Linus Torvalds e2464688b5 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 MIPS for 4.5 plus some 4.4 fixes.

  The executive summary:

   - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
   - Avoid useless rebuilds for zboot.
   - jz4780: Add NEMC, BCH and NAND device tree nodes
   - Initial support for the MicroChip's DT platform.  As all the device
     drivers are missing this is still of limited use.
   - Some Loongson3 cleanups.
   - The unavoidable whitespace polishing.
   - Reduce clock skew when synchronizing the CPU cycle counters on CPU
     startup.
   - Add MIPS R6 fixes.
   - Lots of cleanups across arch/mips as fallout from KVM.
   - Lots of minor fixes and changes for IEEE 754-2008 support to the
     FPU emulator / fp-assist software.
   - Minor Ralink, BCM47xx and bcm963xx platform support improvments.
   - Support SMP on BCM63168"

Linus Torvalds 9638685e32 ARM: SoC driver updates for v4.5
Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc,
 but also some other driver updates that don't belong anywhere else. We also
 bring in the drivers/reset code through arm-soc.
 
 Some of the larger updates:
 
 - Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
   parts of the chip/board on these platforms, all proprietary protocols that
   don't fit into other subsystems and live in drivers/soc for now.
 
 - System bus driver for UniPhier
 - Driver for the TI Wakeup M3 IPC device
 
 - Power management for Raspberry PI

Linus Torvalds 6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

Linus Torvalds 6b5a12dbca ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6
 and ARMv7 platforms together such that they can all be enabled and
 boot the same kernel. It has been a tremendous amount of cleanup and
 refactoring by a huge number of people, and creation of several new
 (and major) subsystems to better abstract out all the platform details
 in an appropriate manner.
 
 The bulk of this branch is a large patchset from Arnd that brings several
 of the more minor and older platforms we have closer to multiplatform
 support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
 Much of this is moving around header files from old mach directories,
 but there are also some cleanup patches of debug_ll (lowlevel debug
 per-platform options) and other parts.
 
 Linus Walleij also has some patchs to clean up the older ARM Realview
 platforms by finally introducing DT support, and Rob Herring has some
 for ARM Versatile which is now DT-only. Both of these platforms are
 now multiplatform.
 
 Finally, a couple of patches from Russell for Dove PMU, and a fix from
 Valentin Rothberg for Exynos ADC, which were rebased on top of the
 series to avoid conflicts.

Andrey Ryabinin c6d308534a UBSAN: run-time undefined behavior sanity checker
UBSAN uses compile-time instrumentation to catch undefined behavior
(UB).  Compiler inserts code that perform certain kinds of checks before
operations that could cause UB.  If check fails (i.e.  UB detected)
__ubsan_handle_* function called to print error message.

So the most of the work is done by compiler.  This patch just implements
ubsan handlers printing errors.

GCC has this capability since 4.9.x [1] (see -fsanitize=undefined
option and its suboptions).
However GCC 5.x has more checkers implemented [2].
Article [3] has a bit more details about UBSAN in the GCC.

[1] - https://gcc.gnu.org/onlinedocs/gcc-4.9.0/gcc/Debugging-Options.html
[2] - https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html
[3] - http://developerblog.redhat.com/2014/10/16/gcc-undefined-behavior-sanitizer-ubsan/

Issues which UBSAN has found thus far are:

Found bugs:

 * out-of-bounds access - 97840cb67f ("netfilter: nfnetlink: fix
   insufficient validation in nfnetlink_bind")

undefined shifts:

SYSCTL_WRITES_WARN was added in commit f4aacea2f5 ("sysctl: allow for

2014.  Since then I can find only 1 instance of non-zero offset
writing[1], and it was fixed immediately in CRIU[2].  As such, it
appears safe to flip this to the strict state now.

Willy Tarreau 759c01142a pipe: limit the per-user amount of pages allocated in pipes
On no-so-small systems, it is possible for a single process to cause an
OOM condition by filling large pipes with data that are never read. A
typical process filling 4000 pipes with 1 MB of data will use 4 GB of
memory. On small systems it may be tricky to set the pipe max size to
prevent this from happening.

This patch makes it possible to enforce a per-user soft limit above
which new pipes will be limited to a single page, effectively limiting
them to 4 kB each, as well as a hard limit above which no new pipes may
be created for this user. This has the effect of protecting the system
against memory abuse without hurting other users, and still allowing
pipes to work correctly though with less data at once.

The limit are controlled by two new sysctls : pipe-user-pages-soft, and
pipe-user-pages-hard. Both may be disabled by setting them to zero. The
default soft limit allows the default number of FDs per process (1024)
to create pipes of the default size (64kB), thus reaching a limit of 64MB
before starting to create only smaller pipes. With 256 processes limited
to 1024 FDs each, this results in 1024*64kB + (256*1024 - 1024) * 4kB =
1084 MB of memory allocated for a user. The hard limit is disabled by
default to avoid breaking existing applications that make intensive use
of pipes (eg: for splicing).

Maciej W. Rozycki 503943e0e5 MIPS: Add IEEE Std 754 conformance mode selection
Add an `ieee754=' kernel parameter to control IEEE Std 754 conformance
mode.

Use separate flags copied from the respective CPU feature flags, and
adjusted according to the conformance mode selected, to make binaries
requesting individual NaN encoding modes accepted or rejected as needed.
Update the initial setting for FCSR and, in the full FPU emulation mode,
its read-only mask accordingly.  Accept the mode selection requested for
legacy processors as well.

As with the EF_MIPS_NAN2008 ELF file header flag adjust both ABS2008 and
NAN2008 bits at the same time, to match the choice made for hardware
currently implemented.

Linus Torvalds d43fb9f3c5 fbdev changes for 4.5
* pxafb: device-tree support
 * An unsafe kernel parameter 'lockless_register_fb' for debugging problems
   happening while inside the console lock
 * Small miscellaneous fixes & cleanups
 * omapdss: add writeback support functions
 * Separation of omapfb and omapdrm (see below)
 
 About the separation of omapfb and omapdrm, see
 http://permalink.gmane.org/gmane.comp.video.dri.devel/143151 for longer story.
 
 The short version:
 
 omapfb and omapdrm have shared low level drivers (omapdss and panel drivers),
 making further development of omapdrm difficult. After these patches omapfb and
 omapdrm have their own versions of the drivers, which are more or less
 direct copies for now but will diverge soon.
 
 This also means that omapfb (everything under drivers/video/fbdev/omap2/) is
 now in maintenance mode, and all new development will be done for omapdrm
 (drivers/gpu/drm/omapdrm/).

Simon Horman 6bf641039f dmaengine: rcar-dmac: Document SoC specific bindings
In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas R-Car DMA Controller driver to follow this convention.

Linus Torvalds 58cf279aca GPIO bulk updates for the v4.5 kernel cycle:
Infrastructural changes:
 
 - In struct gpio_chip, rename the .dev node to .parent to better reflect
   the fact that this is not the GPIO struct device abstraction. We will
   add that soon so this would be totallt confusing.
 
 - It was noted that the driver .get_value() callbacks was
   sometimes reporting negative -ERR values to the gpiolib core, expecting
   them to be propagated to consumer gpiod_get_value() and gpio_get_value()
   calls. This was not happening, so as there was a mess of drivers
   returning negative errors and some returning "anything else than zero"
   to indicate that a line was active. As some would have bit 31 set to
   indicate "line active" it clashed with negative error codes. This is
   fixed by the largeish series clamping values in all drivers with
   !!value to [0,1] and then augmenting the code to propagate error codes
   to consumers. (Includes some ACKed patches in other subsystems.)
 
 - Add a void *data pointer to struct gpio_chip. The container_of() design
   pattern is indeed very nice, but we want to reform the struct gpio_chip
   to be a non-volative, stateless business, and keep states internal to
   the gpiolib to be able to hold on to the state when adding a proper
   userspace ABI (character device) further down the road. To achieve this,
   drivers need a handle at the internal state that is not dependent on
   their struct gpio_chip() so we add gpiochip_add_data() and
   gpiochip_get_data() following the pattern of many other subsystems.
   All the "use gpiochip data pointer" patches transforms drivers to this
   scheme.
 
 - The Generic GPIO chip header has been merged into the general
   <linux/gpio/driver.h> header, and the custom header for that removed.
   Instead of having a separate mm_gpio_chip struct for these generic
   drivers, merge that into struct gpio_chip, simplifying the code and
   removing the need for separate and confusing includes.
 
 Misc improvements:
 
 - Stabilize the way GPIOs are looked up from the ACPI legacy
   specification.
 
 - Incremental driver features for PXA, PCA953X, Lantiq (patches from the
   OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
 
 New drivers:
 
 - Add a GPIO chip to the ALSA SoC AC97 driver.
 
 - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
   the branch is merged here too to account for infrastructural changes).
 
 - The sx150x driver now supports the sx1502.

Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "Here is the bulk of GPIO changes for v4.5.

  Notably there are big refactorings mostly by myself, aimed at getting
  the gpio_chip into a shape that makes me believe I can proceed to
  preserve state for a proper userspace ABI (character device) that has
  already been proposed once, but resulted in the feedback that I need
  to go back and restructure stuff.  So I've been restructuring stuff.
  On the way I ran into brokenness (return code from the get_value()
  callback) and had to fix it.  Also, refactored generic GPIO to be
  simpler.

  Some of that is still waiting to trickle down from the subsystems all
  over the kernel that provide random gpio_chips, I've touched every
  single GPIO driver in the kernel now, oh man I didn't know I was
  responsible for so much...

  Apart from that we're churning along as usual.

  I took some effort to test and retest so it should merge nicely and we
  shook out a couple of bugs in -next.

  Infrastructural changes:

   - In struct gpio_chip, rename the .dev node to .parent to better
     reflect the fact that this is not the GPIO struct device
     abstraction.  We will add that soon so this would be totallt
     confusing.

   - It was noted that the driver .get_value() callbacks was sometimes
     reporting negative -ERR values to the gpiolib core, expecting them
     to be propagated to consumer gpiod_get_value() and gpio_get_value()
     calls.  This was not happening, so as there was a mess of drivers
     returning negative errors and some returning "anything else than
     zero" to indicate that a line was active.  As some would have bit
     31 set to indicate "line active" it clashed with negative error
     codes.  This is fixed by the largeish series clamping values in all
     drivers with !!value to [0,1] and then augmenting the code to
     propagate error codes to consumers.  (Includes some ACKed patches
     in other subsystems.)

   - Add a void *data pointer to struct gpio_chip.  The container_of()
     design pattern is indeed very nice, but we want to reform the
     struct gpio_chip to be a non-volative, stateless business, and keep
     states internal to the gpiolib to be able to hold on to the state
     when adding a proper userspace ABI (character device) further down
     the road.  To achieve this, drivers need a handle at the internal
     state that is not dependent on their struct gpio_chip() so we add
     gpiochip_add_data() and gpiochip_get_data() following the pattern
     of many other subsystems.  All the "use gpiochip data pointer"
     patches transforms drivers to this scheme.

   - The Generic GPIO chip header has been merged into the general
     <linux/gpio/driver.h> header, and the custom header for that
     removed.  Instead of having a separate mm_gpio_chip struct for
     these generic drivers, merge that into struct gpio_chip,
     simplifying the code and removing the need for separate and
     confusing includes.

  Misc improvements:

   - Stabilize the way GPIOs are looked up from the ACPI legacy
     specification.

   - Incremental driver features for PXA, PCA953X, Lantiq (patches from
     the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48

  New drivers:

   - Add a GPIO chip to the ALSA SoC AC97 driver.

   - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
     but the branch is merged here too to account for infrastructural
     changes).

   - The sx150x driver now supports the sx1502"

Linus Torvalds a016af2e70 sound updates for 4.5-rc1
We've had quite busy weeks in this cycle.  Looking at ALSA core, the
 significant changes are a few fixes wrt timer and sequencer ioctls
 that have been revealed by fuzzer recently.  Other than that, ASoC
 core got a few updates about DAI link handling, but these are rather
 straightforward refactoring.
 
 In drivers scene, ASoC received quite lots of new drivers in addition
 to bunch of updates for still ongoing Intel Skylake support and
 topology API.  HD-audio gained a new HDMI/DP hotplug notification via
 component.  FireWire got a pile of code refactoring/updates with
 SCS.1x driver integration.
 
 More highlights are shown below.
 
 [NOTE: this contains also many commits for DRM.  This is due to the
  pull of drm stable branch into sound tree, as the base of i915 audio
  component work for HD-audio.  The highlights below don't contain
  these DRM changes, as these are supposed to be pulled via drm tree in
  anyway sooner or later.]
 
 Core
  - Handful fixes to harden ALSA timer and sequencer ioctls against
    races reported by syzkaller fuzzer
  - Irq description string can be unique to each card; only for
    HD-audio for now
 
 ASoC
  - Conversion of the array of DAI links to a list for supporting
    dynamically adding and removing DAI links
  - Topology API enhancements to make everything more component based
    and being able to specify PCM links via topology
  - Some more fixes for the topology code, though it is still not final
    and ready for enabling in production; we really need to get to the
    point where that can be done
  - A pile of changes for Intel SkyLake drivers which hopefully deliver
    some useful initial functionality for systems with this chipset,
    though there is more work still to come
  - Lots of new features and cleanups for the Renesas drivers
  - ANC support for WM5110
  - New drivers: Imagination Technologies IPs, Atmel class D speaker,
    Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
    RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
  - Rename PCM1792a driver to be generic pcm179x
 
 HD-Audio
  - Use audio component for i915 HDMI/DP hotplug handling
  - On-demand binding with i915 driver
  - bdl_pos_adj parameter adjustment for Baytrail controllers
  - Enable power_save_node for CX20722; this shouldn't lead to
    regression, hopefully
  - Kabylake HDMI/DP codec support
  - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
    machines
  - A few code refactoring
 
 FireWire
  - Lots of code cleanup and refactoring
  - Integrate the support of SCS.1x devices into snd-oxfw driver;
    snd-scs1x driver is obsoleted
 
 USB-audio
  - Fix possible NULL dereference at disconnection
  - A regression fix for Native Instruments devices
 
 Misc
  - A few code cleanups of fm801 driver

Linus Torvalds ece6267878 The clk framework and driver changes for 4.5 look pretty typical. The
bulk of the changes are to clk controller drivers, though some
 improvements to the core and some re-usable blocks/templates also
 received some love. In this past cycle the clk maintainers developed a
 good workflow for handling the common case of patch submissions
 containing a new drivers, new shared Device Tree header and a new Device
 Tree binding description. This requires coordination with the Device
 Tree maintainers and with the architecture maintainers (typically the
 arm-soc tree in our case). This explains the increase in changes to
 include/dt-bindings/... and to
 Documentation/devicetree/bindings/clock/... coming from the clk tree.
 The same commits can be expected to come through those trees on
 occasion, through the use of shared, immutable branches.

  In this past cycle the clk maintainers developed a good workflow for
  handling the common case of patch submissions containing a new
  drivers, new shared Device Tree header and a new Device Tree binding
  description.  This requires coordination with the Device Tree
  maintainers and with the architecture maintainers (typically the
  arm-soc tree in our case).

  This explains the increase in changes to include/dt-bindings/... and
  to Documentation/devicetree/bindings/clock/... coming from the clk
  tree.  The same commits can be expected to come through those trees on
  occasion, through the use of shared, immutable branches"

Johannes Weiner f7e1cb6ec5 mm: memcontrol: account socket memory in unified hierarchy memory controller
Socket memory can be a significant share of overall memory consumed by
common workloads.  In order to provide reasonable resource isolation in
the unified hierarchy, this type of memory needs to be included in the
tracking/accounting of a cgroup under active memory resource control.

Overhead is only incurred when a non-root control group is created AND
the memory controller is instructed to track and account the memory
footprint of that group.  cgroup.memory=nosocket can be specified on the
boot commandline to override any runtime configuration and forcibly
exclude socket memory from active memory resource control.

Daniel Cashman d07e22597d mm: mmap: add new /proc tunable for mmap_base ASLR
Address Space Layout Randomization (ASLR) provides a barrier to
exploitation of user-space processes in the presence of security
vulnerabilities by making it more difficult to find desired code/data
which could help an attack.  This is done by adding a random offset to
the location of regions in the process address space, with a greater
range of potential offset values corresponding to better protection/a
larger search-space for brute force, but also to greater potential for
fragmentation.

The offset added to the mmap_base address, which provides the basis for
the majority of the mappings for a process, is set once on process exec
in arch_pick_mmap_layout() and is done via hard-coded per-arch values,
which reflect, hopefully, the best compromise for all systems.  The
trade-off between increased entropy in the offset value generation and
the corresponding increased variability in address space fragmentation
is not absolute, however, and some platforms may tolerate higher amounts
of entropy.  This patch introduces both new Kconfig values and a sysctl
interface which may be used to change the amount of entropy used for
offset generation on a system.

The direct motivation for this change was in response to the
libstagefright vulnerabilities that affected Android, specifically to
information provided by Google's project zero at:

  http://googleprojectzero.blogspot.com/2015/09/stagefrightened.html

The attack presented therein, by Google's project zero, specifically
targeted the limited randomness used to generate the offset added to the
mmap_base address in order to craft a brute-force-based attack.
Concretely, the attack was against the mediaserver process, which was
limited to respawning every 5 seconds, on an arm device.  The hard-coded
8 bits used resulted in an average expected success rate of defeating
the mmap ASLR after just over 10 minutes (128 tries at 5 seconds a
piece).  With this patch, and an accompanying increase in the entropy
value to 16 bits, the same attack would take an average expected time of
over 45 hours (32768 tries), which makes it both less feasible and more
likely to be noticed.

The introduced Kconfig and sysctl options are limited by per-arch
minimum and maximum values, the minimum of which was chosen to match the
current hard-coded value and the maximum of which was chosen so as to
give the greatest flexibility without generating an invalid mmap_base
address, generally a 3-4 bits less than the number of bits in the
user-space accessible virtual address space.

When decided whether or not to change the default value, a system
developer should consider that mmap_base address could be placed
anywhere up to 2^(value) bits away from the non-randomized location,
which would introduce variable-sized areas above and below the mmap_base
address such that the maximum vm_area_struct size may be reduced,
preventing very large allocations.

This patch (of 4):

ASLR only uses as few as 8 bits to generate the random offset for the
mmap base address on 32 bit architectures.  This value was chosen to
prevent a poorly chosen value from dividing the address space in such a
way as to prevent large allocations.  This may not be an issue on all
platforms.  Allow the specification of a minimum number of bits so that
platforms desiring greater ASLR protection may determine where to place
the trade-off.

Jerome Marchand 8cee852ec5 mm, procfs: breakdown RSS for anon, shmem and file in /proc/pid/status
There are several shortcomings with the accounting of shared memory
(SysV shm, shared anonymous mapping, mapping of a tmpfs file).  The
values in /proc/<pid>/status and <...>/statm don't allow to distinguish
between shmem memory and a shared mapping to a regular file, even though
theirs implication on memory usage are quite different: during reclaim,
file mapping can be dropped or written back on disk, while shmem needs a
place in swap.

Also, to distinguish the memory occupied by anonymous and file mappings,
one has to read the /proc/pid/statm file, which has a field for the file
mappings (again, including shmem) and total memory occupied by these
mappings (i.e.  equivalent to VmRSS in the <...>/status file.  Getting
the value for anonymous mappings only is thus not exactly user-friendly
(the statm file is intended to be rather efficiently machine-readable).

To address both of these shortcomings, this patch adds a breakdown of
VmRSS in /proc/<pid>/status via new fields RssAnon, RssFile and
RssShmem, making use of the previous preparatory patch.  These fields
tell the user the memory occupied by private anonymous pages, mapped
regular files and shmem, respectively.  Other existing fields in /status
and /statm files are left without change.  The /statm file can be
extended in the future, if there's a need for that.

Example (part of) /proc/pid/status output including the new Rss* fields:

VmPeak:  2001008 kB
VmSize:  2001004 kB
VmLck:         0 kB
VmPin:         0 kB
VmHWM:      5108 kB
VmRSS:      5108 kB

Vlastimil Babka c261e7d94f mm, proc: account for shmem swap in /proc/pid/smaps
Currently, /proc/pid/smaps will always show "Swap: 0 kB" for
shmem-backed mappings, even if the mapped portion does contain pages
that were swapped out.  This is because unlike private anonymous
mappings, shmem does not change pte to swap entry, but pte_none when
swapping the page out.  In the smaps page walk, such page thus looks
like it was never faulted in.

This patch changes smaps_pte_entry() to determine the swap status for
such pte_none entries for shmem mappings, similarly to how
mincore_page() does it.  Swapped out shmem pages are thus accounted for.
For private mappings of tmpfs files that COWed some of the pages, swaped
out status of the original shmem pages is naturally ignored.  If some of
the private copies was also swapped out, they are accounted via their
page table swap entries, so the resulting reported swap usage is then a
sum of both swapped out private copies, and swapped out shmem pages that
were not COWed.  No double accounting can thus happen.

The accounting is arguably still not as precise as for private anonymous
mappings, since now we will count also pages that the process in
question never accessed, but another process populated them and then let
them become swapped out.  I believe it is still less confusing and
subtle than not showing any swap usage by shmem mappings at all.
Swapped out counter might of interest of users who would like to prevent
from future swapins during performance critical operation and pre-fault
them at their convenience.  Especially for larger swapped out regions
the cost of swapin is much higher than a fresh page allocation.  So a
differentiation between pte_none vs.  swapped out is important for those
usecases.

One downside of this patch is that it makes /proc/pid/smaps more
expensive for shmem mappings, as we consult the radix tree for each
pte_none entry, so the overal complexity is O(n*log(n)).  I have
measured this on a process that creates a 2GB mapping and dirties single
pages with a stride of 2MB, and time how long does it take to cat
/proc/pid/smaps of this process 100 times.

Private anonymous mapping:

real    0m0.949s
user    0m0.116s
sys     0m0.348s

Mapping of a /dev/shm/file:

real    0m3.831s
user    0m0.180s
sys     0m3.212s

The difference is rather substantial, so the next patch will reduce the
cost for shared or read-only mappings.

In a less controlled experiment, I've gathered pids of processes on my
desktop that have either '/dev/shm/*' or 'SYSV*' in smaps.  This
included the Chrome browser and some KDE processes.  Again, I've run cat
/proc/pid/smaps on each 100 times.

Before this patch:

real    0m9.050s
user    0m0.518s
sys     0m8.066s

After this patch:

real    0m9.221s
user    0m0.541s
sys     0m8.187s

This suggests low impact on average systems.

Note that this patch doesn't attempt to adjust the SwapPss field for
shmem mappings, which would need extra work to determine who else could
have the pages mapped.  Thus the value stays zero except for COWed
swapped out pages in a shmem mapping, which are accounted as usual.

Vlastimil Babka bf9683d699 mm, documentation: clarify /proc/pid/status VmSwap limitations for shmem
This series is based on Jerome Marchand's [1] so let me quote the first
paragraph from there:

There are several shortcomings with the accounting of shared memory
(sysV shm, shared anonymous mapping, mapping to a tmpfs file).  The
values in /proc/<pid>/status and statm don't allow to distinguish
between shmem memory and a shared mapping to a regular file, even though
their implications on memory usage are quite different: at reclaim, file
mapping can be dropped or written back on disk while shmem needs a place
in swap.  As for shmem pages that are swapped-out or in swap cache, they
aren't accounted at all.

The original motivation for myself is that a customer found (IMHO
rightfully) confusing that e.g.  top output for process swap usage is
unreliable with respect to swapped out shmem pages, which are not
accounted for.

The fundamental difference between private anonymous and shmem pages is
that the latter has PTE's converted to pte_none, and not swapents.  As
such, they are not accounted to the number of swapents visible e.g.  in
/proc/pid/status VmSwap row.  It might be theoretically possible to use
swapents when swapping out shmem (without extra cost, as one has to
change all mappers anyway), and on swap in only convert the swapent for
the faulting process, leaving swapents in other processes until they
also fault (so again no extra cost).  But I don't know how many
assumptions this would break, and it would be too disruptive change for
a relatively small benefit.

Instead, my approach is to document the limitation of VmSwap, and
provide means to determine the swap usage for shmem areas for those who
are interested and willing to pay the price, using /proc/pid/smaps.
Because outside of ipcs, I don't think it's possible to currently to
determine the usage at all.  The previous patchset [1] did introduce new
shmem-specific fields into smaps output, and functions to determine the
values.  I take a simpler approach, noting that smaps output already has
a "Swap: X kB" line, where currently X == 0 always for shmem areas.  I
think we can just consider this a bug and provide the proper value by
consulting the radix tree, as e.g.  mincore_page() does.  In the patch
changelog I explain why this is also not perfect (and cannot be without
swapents), but still arguably much better than showing a 0.

The last two patches are adapted from Jerome's patchset and provide a
VmRSS breakdown to RssAnon, RssFile and RssShm in /proc/pid/status.
Hugh noted that this is a welcome addition, and I agree that it might
help e.g.  debugging process memory usage at albeit non-zero, but still
rather low cost of extra per-mm counter and some page flag checks.

[1] http://lwn.net/Articles/611966/

This patch (of 6):

The documentation for /proc/pid/status does not mention that the value
of VmSwap counts only swapped out anonymous private pages, and not
swapped out pages of the underlying shmem objects (for shmem mappings).
This is not obvious, so document this limitation.

to make sure that page_symlink/__page_symlink won't do the same

Bindings for Samsung S2M and S5M family PMICs are in mess. They are

This pull includes driver updates from the usual suspects (bfa, arcmsr,
 scsi_dh_alua, lpfc, storvsc, cxlflash).  The major change is the addition of
 the hisi_sas driver, which is an ARM platform device for SAS.  The other
 change of note is an enormous style transformation to the atp870u driver

Merge tag 'media/v4.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull second batch of media updates from Mauro Carvalho Chehab:
 "This is the second part of the media patches.  It contains the media
  controller next generation patches, with is the result of one year of
  discussions and development.  It also contains patches to enable media
  controller support at the DVB subsystem.

  The goal is to improve the media controller to allow proper support
  for other types of Video4Linux devices (radio and TV ones) and to
  extend the media controller functionality to allow it to be used by
  other subsystems like DVB, ALSA and IIO.

  In order to use the new functionality, a new ioctl is needed
  (MEDIA_IOC_G_TOPOLOGY).  As we're still discussing how to pack the
  struct fields of this ioctl in order to avoid compat32 issues, I
  decided to add a patch at the end of this series commenting out the
  new ioctl, in order to postpone the addition of the new ioctl to the
  next Kernel version (4.6).

  With that, no userspace visible changes should happen at the media
  controller API, as the existing ioctls are untouched.  Yet, it helps
  DVB, ALSA and IIO developers to develop and test the patches adding
  media controller support there, as the core will contain all required
  internal changes to allow adding support for devices that belong to
  those subsystems"

Linus Torvalds ac53b2e053 MTD updates for v4.5:
Generic MTD
 
  * populate the MTD device 'of_node' field (and get a proper 'of_node' symlink
    in sysfs)
    - This yielded some new helper functions, and changes across a variety of
      drivers
 
  * partitioning cleanups, to prepare for better device-tree based partitioning
    in the future
    - Eliminate a lot of boilerplate for drivers that want to use OF-based
      partition parsing
    - The DT bindings for this didn't settle yet, so most non-cleanup portions
      are deferred for a future release
 
 NAND
 
  * embed a struct mtd_info inside struct nand_chip
    - This is really long overdue; too many drivers have to do the same silly
      boilerplate to allocate and link up two "independent" structs, when in
      fact, everyone is assuming there is an exact 1:1 relationship between a
      NAND chips struct and its underlying MTD. This aids improved helpers and
      should make certain abstractions easier in the future.
    - Also causes a lot of churn, helped along by some automated code
      transformations
 
  * add more core support for detecting (and "correcting") bitflips in erased
    pages; requires opt-in by drivers, but at least we kill a few bad
    implementations and hopefully stave off future ones
 
  * pxa3xx_nand: cleanups, a few fixes, and PM improvements
 
  * new JZ4780 NAND driver
 
 SPI NOR
 
  * provide default erase function, for controllers that just want to send the
    SECTOR_ERASE command directly
 
  * fix some module auto-loading issues with device tree ("jedec,spi-nor")
 
  * error handling fixes
 
  * new Mediatek QSPI flash driver
 
 Other
 
  * cfi: force valid geometry Kconfig (finally!)
    - this one used to trip up randconfigs occasionally, since bots aren't
      deterred by big scary "advanced configuration" menus
 
 More? Probably. See the commit logs.

Linus Torvalds 67990608c8 Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's
    AML debugger introduced in the previous cycle and a new user
    space tool for that, fix some bugs related to the AML debugger
    and clean up the code in question (Lv Zheng, Dan Carpenter,
    Colin Ian King, Markus Elfring).
 
  - Update ACPICA to upstream revision 20151218 including a number
    of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng,
    Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box,
    Rafael Wysocki).
 
    In particular, the previously added erroneous support for the
    _SUB object is dropped, the concatenate operator will support
    all ACPI objects now, the Debug Object handling is improved,
    the SuperName handling of parameters being control methods is
    fixed, the ObjectType operator handling is updated to follow
    ACPI 5.0A and the handling of CondRefOf and RefOf is updated
    accordingly, module-level code will be executed after loading
    each ACPI table now (instead of being run once after all tables
    containing AML have been loaded), the Operation Region handlers
    management is updated to fix some reported problems and a the
    ACPICA code in the kernel is more in line with the upstream
    now.
 
  - Update the ACPI backlight driver to provide information on
    whether or not it will generate key-presses for brightness

Merge tag 'pm+acpi-4.5-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull oower management and ACPI updates from Rafael Wysocki:
 "As far as the number of commits goes, ACPICA takes the lead this time,
  followed by cpufreq and the device properties framework changes.

  The most significant new feature is the debugfs-based interface to the
  ACPICA's AML debugger added in the previous cycle and a new user space
  tool for accessing it.

  On the cpufreq front, the core is updated to handle governors more
  efficiently, particularly on systems where a single cpufreq policy
  object is shared between multiple CPUs, and there are quite a few
  changes in drivers (intel_pstate, cpufreq-dt etc).

  The device properties framework is updated to handle built-in (ie
  included in the kernel itself) device properties better, among other
  things by adding a fallback mechanism that will allow drivers to
  provide default properties to be used in case the plaform firmware
  doesn't provide the properties expected by them.

  The Operating Performance Points (OPP) framework gets new DT bindings
  and debugfs support.

  A new cpufreq driver for ST platforms is added and the ACPI driver for
  AMD SoCs will now support the APM X-Gene ACPI I2C device.

  The rest is mostly fixes and cleanups all over.

  Specifics:

   - Add a debugfs-based interface for interacting with the ACPICA's AML
     debugger introduced in the previous cycle and a new user space tool
     for that, fix some bugs related to the AML debugger and clean up
     the code in question (Lv Zheng, Dan Carpenter, Colin Ian King,
     Markus Elfring).

   - Update ACPICA to upstream revision 20151218 including a number of
     fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe
     Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael
     Wysocki).

     In particular, the previously added erroneous support for the _SUB
     object is dropped, the concatenate operator will support all ACPI
     objects now, the Debug Object handling is improved, the SuperName
     handling of parameters being control methods is fixed, the
     ObjectType operator handling is updated to follow ACPI 5.0A and the
     handling of CondRefOf and RefOf is updated accordingly, module-
     level code will be executed after loading each ACPI table now
     (instead of being run once after all tables containing AML have
     been loaded), the Operation Region handlers management is updated
     to fix some reported problems and a the ACPICA code in the kernel
     is more in line with the upstream now.

   - Update the ACPI backlight driver to provide information on whether
     or not it will generate key-presses for brightness change hotkeys
     and update some platform drivers (dell-wmi, thinkpad_acpi) to use
     that information to avoid sending double key-events to users pace
     for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu,
     Adrien Schildknecht).

   - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).

   - Fix the handling of the list of device IDs of device objects found
     in the ACPI namespace and add a helper for checking if there is a
     device object for a given device ID (Lukas Wunner).

     struct acpi_device objects for all ACPI device objects found in the
     namespace even if _STA fails for them which helps to avoid device
     enumeration problems on Microsoft Surface 3 (Aaron Lu).

     for AMD SoCs (Loc Ho).

     where ACPI tables have no power management support for the DMA

Linus Torvalds 34a9304a96 Merge branch 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:

 - cgroup v2 interface is now official.  It's no longer hidden behind a
   devel flag and can be mounted using the new cgroup2 fs type.

   Unfortunately, cpu v2 interface hasn't made it yet due to the
   discussion around in-process hierarchical resource distribution and
   only memory and io controllers can be used on the v2 interface at the
   moment.

 - The existing documentation which has always been a bit of mess is
   relocated under Documentation/cgroup-v1/. Documentation/cgroup-v2.txt
   is added as the authoritative documentation for the v2 interface.

 - Some features are added through for-4.5-ancestor-test branch to
   enable netfilter xt_cgroup match to use cgroup v2 paths.  The actual
   netfilter changes will be merged through the net tree which pulled in
   the said branch.

 - Various cleanups

Pull misc vfs updates from Al Viro:
 "All kinds of stuff.  That probably should've been 5 or 6 separate
  branches, but by the time I'd realized how large and mixed that bag
  had become it had been too close to -final to play with rebasing.

  Some fs/namei.c cleanups there, memdup_user_nul() introduction and
  switching open-coded instances, burying long-dead code, whack-a-mole
  of various kinds, several new helpers for ->llseek(), assorted
  cleanups and fixes from various people, etc.

  One piece probably deserves special mention - Neil's
  lookup_one_len_unlocked().  Similar to lookup_one_len(), but gets
  called without ->i_mutex and tries to avoid ever taking it.  That, of
  course, means that it's not useful for any directory modifications,
  but things like getting inode attributes in nfds readdirplus are fine
  with that.  I really should've asked for moratorium on lookup-related
  changes this cycle, but since I hadn't done that early enough...  I
  *am* asking for that for the coming cycle, though - I'm going to try
  and get conversion of i_mutex to rwsem with ->lookup() done under lock
  taken shared.

  There will be a patch closer to the end of the window, along the lines
  of the one Linus had posted last May - mechanical conversion of
  ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
  inode_is_locked()/inode_lock_nested().  To quote Linus back then:
