thermal: power_allocator: relax the requirement of two passive trip points
The power allocator governor currently requires that the thermal zone has at least two passive trip points. If there aren't, the governor refuses to bind to the thermal zone. This commit relaxes that requirement. Now the governor will bind to all thermal zones regardless of how many trip points they have.

Merge branch 'for-4.3/blkcg' of git://git.kernel.dk/linux-block
Pull blk-cg updates from Jens Axboe:
"A bit later in the cycle, but this has been in the block tree for a a
while. This is basically four patchsets from Tejun, that improve our
buffered cgroup writeback. It was dependent on the other cgroup
changes, but they went in earlier in this cycle.
Series 1 is set of 5 patches that has cgroup writeback updates:
- bdi_writeback iteration fix which could lead to some wb's being
skipped or repeated during e.g. sync under memory pressure.
- Simplification of wb work wait mechanism.
- Writeback tracepoints updated to report cgroup.
Series 2 is is a set of updates for the CFQ cgroup writeback handling:
cfq has always charged all async IOs to the root cgroup. It didn't
have much choice as writeback didn't know about cgroups and there
was no way to tell who to blame for a given writeback IO.
writeback finally grew support for cgroups and now tags each
writeback IO with the appropriate cgroup to charge it against.
This patchset updates cfq so that it follows the blkcg each bio is
tagged with. Async cfq_queues are now shared across cfq_group,
which is per-cgroup, instead of per-request_queue cfq_data. This
makes all IOs follow the weight based IO resource distribution
implemented by cfq.
- Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff.
- Other misc review points addressed, acks added and rebased.
Series 3 is the blkcg policy cleanup patches:
This patchset contains assorted cleanups for blkcg_policy methods
and blk[c]g_policy_data handling.
- alloc/free added for blkg_policy_data. exit dropped.
- alloc/free added for blkcg_policy_data.
- blk-throttle's async percpu allocation is replaced with direct
allocation.
- all methods now take blk[c]g_policy_data instead of blkcg_gq or
blkcg.
And finally, series 4 is a set of patches cleaning up the blkcg stats
handling:
blkcg's stats have always been somwhat of a mess. This patchset
tries to improve the situation a bit.
- The following patches added to consolidate blkcg entry point and
blkg creation. This is in itself is an improvement and helps
colllecting common stats on bio issue.
- per-blkg stats now accounted on bio issue rather than request
completion so that bio based and request based drivers can behave
the same way. The issue was spotted by Vivek.
- cfq-iosched implements custom recursive stats and blk-throttle
implements custom per-cpu stats. This patchset make blkcg core
support both by default.
- cfq-iosched and blk-throttle keep track of the same stats
multiple times. Unify them"

proc: export idle flag via kpageflags
As noted by Minchan, a benefit of reading idle flag from /proc/kpageflags is that one can easily filter dirty and/or unevictable pages while estimating the size of unused memory. Note that idle flag read from /proc/kpageflags may be stale in case the page was accessed via a PTE, because it would be too costly to iterate over all page mappings on each /proc/kpageflags read to provide an up-to-date value. To make sure the flag is up-to-date one has to read /sys/kernel/mm/page_idle/bitmap first.

mm: introduce idle page tracking
Knowing the portion of memory that is not used by a certain application or
memory cgroup (idle memory) can be useful for partitioning the system
efficiently, e.g. by setting memory cgroup limits appropriately.
Currently, the only means to estimate the amount of idle memory provided
by the kernel is /proc/PID/{clear_refs,smaps}: the user can clear the
access bit for all pages mapped to a particular process by writing 1 to
clear_refs, wait for some time, and then count smaps:Referenced. However,
this method has two serious shortcomings:
- it does not count unmapped file pages
- it affects the reclaimer logic
To overcome these drawbacks, this patch introduces two new page flags,
Idle and Young, and a new sysfs file, /sys/kernel/mm/page_idle/bitmap.
A page's Idle flag can only be set from userspace by setting bit in
/sys/kernel/mm/page_idle/bitmap at the offset corresponding to the page,
and it is cleared whenever the page is accessed either through page tables
(it is cleared in page_referenced() in this case) or using the read(2)
system call (mark_page_accessed()). Thus by setting the Idle flag for
pages of a particular workload, which can be found e.g. by reading
/proc/PID/pagemap, waiting for some time to let the workload access its
working set, and then reading the bitmap file, one can estimate the amount
of pages that are not used by the workload.
The Young page flag is used to avoid interference with the memory
reclaimer. A page's Young flag is set whenever the Access bit of a page
table entry pointing to the page is cleared by writing to the bitmap file.
If page_referenced() is called on a Young page, it will add 1 to its
return value, therefore concealing the fact that the Access bit was
cleared.
Note, since there is no room for extra page flags on 32 bit, this feature
uses extended page flags when compiled on 32 bit.

pwm: Changes for v4.3-rc1
This set of changes introduces the beginnings of a new API that's based around the concept of states that can be atomically applied. Drivers go to various lengths to implement something similar, which indicates that the core should really be providing the necessary framework. On top of that, there is a bit of cleanup as well as improved kerneldoc and integration into the device-drivers DocBook. Regarding drivers there is a new one for the NXP LPC18xx family of SoCs and a couple of fixes for existing drivers (pca9685, Broadcom Kona and Atmel HLCDC). -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJV8DLwAAoJEN0jrNd/PrOhSf4P/RYwdDGB/xvI0ifXS5p9znNA hr6+MUH87+f9NY1jcDye0RrxIkRsckQ3x3fe/nTmODjCSM/cyrWrVAEKbkqE5bZH LTRT6M6jolSAUGXFTBDuHktYdMU9yaD0PJvm0RgBEC7z2BeBmCgCXTFc4paxw2GA NvikouXZX9XDlXp598pHPFoL92vTLevQQMBHYW9myY8cjAOG0X8Dn05xQaC2kRvJ 5q+OD1D/kIEMJxONrpef7bwzPgCkuGTHqqIIm6gLVoPBPGWz43kaZ5+x/j2E98E9 fkfcP+21GvZ/tdAUEkrRnpy5Jnn+Nk0m+yzPtRkvj4TLwPd93EjumiPg5sb53pys ZfoHgnOAArVxEnTYLQk4IyBWcHyyzIxZBKZZpXkMXjY4QVq6wZLAP+vyCAzcm4tV vHqUN5BYAkwYPUNU58fgFWGHg6rFlb2QSN1bIj5opgygWmRbPgmwVj3trvS2Dkoe NOv47pp0OyWvTvx+wLql8BUt1zK1M6QldfPF6pR4FB18SLyKYH89ZbjHTyGdsuCv SiaWrqNB4eRmEKW1MA20Kc4wlF5c2peXVp2EHeddh/oHPES8IVWBPMPwSkJZrpQb bIUMStKlJ/Y1GPo6Dd7njK/kA3GwwsbYXYHmyPm0IRuAeZKrzGzVSIIljbfpL6Vf LBuKRMQHY4iWtF8A5SmY =ymH8 -----END PGP SIGNATURE----- Merge tag 'pwm/for-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "This set of changes introduces the beginnings of a new API that's based around the concept of states that can be atomically applied.

Pull inifiniband/rdma updates from Doug Ledford:
"This is a fairly sizeable set of changes. I've put them through a
decent amount of testing prior to sending the pull request due to
that.
There are still a few fixups that I know are coming, but I wanted to
go ahead and get the big, sizable chunk into your hands sooner rather
than waiting for those last few fixups.
Of note is the fact that this creates what is intended to be a
temporary area in the drivers/staging tree specifically for some
cleanups and additions that are coming for the RDMA stack. We
deprecated two drivers (ipath and amso1100) and are waiting to hear
back if we can deprecate another one (ehca). We also put Intel's new
hfi1 driver into this area because it needs to be refactored and a
transfer library created out of the factored out code, and then it and
the qib driver and the soft-roce driver should all be modified to use
that library.
I expect drivers/staging/rdma to be around for three or four kernel
releases and then to go away as all of the work is completed and final
deletions of deprecated drivers are done.
Summary of changes for 4.3:
- Create drivers/staging/rdma
- Move amso1100 driver to staging/rdma and schedule for deletion
- Move ipath driver to staging/rdma and schedule for deletion
- Add hfi1 driver to staging/rdma and set TODO for move to regular

IOMMU Updates for Linux v4.3
This time the IOMMU updates are mostly cleanups or fixes. No big new
features or drivers this time. In particular the changes include:
* Bigger cleanup of the Domain<->IOMMU data structures and the
code that manages them in the Intel VT-d driver. This makes
the code easier to understand and maintain, and also easier to
keep the data structures in sync. It is also a preparation
step to make use of default domains from the IOMMU core in the
Intel VT-d driver.
* Fixes for a couple of DMA-API misuses in ARM IOMMU drivers,
namely in the ARM and Tegra SMMU drivers.
* Fix for a potential buffer overflow in the OMAP iommu driver's
debug code
* A couple of smaller fixes and cleanups in various drivers
* One small new feature: Report domain-id usage in the Intel
VT-d driver to easier detect bugs where these are leaked.

zsmalloc: account the number of compacted pages
Compaction returns back to zram the number of migrated objects, which is
quite uninformative -- we have objects of different sizes so user space
cannot obtain any valuable data from that number. Change compaction to
operate in terms of pages and return back to compaction issuer the
number of pages that were freed during compaction. So from now on we
will export more meaningful value in zram<id>/mm_stat -- the number of
freed (compacted) pages.
This requires:
(a) a rename of `num_migrated' to 'pages_compacted'
(b) a internal API change -- return first_page's fullness_group from
putback_zspage(), so we know when putback_zspage() did
free_zspage(). It helps us to account compaction stats correctly.

mm: /proc/pid/smaps:: show proportional swap share of the mapping
We want to know per-process workingset size for smart memory management
on userland and we use swap(ex, zram) heavily to maximize memory
efficiency so workingset includes swap as well as RSS.
On such system, if there are lots of shared anonymous pages, it's really
hard to figure out exactly how many each process consumes memory(ie, rss
+ wap) if the system has lots of shared anonymous memory(e.g, android).
This patch introduces SwapPss field on /proc/<pid>/smaps so we can get
more exact workingset size per process.
Bongkyu tested it. Result is below.
1. 50M used swap
SwapTotal: 461976 kB
SwapFree: 411192 kB
$ adb shell cat /proc/*/smaps | grep "SwapPss:" | awk '{sum += $2} END {print sum}';

$ adb shell cat /proc/*/smaps | grep "Swap:" | awk '{sum += $2} END {print sum}';

pagemap: add mmap-exclusive bit for marking pages mapped only here
This patch sets bit 56 in pagemap if this page is mapped only once. It allows to detect exclusively used pages without exposing PFN: present file exclusive state 0 0 0 non-present 1 1 0 file page mapped somewhere else 1 1 1 file page mapped only here 1 0 0 anon non-CoWed page (shared with parent/child) 1 0 1 anon CoWed page (or never forked) CoWed pages in (MAP_FILE | MAP_PRIVATE) areas are anon in this context. MMap-exclusive bit doesn't reflect potential page-sharing via swapcache: page could be mapped once but has several swap-ptes which point to it.

libnvdimm for 4.3:
1/ Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
mechanism for adding device-driver-discovered memory regions to the
kernel's direct map. This facility is used by the pmem driver to
enable pfn_to_page() operations on the page frames returned by DAX
('direct_access' in 'struct block_device_operations'). For now, the
'memmap' allocation for these "device" pages comes from "System
RAM". Support for allocating the memmap from device memory will
arrive in a later kernel.
2/ Introduce memremap() to replace usages of ioremap_cache() and
ioremap_wt(). memremap() drops the __iomem annotation for these
mappings to memory that do not have i/o side effects. The
replacement of ioremap_cache() with memremap() is limited to the
pmem driver to ease merging the api change in v4.3. Completion of
the conversion is targeted for v4.4.
3/ Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
driver, update the VFS DAX implementation and PMEM api to provide
persistence guarantees for kernel operations on a DAX mapping.
4/ Convert the ACPI NFIT 'BLK' driver to map the block apertures as
cacheable to improve performance.
5/ Miscellaneous updates and fixes to libnvdimm including support
for issuing "address range scrub" commands, clarifying the optimal
'sector size' of pmem devices, a clarification of the usage of the
ACPI '_STA' (status) property for DIMM devices, and other minor
fixes.

"This update has successfully completed a 0day-kbuild run and has

Mostly this is just clean ups and micro optimizations.
The changes with more meat are:
o Allowing the trace event filters to filter on CPU number and process ids
o Two new markers for trace output latency were added
(10 and 100 msec latencies)
o Have tracing_thresh filter function profiling time
I also worked on modifying the ring buffer code for some future
work, and moved the adding of the timestamp around. One of my changes
caused a regression, and since other changes were built on top of it
and already tested, I had to operate a revert of that change. Instead
of rebasing, this change set has the code that caused a regression
as well as the code to revert that change without touching the other
changes that were made on top of it.

userfaultfd: change the read API to return a uffd_msg
I had requests to return the full address (not the page aligned one) to userland. It's not entirely clear how the page offset could be relevant because userfaults aren't like SIGBUS that can sigjump to a different place and it actually skip resolving the fault depending on a page offset. There's currently no real way to skip the fault especially because after a UFFDIO_COPY|ZEROPAGE, the fault is optimized to be retried within the kernel without having to return to userland first (not even self modifying code replacing the .text that touched the faulting address would prevent the fault to be repeated). Userland cannot skip repeating the fault even more so if the fault was triggered by a KVM secondary page fault or any get_user_pages or any copy-user inside some syscall which will return to kernel code. The second time FAULT_FLAG_RETRY_NOWAIT won't be set leading to a SIGBUS being raised because the userfault can't wait if it cannot release the mmap_map first (and FAULT_FLAG_RETRY_NOWAIT is required for that). Still returning userland a proper structure during the read() on the uffd, can allow to use the current UFFD_API for the future non-cooperative extensions too and it looks cleaner as well. Once we get additional fields there's no point to return the fault address page aligned anymore to reuse the bits below PAGE_SHIFT. The only downside is that the read() syscall will read 32bytes instead of 8bytes but that's not going to be measurable overhead. The total number of new events that can be extended or of new future bits for already shipped events, is limited to 64 by the features field of the uffdio_api structure. If more will be needed a bump of UFFD_API will be required.

userfaultfd: linux/Documentation/vm/userfaultfd.txt
This is the latest userfaultfd patchset. The postcopy live migration
feature on the qemu side is mostly ready to be merged and it entirely
depends on the userfaultfd syscall to be merged as well. So it'd be great
if this patchset could be reviewed for merging in -mm.
Userfaults allow to implement on demand paging from userland and more
generally they allow userland to more efficiently take control of the
behavior of page faults than what was available before (PROT_NONE +
SIGSEGV trap).
The use cases are:
1) KVM postcopy live migration (one form of cloud memory
externalization).
KVM postcopy live migration is the primary driver of this work:
http://blog.zhaw.ch/icclab/setting-up-post-copy-live-migration-in-openstack/
http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04873.html
2) postcopy live migration of binaries inside linux containers:
http://thread.gmane.org/gmane.linux.kernel.mm/132662
3) KVM postcopy live snapshotting (allowing to limit/throttle the
memory usage, unlike fork would, plus the avoidance of fork
overhead in the first place).
While the wrprotect tracking is not implemented yet, the syscall API is
already contemplating the wrprotect fault tracking and it's generic enough
to allow its later implementation in a backwards compatible fashion.
4) KVM userfaults on shared memory. The UFFDIO_COPY lowlevel method
should be extended to work also on tmpfs and then the
uffdio_register.ioctls will notify userland that UFFDIO_COPY is
available even when the registered virtual memory range is tmpfs
backed.
5) alternate mechanism to notify web browsers or apps on embedded
devices that volatile pages have been reclaimed. This basically
avoids the need to run a syscall before the app can access with the
CPU the virtual regions marked volatile. This depends on point 4)
to be fulfilled first, as volatile pages happily apply to tmpfs.
Even though there wasn't a real use case requesting it yet, it also
allows to implement distributed shared memory in a way that readonly
shared mappings can exist simultaneously in different hosts and they
can be become exclusive at the first wrprotect fault.
This patch (of 22):
Add documentation.

sound updates for 4.3-rc1
There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-
related changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition
is for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It
was initiated by lockdep warning, but resulted in a good cleanup in
the end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP
USB-audio:
- Refactor runtime PM code to make lockdep happier

changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition is
for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It was
initiated by lockdep warning, but resulted in a good cleanup in the
end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP
USB-audio:
- Refactor runtime PM code to make lockdep happier"

[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
handled the conflict with the new Intel integrated IDMA driver by
slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
order to keep the Intel entries together. I think it might be a good
idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
the sorting be a true sort, not this mismash.
Also, this merge disables the COMPILE_TEST for the sun4i DMA
controller, because it does not compile cleanly at all. - Linus ]

This is the bulk of pin control changes for the v4.3 development
cycle
Core changes:
- It is possible configure groups in debugfs.
- Consolidation of chained IRQ handler install/remove replacing
all call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a
combined call to irq_set_chained_handler_and_data(). This
series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which
is way cleaner.
- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs
from IRQ numbers. The goal is to get rid of the irq number
from the handlers in the IRQ flow which is nice.
Driver feature enhancements:
- Power management support for the SiRF SoC Atlas 7.
- Power down support for the Qualcomm driver.
- Intel Cherryview and Baytrail: switch drivers to use raw
spinlocks in IRQ handlers to play nice with the realtime
patch set.
- Rework and new modes handling for Qualcomm SPMI-MPP.
- Pinconf power source config for SH PFC.
New drivers and subdrivers:
- A new driver for Conexant Digicolor CX92755.
- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
- Reverse-egineered the S/PDIF settings for the Allwinner
sun4i driver.
- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
- A new Freescale i.mx6ul subdriver.
Cleanup:
- Remove platform data support in a number of SH PFC
subdrivers.

This is the bulk of GPIO changes for the v4.3 kernel cycle:
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc
versions of the descriptor calls that did not use the flags
argument on the end. This was around for too long and eventually
Uwe Kleine-König took the time to clean it out and the last
users are removed along with the macros in this tag. In several
cases the use of flags simplifies the code. For this reason we
have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY
up until we hammer in the nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff
we have i the kernel to discourage people from reinventing
a square wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO
IRQ chip instead of using one class for all chips, as the current
code will not work with systems with several GPIO chips doing
lockdep debugging.
- Protect against driver unloading also when a GPIO line is only
used as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent
device driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing
all call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a
combined call to irq_set_chained_handler_and_data(). This
series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which
is way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs
from IRQ numbers. The goal is to get rid of the irq number
from the handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO
drivers. This was an ARM specific function that is replaced
with the generic irq_modify_status() where special flags
are actually needed.
- When an OF node has a pin range for its GPIOs, return
-EPROBE_DEFER if the pin controller isn't available.
Pretty logical, yet needed to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own
irq_*_resources call back, then call these instead of the
defaults provided by the GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not
properly documented.
Driver improvements:
- Add get_direction() support to the generic GPIO driver, it's
strange that we didn't have that before.
- Make it possible to have input-only GPIO chips using the
generic GPIO driver.
- Clean out platform data support from the Emma Mobile (EM)
driver
- Finegrained runtime PM support for the RCAR driver.
- Support r8a7795 (R-car H3) in the RCAR driver.
- Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
- Some consolidation and new support in the MPC8xxx driver,
we now support MPC5125.
- Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
spinlocks making it work better with the realime patches.
- Interrupt support for the EXTRAXFS GPIO driver.
- Make the ETRAXFS GPIO driver support also ARTPEC-3.
- Interrupt and wakeup support for the BRCMSTB driver, also for
wakeup from S5 cold boot.
- Mask MXC IRQs during suspend.
- Improve OMAP2 GPIO set_debounce() to work according to spec.
- The VF610 driver handles IRQs properly.
New drivers:
- ZTE ZX GPIO driver.

Merge tag 'gpio-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.3 kernel cycle.
There is quite a lot going on in the GPIO subsystem this merge window,
so the main matter is decribed below.
The hits in other subsystems when making the GPIO flags optional are
all ACKed by their respective subsystem maintainers.
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
of the descriptor calls that did not use the flags argument on the
end. This was around for too long and eventually Uwe Kleine-König
took the time to clean it out and the last users are removed along
with the macros in this tag. In several cases the use of flags
simplifies the code. For this reason we have (ACKed) patches
hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff we
have i the kernel to discourage people from reinventing a square
wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO IRQ
chip instead of using one class for all chips, as the current code
will not work with systems with several GPIO chips doing lockdep
debugging.
- Protect against driver unloading also when a GPIO line is only used
as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent device
driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data().
This series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO drivers.
This was an ARM specific function that is replaced with the generic
irq_modify_status() where special flags are actually needed.
- When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
if the pin controller isn't available. Pretty logical, yet needed
to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
back, then call these instead of the defaults provided by the
GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not properly
documented.
Driver improvements:
- Add get_direction() support to the generic GPIO driver, it's
strange that we didn't have that before.
- Make it possible to have input-only GPIO chips using the generic
GPIO driver.
- Clean out platform data support from the Emma Mobile (EM) driver
- Finegrained runtime PM support for the RCAR driver.
- Support r8a7795 (R-car H3) in the RCAR driver.
- Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
- Some consolidation and new support in the MPC8xxx driver, we now
support MPC5125.
- Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
spinlocks making it work better with the realime patches.
- Interrupt support for the EXTRAXFS GPIO driver.
- Make the ETRAXFS GPIO driver support also ARTPEC-3.
- Interrupt and wakeup support for the BRCMSTB driver, also for
wakeup from S5 cold boot.
- Mask MXC IRQs during suspend.
- Improve OMAP2 GPIO set_debounce() to work according to spec.
- The VF610 driver handles IRQs properly.
New drivers:
- ZTE ZX GPIO driver"

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"This is the main pull request for 4.3 for MIPS. Here's the summary:
Three fixes that didn't make 4.2-stable:
- a -Os build might compile the kernel using the MIPS16 instruction
set but the R2 optimized inline functions in <uapi/asm/swab.h> are
implemented using 32-bit wide instructions which is invalid.
- a build error in pgtable-bits.h for a particular kernel
configuration.
- accessing registers of the CM GCR might have been compiled to use
64 bit accesses but these registers are onl 32 bit wide.
And also a few new bits:
- move the ATH79 GPIO driver to drivers/gpio
- the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
change ATH79 accordingly.
- fix definition of pgprot_writecombine
- add an implementation of dma_map_ops.mmap
- fix alignment of quiet build output for vmlinuz link
- BCM47xx: Use kmemdup rather than duplicating its implementation
- Netlogic: Fix 0x0x prefixes of constants.
- merge Bjorn Helgaas' series to remove most of the weak keywords
from function declarations.
- CP0 and CP1 registers are best considered treated as unsigned
values to avoid large values from becoming negative values.
- improve support for the MIPS GIC timer.
- enable common clock framework for Malta and SEAD3.
- a number of improvments and fixes to dump_tlb().
- document the MIPS TLB dump functionality in Magic SysRq.
- Cavium Octeon CN68XX improvments.
- NetLogic improvments.
- irq: Use access helper irq_data_get_affinity_mask.
- handle MSA unaligned accesses.
- a number of R6-related math-emu fixes.
- support for I6400.
- improvments to MSA support.
- add uprobes support.
- move from deprecated __initcall to arch_initcall.
- remove finish_arch_switch().
- IRQ cleanups by Thomas Gleixner.
- migrate to new 'set-state' interface.
- random small cleanups"

Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking and atomic updates from Ingo Molnar:
"Main changes in this cycle are:
- Extend atomic primitives with coherent logic op primitives
(atomic_{or,and,xor}()) and deprecate the old partial APIs
(atomic_{set,clear}_mask())
The old ops were incoherent with incompatible signatures across
architectures and with incomplete support. Now every architecture
supports the primitives consistently (by Peter Zijlstra)
- Generic support for 'relaxed atomics':
- _acquire/release/relaxed() flavours of xchg(), cmpxchg() and {add,sub}_return()
- atomic_read_acquire()
- atomic_set_release()
This came out of porting qwrlock code to arm64 (by Will Deacon)
- Clean up the fragile static_key APIs that were causing repeat bugs,
by introducing a new one:
DEFINE_STATIC_KEY_TRUE(name);
DEFINE_STATIC_KEY_FALSE(name);
which define a key of different types with an initial true/false
value.
Then allow:
static_branch_likely()
static_branch_unlikely()
to take a key of either type and emit the right instruction for the
case. To be able to know the 'type' of the static key we encode it
in the jump entry (by Peter Zijlstra)
- Static key self-tests (by Jason Baron)
- qrwlock optimizations (by Waiman Long)
- small futex enhancements (by Davidlohr Bueso)
- ... and misc other changes"

Pull f2fs updates from Jaegeuk Kim: "The major work includes fixing and enhancing the existing extent_cache feature, which has been well settling down so far and now it becomes a default mount option accordingly. Also, this version newly registers a f2fs memory shrinker to reclaim several objects consumed by a couple of data structures in order to avoid memory pressures. Another new feature is to add ioctl(F2FS_GARBAGE_COLLECT) which triggers a cleaning job explicitly by users.

Pull networking updates from David Miller:
"Another merge window, another set of networking changes. I've heard
rumblings that the lightweight tunnels infrastructure has been voted
networking change of the year. But what do I know?
1) Add conntrack support to openvswitch, from Joe Stringer.
2) Initial support for VRF (Virtual Routing and Forwarding), which
allows the segmentation of routing paths without using multiple
devices. There are some semantic kinks to work out still, but
this is a reasonably strong foundation. From David Ahern.
3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov.
4) Ignore route nexthops with a link down state in ipv6, just like
ipv4. From Andy Gospodarek.
5) Remove spinlock from fast path of act_gact and act_mirred, from
Eric Dumazet.
6) Document the DSA layer, from Florian Fainelli.
7) Add netconsole support to bcmgenet, systemport, and DSA. Also
from Florian Fainelli.
8) Add Mellanox Switch Driver and core infrastructure, from Jiri
Pirko.
9) Add support for "light weight tunnels", which allow for
encapsulation and decapsulation without bearing the overhead of a
full blown netdevice. From Thomas Graf, Jiri Benc, and a cast of
others.
10) Add Identifier Locator Addressing support for ipv6, from Tom
Herbert.
11) Support fragmented SKBs in iwlwifi, from Johannes Berg.
12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia.
13) Add BQL support to 3c59x driver, from Loganaden Velvindron.
14) Stop using a zero TX queue length to mean that a device shouldn't
have a qdisc attached, use an explicit flag instead. From Phil
Sutter.
15) Use generic geneve netdevice infrastructure in openvswitch, from
Pravin B Shelar.
16) Add infrastructure to avoid re-forwarding a packet in software
that was already forwarded by a hardware switch. From Scott
Feldman.
17) Allow AF_PACKET fanout function to be implemented in a bpf
program, from Willem de Bruijn"

Pull device mapper update from Mike Snitzer: - a couple small cleanups in dm-cache, dm-verity, persistent-data's dm-btree, and DM core. - a 4.1-stable fix for dm-cache that fixes the leaking of deferred bio prison cells - a 4.2-stable fix that adds feature reporting for the dm-stats features added in 4.2 - improve DM-snapshot to not invalidate the on-disk snapshot if snapshot device write overflow occurs; but a write overflow triggered through the origin device will still invalidate the snapshot. - optimize DM-thinp's async discard submission a bit now that late bio splitting has been included in block core. - switch DM-cache's SMQ policy lock from using a mutex to a spinlock; improves performance on very low latency devices (eg. NVMe SSD). - document DM RAID 4/5/6's discard support [ I did not pull the slab changes, which weren't appropriate for this tree, and weren't obviously the right thing to do anyway. At the very least they need some discussion and explanation before getting merged.

Merge branch 'for-4.3/core' of git://git.kernel.dk/linux-block
Pull core block updates from Jens Axboe:
"This first core part of the block IO changes contains:
- Cleanup of the bio IO error signaling from Christoph. We used to
rely on the uptodate bit and passing around of an error, now we
store the error in the bio itself.
- Improvement of the above from myself, by shrinking the bio size
down again to fit in two cachelines on x86-64.
- Revert of the max_hw_sectors cap removal from a revision again,
from Jeff Moyer. This caused performance regressions in various
tests. Reinstate the limit, bump it to a more reasonable size
instead.
- Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.
Most devices have huge trim limits, which can cause nasty latencies
when deleting files. Enable the admin to configure the size down.
We will look into having a more sane default instead of UINT_MAX
sectors.
- Improvement of the SGP gaps logic from Keith Busch.
- Enable the block core to handle arbitrarily sized bios, which
enables a nice simplification of bio_add_page() (which is an IO hot
path). From Kent.
- Improvements to the partition io stats accounting, making it
faster. From Ming Lei.
- Also from Ming Lei, a basic fixup for overflow of the sysfs pending
file in blk-mq, as well as a fix for a blk-mq timeout race
condition.
- Ming Lin has been carrying Kents above mentioned patches forward
for a while, and testing them. Ming also did a few fixes around
that.
- Sasha Levin found and fixed a use-after-free problem introduced by
the bio->bi_error changes from Christoph.
- Small blk cgroup cleanup from Viresh Kumar"

Pull power management and ACPI updates from Rafael Wysocki:
"From the number of commits perspective, the biggest items are ACPICA
and cpufreq changes with the latter taking the lead (over 50 commits).
On the cpufreq front, there are many cleanups and minor fixes in the
core and governors, driver updates etc. We also have a new cpufreq
driver for Mediatek MT8173 chips.
ACPICA mostly updates its debug infrastructure and adds a number of
fixes and cleanups for a good measure.
The Operating Performance Points (OPP) framework is updated with new
DT bindings and support for them among other things.
We have a few updates of the generic power domains framework and a
reorganization of the ACPI device enumeration code and bus type
operations.
And a lot of fixes and cleanups all over.
Included is one branch from the MFD tree as it contains some
PM-related driver core and ACPI PM changes a few other commits are
based on.
Specifics:
- ACPICA update to upstream revision 20150818 including method
tracing extensions to allow more in-depth AML debugging in the
kernel and a number of assorted fixes and cleanups (Bob Moore, Lv
Zheng, Markus Elfring).
- ACPI sysfs code updates and a documentation update related to AML
method tracing (Lv Zheng).
- ACPI EC driver fix related to serialized evaluations of _Qxx
methods and ACPI tools updates allowing the EC userspace tool to be
built from the kernel source (Lv Zheng).
- ACPI processor driver updates preparing it for future introduction
of CPPC support and ACPI PCC mailbox driver updates (Ashwin
Chaugule).
- ACPI interrupts enumeration fix for a regression related to the
handling of IRQ attribute conflicts between MADT and the ACPI
namespace (Jiang Liu).
- Fixes related to ACPI device PM (Mika Westerberg, Srinidhi
Kasagar).
- ACPI device registration code reorganization to separate the
sysfs-related code and bus type operations from the rest (Rafael J
Wysocki).
- Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause,
Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss).
- ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan
Xinhui, Rafael J Wysocki).
- cpufreq core cleanups on top of the previous changes allowing it to
preseve its sysfs directories over system suspend/resume (Viresh
Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior).
- cpufreq fixes and cleanups related to governors (Viresh Kumar).
- cpufreq updates (core and the cpufreq-dt driver) related to the
turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz).
- New DT bindings for Operating Performance Points (OPP), support for
them in the OPP framework and in the cpufreq-dt driver plus related
OPP framework fixes and cleanups (Viresh Kumar).
- cpufreq powernv driver updates (Shilpasri G Bhat).
- New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen).
- Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups
and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean).
- intel_pstate driver updates including Skylake-S support, support
for enabling HW P-states per CPU and an additional vendor bypass
list entry (Kristen Carlson Accardi, Chen Yu, Ethan Zhao).
- cpuidle core fixes related to the handling of coupled idle states
(Xunlei Pang).
- intel_idle driver updates including Skylake Client support and
support for freeze-mode-specific idle states (Len Brown).
- Driver core updates related to power management (Andy Shevchenko,
Rafael J Wysocki).
- Generic power domains framework fixes and cleanups (Jon Hunter,
Geert Uytterhoeven, Rajendra Nayak, Ulf Hansson).
- Device PM QoS framework update to allow the latency tolerance
setting to be exposed to user space via sysfs (Mika Westerberg).
- devfreq support for PPMUv2 in Exynos5433 and a fix for an incorrect
exynos-ppmu DT binding (Chanwoo Choi, Javier Martinez Canillas).
- System sleep support updates (Alan Stern, Len Brown, SungEun Kim).
- rockchip-io AVS support updates (Heiko Stuebner).
- PM core clocks support fixup (Colin Ian King).
- Power capping RAPL driver update including support for Skylake H/S
and Broadwell-H (Radivoje Jovanovic, Seiichi Ikarashi).
- Generic device properties framework fixes related to the handling
of static (driver-provided) property sets (Andy Shevchenko).
- turbostat and cpupower updates (Len Brown, Shilpasri G Bhat,
Shreyas B Prabhu)"
