Although mem_cgroup_uncharge_swap has an empty placeholder for
!CONFIG_CGROUP_MEM_RES_CTLR_SWAP the definition is placed in the
CONFIG_SWAP ifdef block so we are missing the same definition for
!CONFIG_SWAP which implies !CONFIG_CGROUP_MEM_RES_CTLR_SWAP.

This has not been an issue before, because mem_cgroup_uncharge_swap was
not called from !CONFIG_SWAP context.  But Hugh Dickins has a cleanup
patch to call __mem_cgroup_commit_charge_swapin which is defined also
for !CONFIG_SWAP.

Let's move both the empty definition and declaration outside of the
CONFIG_SWAP block to avoid the following compilation error:

  mm/memcontrol.c: In function '__mem_cgroup_commit_charge_swapin':
  mm/memcontrol.c:2837: error: implicit declaration of function 'mem_cgroup_uncharge_swap'

if CONFIG_SWAP is disabled.

As described in e6fa16ab ("signal: sigprocmask() should do

Also, use the new helper function introduced in commit 5e6292c0

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

It was introduced by d1d5e05f ("hugetlbfs: return error code when
initializing module") but as Al pointed out, is a bad idea.

Quoted comments from Al:
 "Note that unregister_filesystem() in module init is *always* wrong;
  it's not an issue here (it's done too early to care about and
  realistically the box is not going anywhere - it'll panic when attempt
  to exec /sbin/init fails, if not earlier), but it's a damn bad
  example.

  Consider a normal fs module.  Somebody loads it and in parallel with
  that we get a mount attempt on that fs type.  It comes between
  register and failure exits that causes unregister; at that point we
  are screwed since grabbing a reference to module as done by mount is
  enough to prevent exit, but not to prevent the failure of init.  As
  the result, module will get freed when init fails, mounted fs of that
  type be damned."

So remove it.

Change send_sig_all() to use do_send_sig_info(SEND_SIG_FORCED) instead
of force_sig(SIGKILL).  With the recent changes we do not need force_ to
kill the CLONE_NEWPID tasks.

And this is more correct.  force_sig() can race with the exiting thread,
while do_send_sig_info(group => true) kill the whole process.

Some more notes from Oleg Nesterov:

> Just one note. This change makes no difference for sysrq_handle_kill().
> But it obviously changes the behaviour sysrq_handle_term(). I think
> this is fine, if you want to really kill the task which blocks/ignores
> SIGTERM you can use sysrq_handle_kill().
>
> Even ignoring the reasons why force_sig() is simply wrong here,
> force_sig(SIGTERM) looks strange. The task won't be killed if it has
> a handler, but SIG_IGN can't help. However if it has the handler
> but blocks SIGTERM temporary (this is very common) it will be killed.

Also,

> force_sig() can't kill the process if the main thread has already
> exited. IOW, it is trivial to create the process which can't be
> killed by sysrq.

So, this patch fixes the issue.

The proc_parse_options() call from proc_mount() runs only once at boot
time.  So on any later mount attempt, any mount options are ignored
because ->s_root is already initialized.

As a consequence, "mount -o <options>" will ignore the options.  The
only way to change mount options is "mount -o remount,<options>".

To fix this, parse the mount options unconditionally.

Pull DMA mapping branch from Marek Szyprowski:
 "Short summary for the whole series:

  A few limitations have been identified in the current dma-mapping
  design and its implementations for various architectures.  There exist
  more than one function for allocating and freeing the buffers:
  currently these 3 are used dma_{alloc, free}_coherent,
  dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.

  For most of the systems these calls are almost equivalent and can be
  interchanged.  For others, especially the truly non-coherent ones
  (like ARM), the difference can be easily noticed in overall driver
  performance.  Sadly not all architectures provide implementations for
  all of them, so the drivers might need to be adapted and cannot be
  easily shared between different architectures.  The provided patches
  unify all these functions and hide the differences under the already
  existing dma attributes concept.  The thread with more references is
  available here:

    http://www.spinics.net/lists/linux-sh/msg09777.html

  These patches are also a prerequisite for unifying DMA-mapping
  implementation on ARM architecture with the common one provided by
  dma_map_ops structure and extending it with IOMMU support.  More
  information is available in the following thread:

    http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819

  More works on dma-mapping framework are planned, especially in the
  area of buffer sharing and managing the shared mappings (together with
  the recently introduced dma_buf interface: commit d15bd7ee
  "dma-buf: Introduce dma buffer sharing mechanism").

  The patches in the current set introduce a new alloc/free methods
  (with support for memory attributes) in dma_map_ops structure, which
  will later replace dma_alloc_coherent and dma_alloc_writecombine
  functions."

People finally started piping up with support for merging this, so I'm
merging it as the last of the pending stuff from the merge window.
Looks like pohmelfs is going to wait for 3.5 and more external support
for merging.

Merge common_audit_data cleanup patches from Eric Paris.

This is really too late, but it's a long-overdue cleanup of the costly
wrapper functions for the security layer.

The "struct common_audit_data" is used all over in critical paths,
allocated and initialized on the stack.  And used to be much too large,
causing not only unnecessarily big stack frames but the clearing of the
(mostly useless) data was also very visible in profiles.

As a particular example, in one microbenchmark for just doing "stat()"
over files a lot, selinux_inode_permission() used 7% of the CPU time.
That's despite the fact that it doesn't actually *do* anything: it is
just a helper wrapper function in the selinux security layer.

This patch-series shrinks "struct common_audit_data" sufficiently that
code generation for these kinds of wrapper functions is improved
noticeably, and we spend much less time just initializing data that we
will never use.

The functions still get called all the time, and it still shows up at
3.5+% in my microbenchmark, but it's quite a bit lower down the list,
and much less noticeable.

Pull ARM fixes from Russell King:
 "Nothing too big here, just small fixes."

* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
  ARM: fix more fallout from 9f97da78 (Disintegrate asm/system.h for ARM)
  ARM: fix bios32.c build warning
  ARM: 7337/1: ptrace: fix ptrace_read_user for !CONFIG_MMU platforms
  ARM: fix missing bug.h include in arch/arm/kernel/insn.c
  ARM: sa11x0: fix build errors from DMA engine API updates

Pull Sparc fixes from David Miller:
 "One build regression and one serial probe regression fix on sparc."

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  serial/sunzilog: fix keyboard on SUN SPARCstation
  sparc: pgtable_64: change include order

To fix:

  In file included from kernel/exit.c:61:
  arch/avr32/include/asm/mmu_context.h: In function 'enable_mmu':
  arch/avr32/include/asm/mmu_context.h:135: error: implicit declaration of function 'nop'

It needs an include of the new file created in commit ae473946
("Disintegrate asm/system.h for AVR32"), but since that file only
contains "nop", and since other arch already have precedent of putting
nop in asm/barrier.h we should just delete the new file and put nop in
barrier.h

This reverts commit d06221c0.

It turns out to trigger the "BUG_ON(!PageCompound(page))" in kfree(),
apparently because the code ends up trying to free somethng that was
never kmalloced in the first place.

BenH points out that the patch was untested and wasn't meant to go into
the upstream kernel that quickly in the first place.

MCA details seldom change inbetween the models of a family so don't
be too conservative and enable decoding on everything starting from
K8 onwards. Minor adjustments can come in later but most importantly,
we have some decoding infrastructure in place for upcoming models by
default.

The keyboard on my SUN SPARCstation 5 no longer worked.

    The culprint was: d4e33fac
    ("serial: Kill off NO_IRQ")

Fix up logic for no irq / irq so the keyboard works again.
