Pull powerpc EEH bugfixes from Benjamin Herrenschmidt.

Two one-liner fixes for the new EEH code.

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/eeh: Do not invalidate PE properly
  powerpc/pseries: Fix oops with MSIs when missing EEH PEs

Pull MIPS fixes from Ralf Baechle:
 "Three issues fixed accross the field:

   - Some functions that were recently outlined as part of a preemption
     fix were causing problems with function tracing.
   - The recently merged in-kernel MPI library uses very outdated
     headers that contain MIPS-specific code which won't build on with
     gcc 4.4 or newer.
   - The MIPS non-NUMA memory initialization was making only a very
     half-baked attempt at merging adjacent memory ranges.  This kept
     the code simple enough but is now causing issues with kexec."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MPI: Fix compilation on MIPS with GCC 4.4 and newer
  MIPS: Fix crash that occurs when function tracing is enabled
  MIPS: Merge overlapping bootmem ranges

While the EEH does recovery on the specific PE that has PCI errors,
the PCI devices belonging to the PE will be removed and the PE will
be marked as invalid since we still need the information stored in
the PE. We only invalidate the PE when it doesn't have associated
EEH devices and valid child PEs. However, the code used to check
that is wrong. The patch fixes that.

Pull MTD fixes from David Woodhouse:
 "The most important part of this is that it fixes a regression in
  Samsung NAND chip detection, introduced by some rework which went into
  3.7.  The initial fix wasn't quite complete, so it's in two parts.  In
  fact the first part is committed twice (Artem committed his own copy
  of the same patch) and I've merged Artem's tree into mine which
  already had that fix.

  I'd have recommitted that to make it somewhat cleaner, but figured by
  this point in the release cycle it was better to merge *exactly* the
  commits which have been in linux-next.

  If I'd recommitted, I'd also omit the sparse warning fix.  But it's
  there, and it's harmless — just marking one function as 'static' in
  onenand code.

  This also includes a couple more fixes for stable: an AB-BA deadlock
  in JFFS2, and an invalid range check in slram."
