c06bb5d49d [PATCH] Fix VIA quirks
Fix VIA quirks that were recently broken by Alan Cox in the upstream
kernel (commit 1597cacbe3).

My understanding is that pci_find_present() doesn't work yet at the time
the quirks are run.  So I used a two-step quirk as is done for some other
quirks already.  First we detect the VIA south bridges and set the right
low and high device limits, then we are ready to actually run the quirks on
the affected devices.

The message can be generated in a quite normal situation:
 If a 'lock' request is interrupted, then the lock client needs to
  record that the server has the lock, incase it does.
 When we come the unlock, the server might say it doesn't, even
  though we think it does (or might) and this generates the message.

When expanding the stack, we don't currently check if the VMA will cross
into an area of the address space that is reserved for hugetlb pages.
Subsequent faults on the expanded portion of such a VMA will confuse the
low-level MMU code, resulting in an OOPS.  Check for this.

bcdddfb66c Revert "net: ifb error path loop fix"
This reverts commit 0c0b3ae68e.

Quoth David:

  "Jeff, please revert

   It's wrong.  We had a lengthy analysis of this piece of code
   several months ago, and it is correct.

   Consider, if we run the loop and we get an error
   the following happens:

   1) attempt of ifb_init_one(i) fails, therefore we should
      not try to "ifb_free_one()" on "i" since it failed
   2) the loop iteration first increments "i", then it
      check for error

   Therefore we must decrement "i" twice before the first
   free during the cleanup.  One to "undo" the for() loop
   increment, and one to "skip" the ifb_init_one() case which
   failed."

0f2452855d [PATCH] namespaces: fix task exit disaster
This is based on a patch by Eric W.  Biederman, who pointed out that pid
namespaces are still fake, and we only have one ever active.

So for the time being, we can modify any code which could access
tsk->nsproxy->pid_ns during task exit to just use &init_pid_ns instead,
and move the exit_task_namespaces call in do_exit() back above
exit_notify(), so that an exiting nfs server has a valid tsk->sighand to
work with.

Long term, pulling pid_ns out of nsproxy might be the cleanest solution.

701dfbc1cb [PATCH] mm: mremap correct rmap accounting
Nick Piggin points out that page accounting on MIPS multiple ZERO_PAGEs
is not maintained by its move_pte, and could lead to freeing a ZERO_PAGE.

Instead of complicating that move_pte, just forget the minor optimization
when mremapping, and change the one thing which needed it for correctness
- filemap_xip use ZERO_PAGE(0) throughout instead of according to address.

[ "There is no block device driver one could use for XIP on mips
   platforms" - Carsten Otte ]
