A few remaining ARM patches, and a race condition fix that has had quite
a few eyes but I only managed to commit today due to some travelling
(commit 2230f9e1171a, "KVM: Avoid illegal stage2 mapping on invalid
memory slot").  The fix is relatively simple once you see it, and it's
been tested and reviewed thoroughly.

Paolo

----------------------------------------------------------------
ARM:

* Correctly save/restore PMUSERNR_EL0 when host userspace is using
  PMU counters directly

* Fix GICv2 emulation on GICv3 after the locking rework

* Don't use smp_processor_id() in kvm_pmu_probe_armpmu(), and
  document why

Generic:

* Avoid setting page table entries pointing to a deleted memslot if a
  host page table entry is changed concurrently with the deletion.
