh: rename EEH from "extended" to "enhanced" error handling
IBM online documentation for EEH uses "extended error handling" and
"enhanced error handling" to refer to the same thing, in different
places.  The only place mentioning it as "enhanced error handling" in the
kernel is the MAINTAINERS file, and it's "extended" in some documentation.

IBM originally defined EEH as "enhanced error handling", so standardise
all mentions of EEH to use that term.

b72db4005f dmaengine: vdma: Add 64 bit addressing support to the driver
This VDMA  is a soft ip, which can be programmed to support
32 bit addressing or greater than 32 bit addressing.

When the VDMA ip is configured for 32 bit address space
the buffer address is specified by a single register
(0x5C for MM2S and 0xAC for S2MM channel).

When the  VDMA core is configured for an address space greater
than 32 then each buffer address is specified by a combination of
two registers.

The first register specifies the LSB 32 bits of address,
while the next register specifies the MSB 32 bits of address.

For example, 5Ch will specify the LSB 32 bits while 60h will
specify the MSB 32 bits of the first start address.
So we need to program two registers at a time.

This patch adds the 64 bit addressing support to the vdma driver.

75f3a1018f switchdev: Use switch ID in suggested udev rule
Since there can be multiple switch ASICs on the same system we should
use the switch ID in order to differentiate between them and set the
switch name (e.g. swX) accordingly.

Also, replace the order of the "Switch ID" and "Port Netdev Naming"
sections following the above change.

 Drivers
 * staging wide
   - convert bare unsigned usage to unsigned int to comply with coding style.
 * non staging wide:
   - since boiler plate gpio handling of interrupts has been moved into the
    ACPI core we don't need to include gpio/consumer.h in a load of drivers so
    drop it.
 * ad7606
   - fix an endian casting sparse warning.
 * ak8975
   - fix a possible unitialized warning from gcc.
   - drop and unused field left over from earlier cleanups
   - fix a missing regulator_disable on exit.
 * at91-sama5d2
   - typo and indentation
   - missing IOMEM dependency.
   - cleanup mode register usage by avoidling erasing whole thing when changing
   the sampling frequency.
 * bmc150
   - use the core demux and available_scan_masks to simplify buffer handling
   - optimize the transfers in the trigger handler now we have a magic function
   to emulate bulk reads (under circumstances met here).  This matters with some
   rather dumb i2c adapters in particular.
   - use a single regmap_conf for all bus types as they were all the same.
 * bmg160
   - use the core demux and available_scan_masks to simplify the buffer handling
   - optimize the transfers in the trigger handler now we have a magic funciton
   to emulate bulk rads (under circumstances met here).
   - drop gpio interrupt probing from the driver (ACPI) as now handled by the
   ACPI core.
 * ina2xx-adc
   - update the CALIB register when RShunt changes.
   - fix scale for VShunt - in reality this error canceled out when used.
 * isl29028
   - use regmap to retrieve the struct device instead of carrying a second
   copy of it around.
 * kxcjk-1013
   - use core demux
   - optimize i2c transfers in the trigger handler.
 * mcp4531
   - refactor to use a pointer to access model parameters instead of indexing
     into the array each time.
 * mma8452
   - style fixes
   - avoid swtiching to active whenever the config changes
   - add missin i2c_device_id for mma8451
 * mpu6050
   - fix possible NULL dereference.
   - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
 * ms5611
   - fix a missing regulator_disable that left the regulator on during removal.
 * mxc4005
   - drop gpio interrupt handling for ACPI case from driver as the core now
   handles this case.
 * st-sensors
   - note that there are only ever a maximum of 3 axis on current st-sensors
   so just allocate a fixed sized buffer big enough for that.
 * tpl0102
   - change the i2c_check_functionality condition to bring it inline with other
     IIO users as EOPNOTSUPP.
 * tsl2563
   - replace deprecated flush_scheduled_work

4a2d057e4f Merge branch 'PAGE_CACHE_SIZE-removal'
Merge PAGE_CACHE_SIZE removal patches from Kirill Shutemov:
 "PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
  ago with promise that one day it will be possible to implement page
  cache with bigger chunks than PAGE_SIZE.

  This promise never materialized.  And unlikely will.

  Let's stop pretending that pages in page cache are special.  They are
  not.

  The first patch with most changes has been done with coccinelle.  The
  second is manual fixups on top.

  The third patch removes macros definition"

[ I was planning to apply this just before rc2, but then I spaced out,
  so here it is right _after_ rc2 instead.

  As Kirill suggested as a possibility, I could have decided to only
  merge the first two patches, and leave the old interfaces for
  compatibility, but I'd rather get it all done and any out-of-tree
  modules and patches can trivially do the converstion while still also
  working with older kernels, so there is little reason to try to
  maintain the redundant legacy model.    - Linus ]

* PAGE_CACHE_SIZE-removal:
  mm: drop PAGE_CACHE_* and page_cache_{get,release} definition
  mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage

903589ca71 ARM: 8554/1: kernel: pci: remove pci=firmware command line parameter handling
According to kernel documentation, the pci=firmware command line
parameter is only meant to be used on IXP2000 ARM platforms to prevent
the kernel from assigning PCI resources configured by the bootloader.

Since the IXP2000 ARM platforms support has been removed from the
kernel in commit:

commit c65f2abf54 ("ARM: remove ixp23xx and ixp2000 platforms")

its platforms specific kernel parameters should be removed
too from the kernel documentation along with the kernel code
currently handling them in that they have just become obsolete.

This patch removes the pci=firmware command line parameter handling
from ARM code and the related kernel parameters documentation
section.

commit 3ba7222ac9
"arm/versatile: Add device tree support" but was never used

Versatile flash chips are actually just standard CFI chips,
but they have one or two bits in a system controller to control
VPP and write protection. Let's use this compatible string in
conjunction with "cfi-flash" to indicate that we have a
normal CFI flash with some extra Versatile-specific protection.

17dcc37e3e ata: ahci-platform: Add ports-implemented DT bindings.
On some SOCs PORTS_IMPL register value is never programmed by the
firmware and left at zero value. Which means that no sata ports are
available for software. AHCI driver used to cope up with this by
fabricating the port_map if the PORTS_IMPL register is read zero,
but recent patch broke this workaround as zero value was valid for
NVMe disks.

This patch adds ports-implemented DT bindings as workaround for this issue
in a way that DT can can override the PORTS_IMPL register in cases where
the firmware did not program it already.

1c532e00a0 x86/platform/uv: Disable UV BAU by default
For several years, the common practice has been to boot UVs with the
"nobau" parameter on the command line, to disable the BAU.  We've
decided that it makes more sense to just disable the BAU by default in
the kernel, and provide the option to turn it on, if desired.

For now, having the on/off switch doesn't buy us any more than just
reversing the logic would, but we're working towards having the BAU
enabled by default on UV4.  When those changes are in place, having the
on/off switch will make more sense than an enable flag, since the
default behavior will be different depending on the system version.

I've also added a bit of documentation for the new parameter to
Documentation/kernel-parameters.txt.

49db08c358 chrdev: emit a warning when we go below dynamic major range
Currently a dynamically allocated character device major is taken
from 254 and downward. This mechanism is used for RTC, IIO and a
few other subsystems.

The kernel currently has no check prevening these dynamic
allocations from eating into the assigned numbers at 233 and
downward.

In a recent test it was reported that so many dynamic device
majors were used on a test server, that the major number for
infiniband (231) was stolen. This occurred when allocating a new
major number for GPIO chips. The error messages from the kernel
were not helpful. (See: https://lkml.org/lkml/2016/2/14/124)

This patch adds a defined lower limit of the dynamic major
allocation region will henceforth emit a warning if we start to
eat into the assigned numbers. It does not do any semantic
changes and will not change the kernels behaviour: numbers will
still continue to be stolen, but we will know from dmesg what
is going on.

This also updates the Documentation/devices.txt to clearly
reflect that we are using this range of major numbers for dynamic
allocation.

698f415cf5 Merge tag 'ofs-pull-tag-1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux
Pull orangefs filesystem from Mike Marshall.

This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months.  From
the documentation file:

 "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
  is ideal for large storage problems faced by HPC, BigData, Streaming
  Video, Genomics, Bioinformatics.

  Orangefs, originally called PVFS, was first developed in 1993 by Walt
  Ligon and Eric Blumer as a parallel file system for Parallel Virtual
  Machine (PVM) as part of a NASA grant to study the I/O patterns of
  parallel programs.

  Orangefs features include:

    - Distributes file data among multiple file servers
    - Supports simultaneous access by multiple clients
    - Stores file data and metadata on servers using local file system
      and access methods
    - Userspace implementation is easy to install and maintain
    - Direct MPI support
    - Stateless"

see Documentation/filesystems/orangefs.txt for more in-depth details.

895a1067d5 SCSI misc on 20160326
The only new stuff which missed the first pull request is an update to
 the UFS driver.  The rest is an assortment of bug fixes and minor
 tweaks which appeared recently (some are fixes for recent code and
 some are stuff spotted recently by the checkers or the new gcc-6
 compiler [most of Arnd's stuff]).

Pull more power management and ACPI updates from Rafael Wysocki:
 "The second batch of power management and ACPI updates for v4.6.

  Included are fixups on top of the previous PM/ACPI pull request and
  other material that didn't make into it but still should go into 4.6.

  Among other things, there's a fix for an intel_pstate driver issue
  uncovered by recent cpufreq changes, a workaround for a boot hang on
  Skylake-H related to the handling of deep C-states by the platform and
  a PCI/ACPI fix for the handling of IO port resources on non-x86
  architectures plus some new device IDs and similar.

  Specifics:

   - Fix for an intel_pstate driver issue related to the handling of MSR
     updates uncovered by the recent cpufreq rework (Rafael Wysocki).

8a20a04bda ARM: DT changes, part 2
Here are some final updates for ARM SoC specific dts files:
 
 * The i.MX changes were sent relatively late, and had a dependency
   on the clk tree, so I delayed that a bit. Support for the new
   i.MX6qp SoC and a couple of new boards is added in this branch.
 
 * Uniphier renames a few files to match the final product names
   that were decided by the company, kudos to the kernel developer(s)
   for getting support upstream before the product release.
   Also two boards are added. The patches were posted early enough
   and nice overall, but we forgot to apply them and decided to
   give it some more time in linux-next
 
 * at91 has two small bug fixes.

Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276b5 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276b5, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276b5 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

   Fix things to ignore such bogus trip points.  (Zhang Rui)

 - Introduce Mediatek thermal driver.  (Sascha Hauer)

 - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
   Dewangan)

 - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof
   Kozlowski)

 - Introduce Skylake support in intel_pch_thermal driver.  (Srinivas

33c1f638a0 The clk changes for this release cycle are mostly dominated by
new device support in terms of LoC, but there has been some cleanup
 in the core as well as the usual minor clk additions to various
 drivers.
 
 Core:
 
  - parent tracking has been simplified
 
  - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
 
  - of_clk_init() doesn't consider disabled DT nodes anymore
 
  - clk_unregister() had an error path bug squashed
 
  - of_clk_get_parent_count() has been fixed to only return unsigned ints
 
  - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
 
 New Drivers:
 
  - NXP LPC18xx creg
 
  - QCOM IPQ4019 GCC
 
  - TI dm814x ADPLL

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull more rdma updates from Doug Ledford:
 "Round two of 4.6 merge window patches.

  This is a monster pull request.  I held off on the hfi1 driver updates
  (the hfi1 driver is intimately tied to the qib driver and the new
  rdmavt software library that was created to help both of them) in my
  first pull request.  The hfi1/qib/rdmavt update is probably 90% of
  this pull request.  The hfi1 driver is being left in staging so that
  it can be fixed up in regards to the API that Al and yourself didn't
  like.  Intel has agreed to do the work, but in the meantime, this
  clears out 300+ patches in the backlog queue and brings my tree and
  their tree closer to sync.

  This also includes about 10 patches to the core and a few to mlx5 to
  create an infrastructure for configuring SRIOV ports on IB devices.
  That series includes one patch to the net core that we sent to netdev@
  and Dave Miller with each of the three revisions to the series.  We
  didn't get any response to the patch, so we took that as implicit
  approval.

  Finally, this series includes Intel's new iWARP driver for their x722
  cards.  It's not nearly the beast as the hfi1 driver.  It also has a
  linux-next merge issue, but that has been resolved and it now passes
  just fine.

  Summary:

   - A few minor core fixups needed for the next patch series

   - The IB SRIOV series.  This has bounced around for several versions.

5c9a8750a6 kernel: add kcov code coverage
kcov provides code coverage collection for coverage-guided fuzzing
(randomized testing).  Coverage-guided fuzzing is a testing technique
that uses coverage feedback to determine new interesting inputs to a
system.  A notable user-space example is AFL
(http://lcamtuf.coredump.cx/afl/).  However, this technique is not
widely used for kernel testing due to missing compiler and kernel
support.

kcov does not aim to collect as much coverage as possible.  It aims to
collect more or less stable coverage that is function of syscall inputs.
To achieve this goal it does not collect coverage in soft/hard
interrupts and instrumentation of some inherently non-deterministic or
non-interesting parts of kernel is disbled (e.g.  scheduler, locking).

Currently there is a single coverage collection mode (tracing), but the
API anticipates additional collection modes.  Initially I also
implemented a second mode which exposes coverage in a fixed-size hash
table of counters (what Quentin used in his original patch).  I've
dropped the second mode for simplicity.

This patch adds the necessary support on kernel side.  The complimentary
compiler support was added in gcc revision 231296.

We've used this support to build syzkaller system call fuzzer, which has
found 90 kernel bugs in just 2 months:

  https://github.com/google/syzkaller/wiki/Found-Bugs

We've also found 30+ bugs in our internal systems with syzkaller.
Another (yet unexplored) direction where kcov coverage would greatly
help is more traditional "blob mutation".  For example, mounting a
random blob as a filesystem, or receiving a random blob over wire.

Why not gcov.  Typical fuzzing loop looks as follows: (1) reset
coverage, (2) execute a bit of code, (3) collect coverage, repeat.  A
typical coverage can be just a dozen of basic blocks (e.g.  an invalid
input).  In such context gcov becomes prohibitively expensive as
reset/collect coverage steps depend on total number of basic
blocks/edges in program (in case of kernel it is about 2M).  Cost of
kcov depends only on number of executed basic blocks/edges.  On top of
that, kernel requires per-thread coverage because there are always
background threads and unrelated processes that also produce coverage.
With inlined gcov instrumentation per-thread coverage is not possible.

kcov exposes kernel PCs and control flow to user-space which is
insecure.  But debugfs should not be mapped as user accessible.

Based on a patch by Quentin Casasnovas.

3873938068 fat: add config option to set UTF-8 mount option by default
FAT has long supported its own default file name encoding config
setting, separate from CONFIG_NLS_DEFAULT.

However, if UTF-8 encoded file names are desired FAT character set
should not be set to utf8 since this would make file names case
sensitive even if case insensitive matching is requested.  Instead,
"utf8" mount options should be provided to enable UTF-8 file names in
FAT file system.

Unfortunately, there was no possibility to set the default value of this
option so on UTF-8 system "utf8" mount option had to be added manually
to most FAT mounts.

This patch adds config option to set such default value.

d750c42ac2 ocfs2: add feature document for online file check
This document will describe OCFS2 online file check feature.  OCFS2 is
often used in high-availaibility systems.  However, OCFS2 usually
converts the filesystem to read-only when encounters an error.  This may
not be necessary, since turning the filesystem read-only would affect
other running processes as well, decreasing availability.

Then, a mount option (errors=continue) is introduced, which would return
the -EIO errno to the calling process and terminate furhter processing
so that the filesystem is not corrupted further.  The filesystem is not
converted to read-only, and the problematic file's inode number is
reported in the kernel log.  The user can try to check/fix this file via
online filecheck feature.
