Pull more KVM updates from Paolo Bonzini:
"Second round of KVM changes for 4.6:
- 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"
