KAMEZAWA Hiroyuki 4b91355e9d memcg: fix/change behavior of shared anon at moving task
This patch changes memcg's behavior at task_move().

At task_move(), the kernel scans a task's page table and move the changes
for mapped pages from source cgroup to target cgroup.  There has been a
bug at handling shared anonymous pages for a long time.

Before patch:
  - The spec says 'shared anonymous pages are not moved.'
  - The implementation was 'shared anonymoys pages may be moved'.
    If page_mapcount <=2, shared anonymous pages's charge were moved.

After patch:
  - The spec says 'all anonymous pages are moved'.
  - The implementation is 'all anonymous pages are moved'.

Considering usage of memcg, this will not affect user's experience.
'shared anonymous' pages only exists between a tree of processes which
don't do exec().  Moving one of process without exec() seems not sane.
For example, libcgroup will not be affected by this change.  (Anyway, no
one noticed the implementation for a long time...)

Below is a discussion log:

 - current spec/implementation are complex
 - Now, shared file caches are moved
 - It adds unclear check as page_mapcount(). To do correct check,
   we should check swap users, etc.
 - No one notice this implementation behavior. So, no one get benefit
   from the design.
 - In general, once task is moved to a cgroup for running, it will not
   be moved....
 - Finally, we have control knob as memory.move_charge_at_immigrate.

Here is a patch to allow moving shared pages, completely. This makes
memcg simpler and fix current broken code.

Hugh Dickins 17cf28afea mm/fs: remove truncate_range
Remove vmtruncate_range(), and remove the truncate_range method from
struct inode_operations: only tmpfs ever supported it, and tmpfs has now
converted over to using the fallocate method of file_operations.

Update Documentation accordingly, adding (setlease and) fallocate lines.
And while we're in mm.h, remove duplicate declarations of shmem_lock() and
shmem_file_setup(): everyone is now using the ones in shmem_fs.h.

Linus Torvalds ae32adc1e0 Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull i2c-embedded changes from Wolfram Sang:
 "Major changes:

   - lots of devicetree additions for existing drivers.  I tried hard to
     make sure the bindings are proper.  In more complicated cases, I
     requested acks from people having more experience with them than
     me.  That took a bit of extra time and also some time went into
     discussions with developers about what bindings are and what not.
     I have the feeling that the workflow with bindings should be
     improved to scale better.  I will spend some more thought on
     this...

   - i2c-muxes are succesfully used meanwhile, so we dropped
     EXPERIMENTAL for them and renamed the drivers to a standard pattern
     to match the rest of the subsystem.  They can also be used with
     devicetree now.

   - ixp2000 was removed since the whole platform goes away.

   - cleanups (strlcpy instead of strcpy, NULL instead of 0)

   - The rest is typical driver fixes I assume.

  All patches have been in linux-next at least since v3.4-rc6."

Fixed up trivial conflict in arch/arm/mach-lpc32xx/common.c due to the
same patch already having come in through the arm/soc trees, with
additional patches on top of it.

Linus Torvalds 2795343705 arm-soc: clock driver changes
The new clock subsystem was merged in linux-3.4 without any users, this
 now moves the first three platforms over to it: imx, mxs and spear.
 
 The series also contains the changes for the clock subsystem itself,
 since Mike preferred to have it together with the platforms that require
 these changes, in order to avoid interdependencies and conflicts.

Linus Torvalds d484864dd9 Merge branch 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull CMA and ARM DMA-mapping updates from Marek Szyprowski:
 "These patches contain two major updates for DMA mapping subsystem
  (mainly for ARM architecture).  First one is Contiguous Memory
  Allocator (CMA) which makes it possible for device drivers to allocate
  big contiguous chunks of memory after the system has booted.

  The main difference from the similar frameworks is the fact that CMA
  allows to transparently reuse the memory region reserved for the big
  chunk allocation as a system memory, so no memory is wasted when no
  big chunk is allocated.  Once the alloc request is issued, the
  framework migrates system pages to create space for the required big
  chunk of physically contiguous memory.

  For more information one can refer to nice LWN articles:

   - 'A reworked contiguous memory allocator':
		http://lwn.net/Articles/447405/

   - 'CMA and ARM':
		http://lwn.net/Articles/450286/

   - 'A deep dive into CMA':
		http://lwn.net/Articles/486301/

   - and the following thread with the patches and links to all previous
     versions:
		https://lkml.org/lkml/2012/4/3/204

  The main client for this new framework is ARM DMA-mapping subsystem.

  The second part provides a complete redesign in ARM DMA-mapping
  subsystem.  The core implementation has been changed to use common
  struct dma_map_ops based infrastructure with the recent updates for
  new dma attributes merged in v3.4-rc2.  This allows to use more than
  one implementation of dma-mapping calls and change/select them on the
  struct device basis.  The first client of this new infractructure is
  dmabounce implementation which has been completely cut out of the
  core, common code.

  The last patch of this redesign update introduces a new, experimental
  implementation of dma-mapping calls on top of generic IOMMU framework.
  This lets ARM sub-platform to transparently use IOMMU for DMA-mapping
  calls if one provides required IOMMU hardware.

  For more information please refer to the following thread:
		http://www.spinics.net/lists/arm-kernel/msg175729.html

  The last patch merges changes from both updates and provides a
  resolution for the conflicts which cannot be avoided when patches have
  been applied on the same files (mainly arch/arm/mm/dma-mapping.c)."

Daniel Vetter 4c78513e45 dma-buf: mmap support
Compared to Rob Clark's RFC I've ditched the prepare/finish hooks
and corresponding ioctls on the dma_buf file. The major reason for
that is that many people seem to be under the impression that this is
also for synchronization with outstanding asynchronous processsing.
I'm pretty massively opposed to this because:

- It boils down reinventing a new rather general-purpose userspace
  synchronization interface. If we look at things like futexes, this
  is hard to get right.
- Furthermore a lot of kernel code has to interact with this
  synchronization primitive. This smells a look like the dri1 hw_lock,
  a horror show I prefer not to reinvent.
- Even more fun is that multiple different subsystems would interact
  here, so we have plenty of opportunities to create funny deadlock
  scenarios.

I think synchronization is a wholesale different problem from data
sharing and should be tackled as an orthogonal problem.

Now we could demand that prepare/finish may only ensure cache
coherency (as Rob intended), but that runs up into the next problem:
We not only need mmap support to facilitate sw-only processing nodes
in a pipeline (without jumping through hoops by importing the dma_buf
into some sw-access only importer), which allows for a nicer
ION->dma-buf upgrade path for existing Android userspace. We also need
mmap support for existing importing subsystems to support existing
userspace libraries. And a loot of these subsystems are expected to
export coherent userspace mappings.

So prepare/finish can only ever be optional and the exporter /needs/
to support coherent mappings. Given that mmap access is always
somewhat fallback-y in nature I've decided to drop this optimization,
instead of just making it optional. If we demonstrate a clear need for
this, supported by benchmark results, we can always add it in again
later as an optional extension.

Other differences compared to Rob's RFC is the above mentioned support
for mapping a dma-buf through facilities provided by the importer.
Which results in mmap support no longer being optional.

Note that this dma-buf mmap patch does _not_ support every possible
insanity an existing subsystem could pull of with mmap: Because it
does not allow to intercept pagefaults and shoot down ptes importing
subsystems can't add some magic of their own at these points (e.g. to
automatically synchronize with outstanding rendering or set up some
special resources). I've done a cursory read through a few mmap
implementions of various subsytems and I'm hopeful that we can avoid
this (and the complexity it'd bring with it).

Additonally I've extended the documentation a bit to explain the hows
and whys of this mmap extension.

In case we ever want to add support for explicitly cache maneged
userspace mmap with a prepare/finish ioctl pair, we could specify that
userspace needs to mmap a different part of the dma_buf, e.g. the
range starting at dma_buf->size up to dma_buf->size*2. This works
because the size of a dma_buf is invariant over it's lifetime. The
exporter would obviously need to fall back to coherent mappings for
both ranges if a legacy clients maps the coherent range and the
architecture cannot suppor conflicting caching policies. Also, this
would obviously be optional and userspace needs to be able to fall
back to coherent mappings.

v2:
- Spelling fixes from Rob Clark.
- Compile fix for !DMA_BUF from Rob Clark.
- Extend commit message to explain how explicitly cache managed mmap
  support could be added later.
- Extend the documentation with implementations notes for exporters
  that need to manually fake coherency.

v3:
- dma_buf pointer initialization goof-up noticed by Rebecca Schultz
  Zavin.

Linus Torvalds b1bf7d4d1b GPIO driver changes for v3.5 merge window
Lots of gpio changes, both to core code and drivers.  Changes do touch
 architecture code to remove the need for separate arm/gpio.h includes
 in most architectures.  Some new drivers are added, and a number of
 gpio drivers are converted to use irq_domains for gpio inputs used as
 interrupts.  Device tree support has been amended to allow multiple
 gpio_chips to use the same device tree node.  Remaining changes are
 primarily bug fixes.

Pull main drm updates from Dave Airlie:
 "This is the main merge window request for the drm.

  It's big, but jam packed will lots of features and of course 0
  regressions.  (okay maybe there'll be one).

  Highlights:

   - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
     (qemu only).  These drivers use the generic modesetting drivers.

   - initial prime/dma-buf support for i915, nouveau, radeon, udl and
     exynos

   - switcheroo audio support: so GPUs with HDMI can turn off the sound
     driver without crashing stuff.

   - There are some patches drifting outside drivers/gpu into x86 and
     EFI for better handling of multiple video adapters in Apple Macs,
     they've got correct acks except one trivial fixup.

   - Core:
	edid parser has better DMT and reduced blanking support,
	crtc properties,
	plane properties,

   - Drivers:
	exynos: add 2D core accel support, prime support, hdmi features
	intel: more Haswell support, initial Valleyview support, more
	    hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
	    cleanups and fixes
	radeon: more HDMI audio support, improved GPU lockup recovery
	    support, remove nested mutexes, less memory copying on PCIE, fix
	    bus master enable race (kexec), improved fence handling
	gma500: cleanups, 1080p support, acpi fixes
	nouveau: better nva3 memory reclocking, kepler accel (needs
	    external firmware rip), async buffer moves on nv84+ hw.

  I've some more dma-buf patches that rely on the dma-buf merge for vmap
  stuff, and I've a few fixes building up, but I'd decided I'd better
  get rid of the main pull sooner rather than later, so the audio guys
  are also unblocked."

Pull user-space probe instrumentation from Ingo Molnar:
 "The uprobes code originates from SystemTap and has been used for years
  in Fedora and RHEL kernels.  This version is much rewritten, reviews
  from PeterZ, Oleg and myself shaped the end result.

  This tree includes uprobes support in 'perf probe' - but SystemTap
  (and other tools) can take advantage of user probe points as well.

  Sample usage of uprobes via perf, for example to profile malloc()
  calls without modifying user-space binaries.

  First boot a new kernel with CONFIG_UPROBE_EVENT=y enabled.

  If you don't know which function you want to probe you can pick one
  from 'perf top' or can get a list all functions that can be probed
  within libc (binaries can be specified as well):

	$ perf probe -F -x /lib/libc.so.6

  To probe libc's malloc():

	$ perf probe -x /lib64/libc.so.6 malloc
	Added new event:
	probe_libc:malloc    (on 0x7eac0)

  You can now use it in all perf tools, such as:

	perf record -e probe_libc:malloc -aR sleep 1

  Make use of it to create a call graph (as the flat profile is going to
  look very boring):

	$ perf record -e probe_libc:malloc -gR make

  The core uprobes design is fairly straightforward: uprobes probe
  points register themselves at (inode:offset) addresses of
  libraries/binaries, after which all existing (or new) vmas that map
  that address will have a software breakpoint injected at that address.
  vmas are COW-ed to preserve original content.  The probe points are
  kept in an rbtree.

  If user-space executes the probed inode:offset instruction address
  then an event is generated which can be recovered from the regular
  perf event channels and mmap-ed ring-buffer.

  Multiple probes at the same address are supported, they create a
  dynamic callback list of event consumers.

  The basic model is further complicated by the XOL speedup: the
  original instruction that is probed is copied (in an architecture
  specific fashion) and executed out of line when the probe triggers.
  The XOL area is a single vma per process, with a fixed number of
  entries (which limits probe execution parallelism).

  The API: uprobes are installed/removed via
  /sys/kernel/debug/tracing/uprobe_events, the API is integrated to
  align with the kprobes interface as much as possible, but is separate
  to it.

  Injecting a probe point is privileged operation, which can be relaxed
  by setting perf_paranoid to -1.

  You can use multiple probes as well and mix them with kprobes and
  regular PMU events or tracepoints, when instrumenting a task."

Fix up trivial conflicts in mm/memory.c due to previous cleanup of
unmap_single_vma().

Linus Torvalds d5b4bb4d10 Merge branch 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Pull the MCA deletion branch from Paul Gortmaker:
 "It was good that we could support MCA machines back in the day, but
  realistically, nobody is using them anymore.  They were mostly limited
  to 386-sx 16MHz CPU and some 486 class machines and never more than
  64MB of RAM.  Even the enthusiast hobbyist community seems to have
  dried up close to ten years ago, based on what you can find searching
  various websites dedicated to the relatively short lived hardware.

  So lets remove the support relating to CONFIG_MCA.  There is no point
  carrying this forward, wasting cycles doing routine maintenance on it;
  wasting allyesconfig build time on validating it, wasting I/O on git
  grep'ping over it, and so on."

Let's see if anybody screams.  It generally has compiled, and James
Bottomley pointed out that there was a MCA extension from NCR that
allowed for up to 4GB of memory and PPro-class machines.  So in *theory*
there may be users out there.

But even James (technically listed as a maintainer) doesn't actually
have a system, and while Alan Cox claims to have a machine in his cellar
that he offered to anybody who wants to take it off his hands, he didn't
argue for keeping MCA support either.

So we could bring it back.  But somebody had better speak up and talk
about how they have actually been using said MCA hardware with modern
kernels for us to do that.  And David already took the patch to delete
all the networking driver code (commit a5e371f61ad3: "drivers/net:
delete all code/drivers depending on CONFIG_MCA").

* 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:

  scsi: delete the MCA specific drivers and driver code

Linus Torvalds 2e341ca686 Sound updates for 3.5-rc1
This is the first big chunk for 3.5 merges of sound stuff.
 There are a few big changes in different areas.  First off, the
 streaming logic of USB-audio endpoints has been largely rewritten
 for the better support of "implicit feedback".  If anything about USB
 got broken, this change has to be checked.
 
 For HD-audio, the resume procedure was changed; instead of delaying
 the resume of the hardware until the first use, now waking up immediately
 at resume.  This is for buggy BIOS.
 
 For ASoC, dynamic PCM support and the improved support for digital links
 between off-SoC devices are major framework changes.
 
 Some highlights are below:
 
 * HD-audio
 - Avoid the accesses of invalid pin-control bits that may stall the codec
 - V-ref setup cleanups
 - Fix the races in power-saving code
 - Fix the races in codec cache hashes and connection lists
 - Split some common codes for BIOS auto-parser to hda_auto_parser.c
 - Changed the PM resume code to wake up immediately for buggy BIOS
 - Creative SoundCore3D support
 - Add Conexant CX20751/2/3/4 codec support
 
 * ASoC
 - Dynamic PCM support, allowing support for SoCs with internal routing
   through components with tight sequencing and formatting constraints
   within their internal paths or where there are multiple components
   connected with CPU managed DMA controllers inside the SoC.
 - Greatly improved support for direct digital links between off-SoC
   devices, providing a much simpler way of connecting things like digital
   basebands to CODECs.
 - Much more fine grained and robust locking, cleaning up some of the
   confusion that crept in with multi-component.
 - CPU support for nVidia Tegra 30 I2S and audio hub controllers and
   ST-Ericsson MSP I2S controolers
 - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas
   Instruments LM49453.
 - Some regmap changes needed by the Tegra I2S driver.
 - mc13783 audio support.
 
 * Misc
 - Rewrite with module_pci_driver()
 - Xonar DGX support for snd-oxygen
 - Improvement of packet handling in snd-firewire driver
 - New USB-endpoint streaming logic
 - Enhanced M-audio FTU quirks and relevant cleanups
 - Increment the support of OSS devices to 256
 - snd-aloop accuracy improvement
 
 There are a few more pending changes for 3.5, but they will be
 sent slightly later as partly depending on the changes of DRM.

Linus Torvalds 6f73b3629f Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Benjamin Herrenschmidt:
 "Here are the powerpc goodies for 3.5.  Main highlights are:

   - Support for the NX crypto engine in Power7+
   - A bunch of Anton goodness, including some micro optimization of our
     syscall entry on Power7
   - I converted a pile of our thermal control drivers to the new i2c
     APIs (essentially turning the old therm_pm72 into a proper set of
     windfarm drivers).  That's one more step toward removing the
     deprecated i2c APIs, there's still a few drivers to fix, but we are
     getting close
   - kexec/kdump support for 47x embedded cores

  The big missing thing here is no updates from Freescale.  Not sure
  what's up here, but with Kumar not working for them anymore things are
  a bit in a state of flux in that area."

Devendra Naga cad19fa664 Documentation/watchdog: Fix the file descriptor leak when no cmdline arg given
we start a infinite loop when user gives ./watchdog-test, and when user
ctrl + c's the program, we just exit immeadiately with out closing the
filedescriptor of the watchdog device. a signal handler is used to
do the job of closing the filedescriptor and exiting the program.
