  Merge tag 'kvm-arm-for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2016-12-12 07:29:39 +0100)

----------------------------------------------------------------
Small release, the most interesting stuff is x86 nested virt improvements.

x86: userspace can now hide nested VMX features from guests; nested
VMX can now run Hyper-V in a guest; support for AVX512_4VNNIW and
AVX512_FMAPS in KVM; infrastructure support for virtual Intel GPUs.

PPC: support for KVM guests on POWER9; improved support for interrupt
polling; optimizations and cleanups.

s390: two small optimizations, more stuff is in flight and will be
in 4.11.

ARM: support for the GICv3 ITS on 32bit platforms.
