def5efe037 mm, madvise: fail with ENOMEM when splitting vma will hit max_map_count 
If madvise(2) advice will result in the underlying vma being split and
the number of areas mapped by the process will exceed
/proc/sys/vm/max_map_count as a result, return ENOMEM instead of EAGAIN.

EAGAIN is returned by madvise(2) when a kernel resource, such as slab,
is temporarily unavailable.  It indicates that userspace should retry
the advice in the near future.  This is important for advice such as
MADV_DONTNEED which is often used by malloc implementations to free
memory back to the system: we really do want to free memory back when
madvise(2) returns EAGAIN because slab allocations (for vmas, anon_vmas,
or mempolicies) cannot be allocated.

Encountering /proc/sys/vm/max_map_count is not a temporary failure,
however, so return ENOMEM to indicate this is a more serious issue.  A
followup patch to the man page will specify this behavior.

e86c59b1b1 mm/ksm: improve deduplication of zero pages with colouring 
Some architectures have a set of zero pages (coloured zero pages)
instead of only one zero page, in order to improve the cache
performance.  In those cases, the kernel samepage merger (KSM) would
merge all the allocated pages that happen to be filled with zeroes to
the same deduplicated page, thus losing all the advantages of coloured
zero pages.

This behaviour is noticeable when a process accesses large arrays of
allocated pages containing zeroes.  A test I conducted on s390 shows
that there is a speed penalty when KSM merges such pages, compared to
not merging them or using actual zero pages from the start without
breaking the COW.

This patch fixes this behaviour.  When coloured zero pages are present,
the checksum of a zero page is calculated during initialisation, and
compared with the checksum of the current canditate during merging.  In
case of a match, the normal merging routine is used to merge the page
with the correct coloured zero page, which ensures the candidate page is
checked to be equal to the target zero page.

A sysfs entry is also added to toggle this behaviour, since it can
potentially introduce performance regressions, especially on
architectures without coloured zero pages.  The default value is
disabled, for backwards compatibility.

With this patch, the performance with KSM is the same as with non
COW-broken actual zero pages, which is also the same as without KSM.

Merge tag 'drm-for-v4.11-less-shouty' of git://people.freedesktop.org/~airlied/linux

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.11.

  Nothing too major, the tinydrm and mmu-less support should make
  writing smaller drivers easier for some of the simpler platforms, and
  there are a bunch of documentation updates.

  Intel grew displayport MST audio support which is hopefully useful to
  people, and FBC is on by default for GEN9+ (so people know where to
  look for regressions). AMDGPU has a lot of fixes that would like new
  firmware files installed for some GPUs.

  Other than that it's pretty scattered all over.

  I may have a follow up pull request as I know BenH has a bunch of AST
  rework and fixes and I'd like to get those in once they've been tested

   - The GIC memory map was a bit wrong almost everywhere and now
     gets fixed up
   - The Allwinner platforms convert to the generic pinmux properties
   - The Marvell EBU platforms now use the new DSA binding
   - Samsung Exynos4212 was unused and gets removed
   - The Renesas power management got improved

6ae52c65e0 ARM: SoC platform updates 
In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
 C code changes for SoC platforms. This release cycle the diffstat is quite
 nice, in that we're removing 3x the amount of code that's being added.
 
 The main reason for this is that there's a removal of camera drivers for
 Freescale i.MX chips (driver was removed so the device registration isn't
 needed any more). There's also removal of display initialization code for OMAP
 that is no longer needed.
 
 The rest are mostly minor tweaks and cleanups; constification on Samsung
 platforms, cleanup of ux500 platform data, purge of other unused platform
 data/device seutp on i.MX and other good stuff.
 
 New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

a3919caaa2 remoteproc updates for v4.11 
This introduces support for booting the dedicated sensor core in the
 Qualcomm MSM8996, updates the Qualcomm ADSP and Hexagon drivers to
 utilize SMD subdevice helpers for properly handle shutdowns and restarts
 of the remoteproc, add virtio support to the ST remoteproc and refactor
 the Qualcomm Hexagon driver to handle variations between platforms.
 
 The support code for parsing, loading and authenticating Qualcomm
 firmware files (MDT) is refactored and move to drivers/soc/qcom, to
 allow for non-remoteproc drivers to utilize this.
 
 Finally it brings some cleanups to the remoteproc core.

1ec5c1867a This is the bulk of GPIO changes for the v4.11 cycle 
Core changes:
 
 - Augment fwnode_get_named_gpiod() to configure the GPIO pin
   immediately after requesting it like all other APIs do.
   This is a treewide change also updating all users.
 
 - Pass a GPIO label down to gpiod_request() from
   fwnode_get_named_gpiod(). This makes debugfs and the userspace
   ABI correctly reflect the current in-kernel consumer of a pin
   taken using this abstraction. This is a treewide change also
   updating all users.
 
 - Rename devm_get_gpiod_from_child() to
   devm_fwnode_get_gpiod_from_child() to reflect the fact that this
   function is operating on a fwnode object. This is a treewide
   change also updating all users.
 
 - Make it possible to take multiple GPIOs in a single hog of device
   tree hogs.
 
 - The refactorings switching GPIO chips to use the .set_config()
   callback using standard pin control properties and providing
   a backend into the pin control subsystem that were also merged
   into the pin control tree naturally appear here too.
 
 Testing instrumentation:
 
 - A whole slew of cleanups and improvements to the mockup GPIO
   driver. We now have an extended userspace test exercising the
   subsystem, and we can inject interrupts etc from userspace
   to fully test the core GPIO functionality.
 
 New drivers:
 
 - New driver for the Cortina Systems Gemini GPIO controller.
 
 - New driver for the Exar XR17V352/354/358 chips.
 
 - New driver for the ACCES PCI-IDIO-16 PCI GPIO card.
 
 Driver changes:
 
 - RCAR: set the irqchip parent device, add fine-grained runtime
   PM support.
 
 - pca953x: support optional RESET control line on the chip.
 
 - DaVinci: cleanups and simplifications. Add support for multiple
   instances.
 
 - .set_multiple() and naming of lines on more or less all of the
   ISA/PCI GPIO controllers.
 
 - mcp23s08: refactored to use regmap as a first step to further
   rewrites and modernizations.

c87d1655c2 zram: remove obsolete sysfs attrs 
We had a deprecated_attr_warn() warning for 2 years and now the time has
come and we finally can do the cleanup.

The plan was as follows:

: per-stat sysfs attributes are considered to be deprecated.
: The basic strategy is:
: -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11)
: -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11)
:
: The list of deprecated attributes can be found here:
: Documentation/ABI/obsolete/sysfs-block-zram
:
: Basically, every attribute that has its own read accessible sysfs
: node (e.g. num_reads) *AND* is accessible via one of the stat files
: (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered
: to be deprecated.

The patch also removes `obsolete/sysfs-block-zram', clean ups
`testing/sysfs-block-zram' and tweaks zram.txt files.

21440d7eb9 mm, thp: add new defer+madvise defrag option 
There is no thp defrag option that currently allows MADV_HUGEPAGE
regions to do direct compaction and reclaim while all other thp
allocations simply trigger kswapd and kcompactd in the background and
fail immediately.

The "defer" setting simply triggers background reclaim and compaction
for all regions, regardless of MADV_HUGEPAGE, which makes it unusable
for our userspace where MADV_HUGEPAGE is being used to indicate the
application is willing to wait for work for thp memory to be available.

The "madvise" setting will do direct compaction and reclaim for these
MADV_HUGEPAGE regions, but does not trigger kswapd and kcompactd in the
background for anybody else.

For reasonable usage, there needs to be a mesh between the two options.
This patch introduces a fifth mode, "defer+madvise", that will do direct
reclaim and compaction for MADV_HUGEPAGE regions and trigger background
reclaim and compaction for everybody else so that hugepages may be
available in the near future.

A proposal to allow direct reclaim and compaction for MADV_HUGEPAGE
regions as part of the "defer" mode, making it a very powerful setting
and avoids breaking userspace, was offered:
     http://marc.info/?t=148236612700003
This additional mode is a compromise.

A second proposal to allow both "defer" and "madvise" to be selected at
the same time was also offered:
     http://marc.info/?t=148357345300001.
This is possible, but there was a concern that it might break existing
userspaces the parse the output of the defrag mode, so the fifth option
was introduced instead.

This patch also cleans up the helper function for storing to "enabled"
and "defrag" since the former supports three modes while the latter
supports five and triple_flag_store() was getting unnecessarily messy.

1663f26df3 slub: make sysfs directories for memcg sub-caches optional 
SLUB creates a per-cache directory under /sys/kernel/slab which hosts a
bunch of debug files.  Usually, there aren't that many caches on a
system and this doesn't really matter; however, if memcg is in use, each
cache can have per-cgroup sub-caches.  SLUB creates the same directories
for these sub-caches under /sys/kernel/slab/$CACHE/cgroup.

Unfortunately, because there can be a lot of cgroups, active or
draining, the product of the numbers of caches, cgroups and files in
each directory can reach a very high number - hundreds of thousands is
commonplace.  Millions and beyond aren't difficult to reach either.

What's under /sys/kernel/slab is primarily for debugging and the
information and control on the a root cache already cover its
sub-caches.  While having a separate directory for each sub-cache can be
helpful for development, it doesn't make much sense to pay this amount
of overhead by default.

This patch introduces a boot parameter slub_memcg_sysfs which determines
whether to create sysfs directories for per-memcg sub-caches.  It also
adds CONFIG_SLUB_MEMCG_SYSFS_ON which determines the boot parameter's
default value and defaults to 0.

37c85961c3 TTY/Serial driver patches for 4.11-rc1 
Here is the big tty/serial driver patchset for 4.11-rc1.
 
 Not much here, but a lot of little fixes and individual serial driver
 updates all over the subsystem.  Majority are for the sh-sci driver and
 platform (the arch-specific changes have acks from the maintainer).
 
 The start of the "serial bus" code is here as well, but nothing is
 converted to use it yet.  That work is still ongoing, hopefully will
 start to show up across different subsystems for 4.12 (bluetooth is one
 major place that will be used.)
 
 All of these have been in linux-next for a while with no reported
 issues.

38705613b7 powerpc updates for 4.11 part 1. 
Highlights include:
 
  - Support for direct mapped LPC on POWER9, giving Linux direct access to
    devices that may be on there such as a UART.
 
  - Memory hotplug support for the Power9 Radix MMU.
 
  - Add new AUX vectors describing the processor's cache geometry, to be used by
    glibc.
 
  - The ability for a guest to ask the hypervisor to resize the guest's hash
    table, and in addition support for doing so automatically when memory is
    hotplugged into/out-of the guest. This allows the hash table to be sized
    based on the current memory usage of the guest, rather than the maximum
    possible memory usage.
 
  - Implementation of optprobes (kprobe optimisation) for powerpc.
 
 In addition there's the topic branch shared with the KVM tree, which includes
 support for guests to use the Radix MMU on Power9.

     hash table, and in addition support for doing so automatically when
     memory is hotplugged into/out-of the guest. This allows the hash
     table to be sized based on the current memory usage of the guest,
     rather than the maximum possible memory usage.

   - Implementation of optprobes (kprobe optimisation) for powerpc.

  In addition there's the topic branch shared with the KVM tree, which
  includes support for guests to use the Radix MMU on Power9.

5ab356626f Pin control bulk changes for the v4.11 kernel cycle: 
Core changes:
 
 - Switch the generic pin config argument from 16 to 24 bits,
   only use 8 bits for the configuration type. We might need to
   encode more information about a certain setting than we need
   to encode different generic settings.
 
 - Add a cross-talk API to the pin control GPIO back-end,
   utilizing pinctrl_gpio_set_config() from GPIO drivers that
   want to set up a certain pin configuration in the back-end.
   This also includes the .set_config() refactoring of the
   GPIO chips, so that they pass a generic configuration for
   things like debouncing and single ended (typically open
   drain). This change has also been merged in an immutable
   branch to the GPIO tree.
 
 - Take hogs with a delayed work, so that we finalize probing
   a pin controller before trying to get any hogs.
 
 - For pin controllers putting all group and function definitions
   into the device tree, we now have generic code to deal with
   this and it is used in two drivers so far.
 
 - Simplifications of the pin request conflict check.
 
 - Make dt_free_map() optional.
 
 Updates to drivers:
 
 - pinctrl-single now use the generic helpers to generate dynamic
   group and function tables from the device tree.
 
 - Texas Instruments IOdelay configuration driver add-on to
   pinctrl-single.
 
 - i.MX: use radix trees to store groups and functions, use the new
   generic group and function helpers to manage them.
 
 - Intel: add support for hardware debouncing and 1K pull-down.
   New subdriver for the Gemini Lake SoC.
 
 - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
   MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
 
 - Aspeed: use syscon cross-dependencies to set up related bits in
   the LPC host controller and display controller.
 
 - Aspeed: finalize G4 and G5 support. Fix mux configuration on
   GPIOs. Add banks Y, Z, AA, AB and AC.
 
 - AMD: support additional GPIO.
 
 - STM32: set this controller to strict muxing mode.
   STM32H743 MCU support.
 
 - Allwinner sunxi: deep simplifications on how to support
   subvariants of SoCs without adding to much SoC-specific data
   for each subvariant, especially for sun5i variants. New driver
   for V3s SoCs. New driver for the H5 SoC. Support A31/A31s
   variants with the new variant framework.
 
 - Mvebu: simplifications to use a MMIO and regmap abstraction.
   New subdrivers for the 98DX3236, 98DX5241 SoCs.
 
 - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the
   SoC driver to access regmaps. Add infrastructure for pin-bank
   retention control. Clean out the pin retention control from
   arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly
   in the Samsung pin control driver(s).
 
 - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
 
 - Qualcomm: use raw spinlock variants: this makes the qualcomm
   driver realtime-safe.

7a771ceac7 - Fix dm-raid transient device failure processing and other smaller 
tweaks.
 
 - Add journal support to the DM raid target to close the 'write hole' on
   raid 4/5/6.
 
 - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB.
 
 - Add 'metadata2' feature to dm-cache to separate the dirty bitset out
   from other cache metadata.  This improves speed of shutting down
   a large cache device (which implies writing out dirty bits).
 
 - Fix a memory leak during dm-stats data structure destruction.
 
 - Fix a DM multipath round-robin path selector performance regression
   that was caused by less precise balancing across all paths.
 
 - Lastly, introduce a DM core fix for a long-standing DM snapshot
   deadlock that is rooted in the complexity of the device stack used in
   conjunction with block core maintaining bios on current->bio_list to
   manage recursion in generic_make_request().  A more comprehensive fix
   to block core (and its hook in the cpu scheduler) would be wonderful
   but this DM-specific fix is pragmatic considering how difficult it has
   been to make progress on a generic fix.
