[PULL 00/37] KVM/ARM Changes for v4.12 - Round 2

[Christoffer Dall]

Hi Paolo and Radim,

Here is a second round of KVM/ARM Changes for v4.12.  I only just put
these changes in kvmarm/next, but we've tested them pretty thoroughly.

I know it's late in the merge window, but if we can still get them into
v4.12 that would be good as the ITS save/restore impedes migration on
GICv3 ARMv8 server systems.

The changes include:
 - A fix related to the 32-bit idmap stub
 - A fix to the bitmask used to deode the operands of an AArch32 CP
   instruction
 - We have moved the files shared between arch/arm/kvm and
   arch/arm64/kvm to virt/kvm/arm
 - We add support for saving/restoring the virtual ITS state to
   userspace

The following changes since commit 1edb632133efb6226b6bef3e7d9fa8c7134ac4e2:

  ARM: KVM: Fix idmap stub entry when running Thumb-2 code (2017-04-20 20:17:57 +0200)
