  KVM: page_track: fix access to NULL slot (2016-03-22 17:27:28 +0100)

----------------------------------------------------------------
* Build fixes for PPC KVM
* Miscellaneous bugfixes for ARM KVM
* Cleanup of memory barrier and removal of redundant barriers
* x86 fixes: page tracking oops, support for old buggy KVM nested on 4.5
* Support for protection keys in guests
* Lockdep fix
* Another conversion to simple wait queues and raw spinlocks,
  backported from PREEMPT_RT
