Memcg aligns memory.limit_in_bytes to PAGE_SIZE as part of the resource
counter since it makes no sense to allow a partial page to be charged.

As a result of the hugetlb cgroup using the resource counter, it is also
aligned to PAGE_SIZE but makes no sense unless aligned to the size of
the hugepage being limited.

Align hugetlb cgroup limit to hugepage size.

Revert "proc: Point /proc/{mounts,net} at /proc/thread-self/{mounts,net} instead of /proc/self/{mounts,net}"

This reverts commits 344470ca and e8132440.

It turns out that the exact path in the symlink matters, if for somewhat
unfortunate reasons: some apparmor configurations don't allow dhclient
access to the per-thread /proc files.  As reported by Jörg Otte:

  audit: type=1400 audit(1407684227.003:28): apparmor="DENIED"
    operation="open" profile="/sbin/dhclient"
    name="/proc/1540/task/1540/net/dev" pid=1540 comm="dhclient"
    requested_mask="r" denied_mask="r" fsuid=0 ouid=0

so we had better revert this for now.  We might be able to work around
this in practice by only using the per-thread symlinks if the thread
isn't the thread group leader, and if the namespaces differ between
threads (which basically never happens).

We'll see. In the meantime, the revert was made to be intentionally easy.

 "Apologies for not getting this done in time for Dave's drm-next merge

  to track it down.  In any case, Dave suggested I try my luck by
  sending directly to you this time.

  Overview:

   - more code for Tegra GK20A from NVIDIA - probing, reclockig
   - better fix for Kepler GPUs that have the graphics engine powered
     off on startup, method courtesy of info provided by NVIDIA
   - unhardcoding of a bunch of graphics engine setup on
     Fermi/Kepler/Maxwell, will hopefully solve some issues people have
     noticed on higher-end models
   - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs
     userspace support in general, but some lucky apps will benefit
     automagically
   - reviewed/exposed the full object APIs to userspace (finally), gives
     it access to perfctrs, ZBC controls, various events.  More to come

Pull trace file read iterator fixes from Steven Rostedt:
 "This contains a fix for two long standing bugs.  Both of which are
  rarely ever hit, and requires the user to do something that users
  rarely do.  It took a few special test cases to even trigger this bug,
  and one of them was just one test in the process of finishing up as
  another one started.

  Both bugs have to do with the ring buffer iterator rb_iter_peek(), but
  one is more indirect than the other.

  The fist bug fix is simply an increase in the safety net loop counter.
  The counter makes sure that the rb_iter_peek() only iterates the
  number of times we expect it can, and no more.  Well, there was one
  way it could iterate one more than we expected, and that caused the
  ring buffer to shutdown with a nasty warning.  The fix was simply to
  up that counter by one.

  The other bug has to be with rb_iter_reset() (called by
  rb_iter_peek()).  This happens when a user reads both the trace_pipe
  and trace files.  The trace_pipe is a consuming read and does not use
  the ring buffer iterator, but the trace file is not a consuming read
  and does use the ring buffer iterator.  When the trace file is being
  read, if it detects that a consuming read occurred, it resets the
  iterator and starts over.  But the reset code that does this
  (rb_iter_reset()), checks if the reader_page is linked to the ring
  buffer or not, and will look into the ring buffer itself if it is not.
  This is wrong, as it should always try to read the reader page first.
  Not to mention, the code that looked into the ring buffer did it
  wrong, and used the header_page "read" offset to start reading on that
  page.  That offset is bogus for pages in the writable ring buffer, and
  was corrupting the iterator, and it would start returning bogus
  events"

  ring-buffer: Always reset iterator to reader page

Pull namespace updates from Eric Biederman:
 "This is a bunch of small changes built against 3.16-rc6.  The most
  significant change for users is the first patch which makes setns
  drmatically faster by removing unneded rcu handling.

  The next chunk of changes are so that "mount -o remount,.." will not
  allow the user namespace root to drop flags on a mount set by the
  system wide root.  Aks this forces read-only mounts to stay read-only,
  no-dev mounts to stay no-dev, no-suid mounts to stay no-suid, no-exec
  mounts to stay no exec and it prevents unprivileged users from messing
  with a mounts atime settings.  I have included my test case as the
  last patch in this series so people performing backports can verify
  this change works correctly.

  The next change fixes a bug in NFS that was discovered while auditing
  nsproxy users for the first optimization.  Today you can oops the
  kernel by reading /proc/fs/nfsfs/{servers,volumes} if you are clever
  with pid namespaces.  I rebased and fixed the build of the
  !CONFIG_NFS_FS case yesterday when a build bot caught my typo.  Given
  that no one to my knowledge bases anything on my tree fixing the typo
  in place seems more responsible that requiring a typo-fix to be
  backported as well.

  The last change is a small semantic cleanup introducing
  /proc/thread-self and pointing /proc/mounts and /proc/net at it.  This
  prevents several kinds of problemantic corner cases.  It is a
  user-visible change so it has a minute chance of causing regressions
  so the change to /proc/mounts and /proc/net are individual one line
  commits that can be trivially reverted.  Unfortunately I lost and
  could not find the email of the original reporter so he is not
  credited.  From at least one perspective this change to /proc/net is a
  refgression fix to allow pthread /proc/net uses that were broken by
  the introduction of the network namespace"

  to go upstream at this point in time, but DaveM would rather see them
  upstream now so who am I to argue.  As the patches are both very
