Merge tag 'kvm-arm-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2019-07-11 15:14:16 +0200)

----------------------------------------------------------------

ARM:
* support for chained PMU counters in guests
* improved SError handling
* handle Neoverse N1 erratum #1349291
* allow side-channel mitigation status to be migrated
* standardise most AArch64 system register accesses to msr_s/mrs_s
* fix host MPIDR corruption on 32bit
* selftests ckleanups

x86:
* PMU event {white,black}listing
* ability for the guest to disable host-side interrupt polling
* fixes for enlightened VMCS (Hyper-V pv nested virtualization),
* new hypercall to yield to IPI target
* support for passing cstate MSRs through to the guest
* lots of cleanups and optimizations

Generic:
* Some txt->rST conversions for the documentation
