platform-drivers-x86 for v4.15-1
For this cycle we have quite an update for the Dell SMBIOS driver including WMI work to provide an interface for SMBIOS tokens via sysfs and WMI support for 2017+ Dell laptop models. SMM dispatcher code is split into a separate driver followed by a new WMI dispatcher. The latter provides a character device interface to user space. The pull request contains a merge of immutable branch from Wolfram Sang in order to apply a dependent fix to the Intel CherryTrail Battery Management driver. Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0 support is added for Intel Skylake. Peaq WMI hotkeys driver gets its own maintainer and white list of supported models. Silead DMI is expanded to support few additional platforms. Tablet mode via GMMS ACPI method is added to support some ThinkPad tablets. Two commits appear here which were previously merged during the v4.14-rcX cycle: - |

We have two changes to the core framework this time around. The first being a
large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis.

libnvdimm for 4.15
* Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable
'userspace flush' of persistent memory updates via filesystem-dax
mappings. It arranges for any filesystem metadata updates that may be
required to satisfy a write fault to also be flushed ("on disk") before
the kernel returns to userspace from the fault handler. Effectively
every write-fault that dirties metadata completes an fsync() before
returning from the fault handler. The new MAP_SHARED_VALIDATE mapping
type guarantees that the MAP_SYNC flag is validated as supported by the
filesystem's ->mmap() file operation.
* Add support for the standard ACPI 6.2 label access methods that
replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods. This
enables interoperability with environments that only implement the
standardized methods.
* Add support for the ACPI 6.2 NVDIMM media error injection methods.
* Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for latch
last shutdown status, firmware update, SMART error injection, and
SMART alarm threshold control.
* Cleanup physical address information disclosures to be root-only.
* Fix revalidation of the DIMM "locked label area" status to support
dynamic unlock of the label area.
* Expand unit test infrastructure to mock the ACPI 6.2 Translate SPA
(system-physical-address) command and error injection commands.

Pull ARM SoC driver updates from Arnd Bergmann:
"This branch contains platform-related driver updates for ARM and
ARM64, these are the areas that bring the changes:
New drivers:
- driver support for Renesas R-Car V3M (R8A77970)
- power management support for Amlogic GX
- a new driver for the Tegra BPMP thermal sensor
- a new bus driver for Technologic Systems NBUS

[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
because the R8A77970 driver is missing a header file that came from
that pull.
The fact that this got merged afterwards only fixes it at this point,
and bisection of that driver will fail if/when you walk into the
history of that driver. - Linus ]

ARM: Device-tree updates for 4.15
We add device tree files for a couple of additional SoCs in various areas:
Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
Amlogic A113D for audio, and Renesas R-Car V3M for automotive.
As usual, lots of new boards get added based on those and other SoCs:
- Actions S500 based CubieBoard6 single-board computer
- Amlogic Meson-AXG A113D based development board
- Amlogic S912 based Khadas VIM2 single-board computer
- Amlogic S912 based Tronsmart Vega S96 set-top-box
- Allwinner H5 based NanoPi NEO Plus2 single-board computer
- Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers
- Allwinner A83T based TBS A711 Tablet
- Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8
- Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500
wireless access points and routers
- NXP i.MX51 based Zodiac Inflight Innovations RDU1 board
- NXP i.MX53 based GE Healthcare PPD biometric monitor
- NXP i.MX6 based Pistachio single-board computer
- NXP i.MX6 based Vining-2000 automotive diagnostic interface
- NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants
- Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
- Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet
- Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA
- Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board
- Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards
- Renasas r8a7745 based iWave G22D-SODIMM SoM
- Rockchip rk3288 based Amarula Vyasa single-board computer
- Samsung Exynos5800 based Odroid HC1 single-board computer
For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic
and Allwinner platforms, but others were also active.
Rob Herring and many others worked on reducing the number of issues that
the latest version of 'dtc' now warns about. Unfortunately there is still
a lot left to do.
A rework of the ARM foundation model introduced several new files
for common variations of the model.

ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added
drivers or features that people have started using. For the changed
lines lines, we have mostly cleanups, the affected platforms are
OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus
driver, with the intention of cleaning up more legacy code.
Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now
with a Quad-Core ARM Cortex-A7. According to the manufacturer,
it is intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
of chips meant for managed gigabit ethernet switches, based
around a Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2
and Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation.

This is the bulk of pin control changes for the v4.15
kernel cycle:
Core:
- The pin control Kconfig entry PINCTRL is now turned into
a menuconfig option. This obviously has the implication of
making the subsystem menu visible in menuconfig. This is
happening because of two things:
- Intel have started to deploy and depend on pin controllers
in a way that is affecting users directly. This happens
on the highly integrated laptop chipsets named after
geographical places: baytrail, broxton, cannonlake,
cedarfork, cherryview, denverton, geminilake, lewisburg,
merrifield, sunrisepoint... It started a while back and
now it is ever more evident that this is crucial
infrastructure for x86 laptops and not an embedded
obscurity anymore. Users need to be aware.
- Pin control expanders on I2C and SPI that are
arch-agnostic. Currently Semtech SX150X and Microchip
MCP28x08 but more are expected. Users will have to be
able to configure these in directly for their set-up.
- Just go and select GPIOLIB now that we made sure that
GPIOLIB is a very vanilla subsystem. Do not depend on
it, if we need it, select it.
- Exposing the pin control subsystem in menuconfig uncovered
a bunch of obscure bugs that are now hopefully fixed,
all more or less pertaining to Blackfin.
- Unified namespace for cross-calls between pin control and
GPIO.
- New support for clock skew/delay generic DT bindings
and generic pin config options for this.
- Minor documentation improvements.
Various:
- The Renesas SH-PFC pin controller has evolved a lot. It seems
Renesas are churning out new SoCs by the minute.
- A bunch of non-critical fixes for the Rockchip driver.
- Improve the use of library functions instead of open coding.
- Support the MCP28018 variant in the MCP28x08 driver.
- Static constifying.

Char/Misc patches for 4.15-rc1
Here is the big set of char/misc and other driver subsystem patches for 4.15-rc1. There are small changes all over here, hyperv driver updates, pcmcia driver updates, w1 driver updats, vme driver updates, nvmem driver updates, and lots of other little one-off driver updates as well. The shortlog has the full details. Note, there will be a merge conflict in drivers/misc/lkdtm_core.c when merging to your tree as one lkdtm patch came in through the perf tree as well as this one. The resolution is to take the const change that this tree provides. All of these have been in linux-next for quite a while with no reported issues.

Lots of driver updates across the stack, a huge number of static analysis cleanups including a close to 50 patch series from Bart Van Assche, and a number of new features inside the stack such as general CQ moderation support. Nothing really stands out, but there might be a few conflicts as you take things in. In particular, the cleanups touched some of the same lines as the new timer_setup changes. Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday.

"The big highlight is support for the Scalable Vector Extension (SVE)
which required extensive ABI work to ensure we don't break existing
applications by blowing away their signal stack with the rather large
new vector context (<= 2 kbit per vector register). There's further
work to be done optimising things like exception return, but the ABI
is solid now.
Much of the line count comes from some new PMU drivers we have, but
they're pretty self-contained and I suspect we'll have more of them in
future.

RISC-V Port for Linux 4.15 v9
This tag contains the core RISC-V Linux port, which has been through
nine rounds of review on various mailing lists. The port is not
complete: there's some cleanup patches moving through the review
process, a whole bunch of drivers that need some work, and a lot of
feature additions that will be needed.
The patches contained in this tag have been through nine rounds of
review on the various mailing lists. I have some outstanding cleanup
patches, but since there's been so much review on these patches I
thought it would be best to submit them as-is and then submit explicit
cleanup patches so everyone can review them. This first patch set is
big enough that it's a bit of a pain to constantly rewrite, and it's
caused a few headaches with various contributors.
The port is definately a work in progress. While what's there builds
and boots with 4.14, it's a bit hard to actually see anything happen
because there are no device drivers yet. I maintain a staging branch
that contains all the device drivers and cleanup that actually works,
but those patches won't all be ready for a while. I'd like to get what
we currently have into your tree so everyone can start working from a
single base -- of particular importance is allowing the glibc
upstreaming process to proceed so we can sort out any possibly lingering
user-visible ABI problems we might have.
Copied below is the ChangeLog that contains the history of this patch
set:
(v9) As per suggestions on our v8 patch set, I've split the core architecture code
out from our drivers and would like to submit this patch set to be included
into linux-next, with the goal being to be merged in during the next merge
window. This patch set is based on 4.14-rc2, but if it's better to have it
based on something else then I can change it around.
This patch set contains just the core arch code for RISC-V, so while it builds
an nominally boots, you can't print or take an interrupt so it's not that
useful. If you're looking to actually boot a system it would probably be
better to use the full patch set listed below.
We've collected a handful of tags from reviewers, and the remainder of the
patch set only got minimal feedback last time. Here's what changed:
* We now use the device tree to initialize the timer driver so it's less
tighly coupled with the arch port.
* I cleaned up the defconfigs -- there's actually now just one, and it's
empty. For now I think we're OK with what the kernel sets as defaults, but
I anticipate we'll begin to expand this as people start to use the port
more.
* The VDSO symbols version is sane.
* We WFI while spinning in the boot loop.
* A handful of comments have been added.
While there are still a handful of FIXMEs in this patch set, we've started to
get enough interest from various users and contributors that maintaining an out
of tree patch set is starting to become a big burden. Hopefully the patches
are good enough to merge now, which will at least get everyone working in a
more reasonable manner as we clean up the remaining issues.
This patch set is also availiable on github
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9-arch
as is the entire patch set necessary to get a more functional RISC-V system up
and running, including a handful of patches that aren't ready for upstream yet.
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9
Hopefully I've managed to get everyone's feedback
Here's the change highlights from the whole patch set:
(v8) I know it may not be the ideal time to submit a patch set right now, as
it's the middle of the merge window, but things have calmed down quite a bit in
the last month so I thought it would be good to get everyone on the same page.
There's been a handful of changes since the last patch set, but most of them
are fairly minor:
* We changed PAGE_OFFSET to allowing mapping more physical memory on 64-bit
systems. This is user configurable, as it triggers a different code model
that generates slightly less efficient code.
* The device tree binding documentation is back, I'd managed to lose it at some
point.
* We now pass the atomic64 test suite. The SBI timer driver has been
* refactored.
(v7) It's been a while since my last patch set, but the changes han been fairly
minimal:
* The PCI cleanup patches have been dropped, we'll do them as a separate patch
set later.
* We've the Kconfig entries from CONFIG_ISA_* to CONFIG_RISCV_ISA_*, to make
grep easier.
* There have been a handful of memory model related tweaks in I/O land,
particularly relating the PCI and the upcoming platform specification.
There are significant comments in the relevant files. This is still a WIP,
but I think we're close to getting as good as we're going to get until we
end up with some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are pretty
minimal:
* The patch set is now based on linux-next/master, which I believe is a better
base now that we're getting closer to upstream.
* EARLY_PRINTK is no longer an option. Since the SBI console is reasonable,
there's no penalty to enabling it (and thus no benefit to disabling it).
* The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly similar to the
v4 patch set. The most interesting changes include:
* We've moved back to a single patch set.
* SMP support has been fixed, I was accidentally running on a non-SMP
configuration. There were various mistakes all over the tree as a result of
this.
* The cmpxchg syscalls have been removed, as they were deemed a bad idea. As
a result, RISC-V Linux systems mandate the A extension. The corresponding
Kconfig entry to enable builds on non-A systems has been removed.
* A few more atomic fixes: mostly fence changes, but those resulted in a
handful of additional macros that were no longer necessary.
* riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
* The cmpxchg64 syscall is no longer enabled on 32-bit systems. It's not
possible to provide this on SMP systems, and it's not necessary as glibc
knows not to call it.
* We provide a ELF_HWCAP so users can determine the ISA of the machine the
kernel is running on.
* The multi-line comments are in a better form.
* There were a handful of headers that could be replaced with the asm-generic
versions, and a few unnecessary definitions.
* We no longer use printk, but instead use pr_*.
* A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
* We've split out all our drivers into separate patch sets, which I've already
sent out to the relevant maintainers. I haven't included those patches in
this patch set, but some of them are necessary to build our port. A git
tree that contains all our patch sets merged together lives at
<https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v3>.
* The patch set is now split up differently: rather than being split per
directory it is split per topic. Hopefully this will make it easier to
review the port on the mailing list. The split is a bit rough, so you
probably still want to look at the patch set as a whole.
* atomic.h has been completely rewritten and is hopefully now correct. I've
attempted to sanitize the various other memory model related code as well,
and I think it should all be sane now aside from a handful of FIXMEs
commented in the code.
* We've changed the cmpexchg syscall to always exist and to not be
multiplexed. There is also a VDSO entry for compare and exchange, which
allows kernels with the A extension to execute user code without the A
extension reasonably fast.
* Our user-visible register state now contains enough space for the Q
extension for 128-bit floating point, as well as a few words to allow
extensibility to future ISA extensions like the eventual V extension for
vectors.
* A handful of driver cleanups, but these have been split into separate patch
sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
* We've split out our drivers into the right places, which means now there's
a lot more patches. I'll be submitting these patches to various subsystem
maintainers and including them in any future RISC-V patch sets until
they've been merged.
* The SBI console driver has been completely rewritten to use the HVC helpers
and is now significantly smaller.
* We've begun to use weaker barriers as opposed to just the big "fence".
There's still some work to do here, specifically:
- We need fences in the relaxed MMIO functions.
- The non-relaxed MMIO functions are missing R/W bits on their fences.
- Many AMOs need the aq and rl bits set.
* We now have thread_info in task_struct. As a result, sscratch now contains
TP instead of SP. This was necessary because thread_info is no longer on
the stack.
* A few shared routines have been added that we use instead of creating
another arch copy.

contributors that maintaining an out of tree patch set is
starting to become a big burden. Hopefully the patches are good
enough to merge now, which will at least get everyone working in
a more reasonable manner as we clean up the remaining issues.
(v8) I know it may not be the ideal time to submit a patch set right
now, as it's the middle of the merge window, but things have
calmed down quite a bit in the last month so I thought it would
be good to get everyone on the same page. There's been a handful
of changes since the last patch set, but most of them are fairly
minor:
- We changed PAGE_OFFSET to allowing mapping more physical
memory on 64-bit systems. This is user configurable, as it
triggers a different code model that generates slightly less
efficient code.
- The device tree binding documentation is back, I'd managed to
lose it at some point.
- We now pass the atomic64 test suite
- The SBI timer driver has been refactored.
(v7) It's been a while since my last patch set, but the changes han
been fairly minimal:
- The PCI cleanup patches have been dropped, we'll do them as a
separate patch set later.
- We've the Kconfig entries from CONFIG_ISA_* to
CONFIG_RISCV_ISA_*, to make grep easier.
- There have been a handful of memory model related tweaks in
I/O land, particularly relating the PCI and the upcoming
platform specification. There are significant comments in the
relevant files. This is still a WIP, but I think we're close
to getting as good as we're going to get until we end up with
some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are
pretty minimal:
- The patch set is now based on linux-next/master, which I
believe is a better base now that we're getting closer to
upstream.
- EARLY_PRINTK is no longer an option. Since the SBI console is
reasonable, there's no penalty to enabling it (and thus no
benefit to disabling it).
- The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly
similar to the v4 patch set. The most interesting changes
include:
- We've moved back to a single patch set.
- SMP support has been fixed, I was accidentally running on a
non-SMP configuration. There were various mistakes all over
the tree as a result of this.
- The cmpxchg syscalls have been removed, as they were deemed a
bad idea. As a result, RISC-V Linux systems mandate the A
extension. The corresponding Kconfig entry to enable builds
on non-A systems has been removed.
- A few more atomic fixes: mostly fence changes, but those
resulted in a handful of additional macros that were no
longer necessary.
- riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
- The cmpxchg64 syscall is no longer enabled on 32-bit systems.
It's not possible to provide this on SMP systems, and it's
not necessary as glibc knows not to call it.
- We provide a ELF_HWCAP so users can determine the ISA of the
machine the kernel is running on.
- The multi-line comments are in a better form.
- There were a handful of headers that could be replaced with
the asm-generic versions, and a few unnecessary definitions.
- We no longer use printk, but instead use pr_*.
- A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
- We've split out all our drivers into separate patch sets,
which I've already sent out to the relevant maintainers. I
haven't included those patches in this patch set, but some of
them are necessary to build our port.
- The patch set is now split up differently: rather than being
split per directory it is split per topic. Hopefully this
will make it easier to review the port on the mailing list.
The split is a bit rough, so you probably still want to look
at the patch set as a whole.
- atomic.h has been completely rewritten and is hopefully now
correct. I've attempted to sanitize the various other memory
model related code as well, and I think it should all be sane
now aside from a handful of FIXMEs commented in the code.
- We've changed the cmpexchg syscall to always exist and to not
be multiplexed. There is also a VDSO entry for compare and
exchange, which allows kernels with the A extension to
execute user code without the A extension reasonably fast.
- Our user-visible register state now contains enough space for
the Q extension for 128-bit floating point, as well as a few
words to allow extensibility to future ISA extensions like
the eventual V extension for vectors.
- A handful of driver cleanups, but these have been split into
separate patch sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
- We've split out our drivers into the right places, which
means now there's a lot more patches. I'll be submitting
these patches to various subsystem maintainers and including
them in any future RISC-V patch sets until they've been
merged.
- The SBI console driver has been completely rewritten to use
the HVC helpers and is now significantly smaller.
- We've begun to use weaker barriers as opposed to just the big
"fence". There's still some work to do here, specifically:
- We need fences in the relaxed MMIO functions.
- The non-relaxed MMIO functions are missing R/W bits on their fences.
- Many AMOs need the aq and rl bits set.
- We now have thread_info in task_struct. As a result, sscratch
now contains TP instead of SP. This was necessary because
thread_info is no longer on the stack.
- A few shared routines have been added that we use instead of
creating another arch copy"

sound updates for 4.15-rc1
There are no big surprising changes in this cycle, yet not too
boring, either. The biggest change from diffstat POV is the removal
of the legacy OSS driver codes that have been already disabled for a
long time. This will bring a few trivial merge conflicts.
As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support. Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.
Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the malicious
device accesses with a new helper code for endpoint sanity check.
- Lots of cleanups for ASoC Intel platform code, including support for
their open source audio firmware.
- Continued ASoC core componentization works.
- Support for scaling MCLK with sample rate in ASoC simple-card.
- Stabler PCM hot-unplug capability, especially for ASoC usages.

"This contains two bigger than usual tree-wide changes this time. They
all have proper acks, caused no merge conflicts in linux-next where

arch/* and drivers/mfd/*)
- adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)
Other notable changes:
- i2c_boardinfo can now carry a dev_name to be used when the device
is created. This is because some devices in ACPI world need fixed
names to find the regulators.
- the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.
- at24 driver has way better OF support. And it has a new maintainer.

This is the bulk of GPIO changes for the v4.15 kernel cycle:
CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.

Merge branch 'for-4.15/block' of git://git.kernel.dk/linux-block
Pull core block layer updates from Jens Axboe:
"This is the main pull request for block storage for 4.15-rc1.
Nothing out of the ordinary in here, and no API changes or anything
like that. Just various new features for drivers, core changes, etc.
In particular, this pull request contains:
- A patch series from Bart, closing the whole on blk/scsi-mq queue
quescing.
- A series from Christoph, building towards hidden gendisks (for
multipath) and ability to move bio chains around.
- NVMe
- Support for native multipath for NVMe (Christoph).
- Userspace notifications for AENs (Keith).
- Command side-effects support (Keith).
- SGL support (Chaitanya Kulkarni)
- FC fixes and improvements (James Smart)
- Lots of fixes and tweaks (Various)
- bcache
- New maintainer (Michael Lyle)
- Writeback control improvements (Michael)
- Various fixes (Coly, Elena, Eric, Liang, et al)
- lightnvm updates, mostly centered around the pblk interface
(Javier, Hans, and Rakesh).
- Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)
- Writeback series that fix the much discussed hundreds of millions
of sync-all units. This goes all the way, as discussed previously
(me).
- Fix for missing wakeup on writeback timer adjustments (Yafang
Shao).
- Fix laptop mode on blk-mq (me).
- {mq,name} tupple lookup for IO schedulers, allowing us to have
alias names. This means you can use 'deadline' on both !mq and on
mq (where it's called mq-deadline). (me).
- blktrace race fix, oopsing on sg load (me).
- blk-mq optimizations (me).
- Obscure waitqueue race fix for kyber (Omar).
- NBD fixes (Josef).
- Disable writeback throttling by default on bfq, like we do on cfq
(Luca Miccio).
- Series from Ming that enable us to treat flush requests on blk-mq
like any other request. This is a really nice cleanup.
- Series from Ming that improves merging on blk-mq with schedulers,
getting us closer to flipping the switch on scsi-mq again.
- BFQ updates (Paolo).
- blk-mq atomic flags memory ordering fixes (Peter Z).
- Loop cgroup support (Shaohua).
- Lots of minor fixes from lots of different folks, both for core and
driver code"

Pull power management updates from Rafael Wysocki:
"There are no real big ticket items here this time.
The most noticeable change is probably the relocation of the OPP
(Operating Performance Points) framework to its own directory under
drivers/ as it has grown big enough for that. Also Viresh is now going
to maintain it and send pull requests for it to me, so you will see
this change in the git history going forward (but still not right
now).
Another noticeable set of changes is the modifications of the PM core,
the PCI subsystem and the ACPI PM domain to allow of more integration
between system-wide suspend/resume and runtime PM. For now it's just a
way to avoid resuming devices from runtime suspend unnecessarily
during system suspend (if the driver sets a flag to indicate its
readiness for that) and in the works is an analogous mechanism to
allow devices to stay suspended after system resume.
In addition to that, we have some changes related to supporting
frequency-invariant CPU utilization metrics in the scheduler and in
the schedutil cpufreq governor on ARM and changes to add support for
device performance states to the generic power domains (genpd)
framework.
The rest is mostly fixes and cleanups of various sorts.
Specifics:
- Relocate the OPP (Operating Performance Points) framework to its
own directory under drivers/ and add support for power domain
performance states to it (Viresh Kumar).
- Modify the PM core, the PCI bus type and the ACPI PM domain to

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

OpenRISC updates for v4.15
Small Things:
- Move OpenRISC docs into Documentation and clean them up
- Document previously undocumented devicetree bindings
- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as true"
get the architecture ready for SMP.
- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of the
necessary data-structures to be per-cpu.
- The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks
- sleep instead of spin on secondary wait
- support framepointers and STACKTRACE_SUPPORT
- enable LOCKDEP_SUPPORT and irqflags tracing
- timer sync: Add tick timer sync logic
- fix possible deadlock in timer sync, pointed out by mips guys
Note: the irqchip patch was reviewed with Marc and we agreed to push it
together with these patches.

Merge tag 'for-linus' of git://github.com/openrisc/linux
Pull OpenRISC updates from Stafford Horne:
"The OpenRISC work is a bit more interesting this time, adding SMP
support and a few general cleanups.
Small Things:
- Move OpenRISC docs into Documentation and clean them up
- Document previously undocumented devicetree bindings
- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as
true" get the architecture ready for SMP.
- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of
the necessary data-structures to be per-cpu.
The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks
- sleep instead of spin on secondary wait
- support framepointers and STACKTRACE_SUPPORT
- enable LOCKDEP_SUPPORT and irqflags tracing
- timer sync: Add tick timer sync logic
- fix possible deadlock in timer sync, pointed out by mips guys
Note: the irqchip patch was reviewed with Marc and we agreed to push
it together with these patches"

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
"Since Martin is on vacation you get the s390 pull request for the
v4.15 merge window this time from me.
Besides a lot of cleanups and bug fixes these are the most important
changes:
- a new regset for runtime instrumentation registers
- hardware accelerated AES-GCM support for the aes_s390 module
- support for the new CEX6S crypto cards
- support for FORTIFY_SOURCE
- addition of missing z13 and new z14 instructions to the in-kernel
disassembler
- generate opcode tables for the in-kernel disassembler out of a
simple text file instead of having to manually maintain those
tables
- fast memset16, memset32 and memset64 implementations
- removal of named saved segment support
- hardware counter support for z14
- queued spinlocks and queued rwlocks implementations for s390
- use the stack_depth tracking feature for s390 BPF JIT
- a new s390_sthyi system call which emulates the sthyi (store
hypervisor information) instruction
- removal of the old KVM virtio transport
- an s390 specific CPU alternatives implementation which is used in
the new spinlock code"

Merge branch 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull general security subsystem updates from James Morris:
"TPM (from Jarkko):
- essential clean up for tpm_crb so that ARM64 and x86 versions do
not distract each other as much as before
- /dev/tpm0 rejects now too short writes (shorter buffer than
specified in the command header
- use DMA-safe buffer in tpm_tis_spi
- otherwise mostly minor fixes.
Smack:
- base support for overlafs
Capabilities:
- BPRM_FCAPS fixes, from Richard Guy Briggs:
The audit subsystem is adding a BPRM_FCAPS record when auditing
setuid application execution (SYSCALL execve). This is not expected
as it was supposed to be limited to when the file system actually
had capabilities in an extended attribute. It lists all
capabilities making the event really ugly to parse what is
happening. The PATH record correctly records the setuid bit and
owner. Suppress the BPRM_FCAPS record on set*id.
TOMOYO:
- Y2038 timestamping fixes"
