Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git
tags/stable/for-linus-3.14-rc8-tag

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.

Thanks.

David
