Pull Xen bugfixes from David Vrabel:
 "Fix two bugs that cause x86 PV guest crashes.

  1. Ballooning a 32-bit guest would eventually crash it.

  2. Revert a broken fix for a regression with NUMA_BALACING.  The bad
     fix caused PV guests to crash after migration.  This is not ideal
     but unpicking the madness that is _PAGE_NUMA == _PAGE_PROTNONE will
     take a while longer"

* tag 'stable/for-linus-3.14-rc8-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
  Revert "xen: properly account for _PAGE_NUMA during xen pte translations"
  xen/balloon: flush persistent kmaps in correct position
