Pull kvm fixes from Paolo Bonzini:
 "ARM:

   - Rework heuristics for resolving the fault IPA (HPFAR_EL2 v. re-walk
     stage-1 page tables) to align with the architecture. This avoids
     possibly taking an SEA at EL2 on the page table walk or using an
     architecturally UNKNOWN fault IPA

   - Use acquire/release semantics in the KVM FF-A proxy to avoid
     reading a stale value for the FF-A version

   - Fix KVM guest driver to match PV CPUID hypercall ABI

   - Use Inner Shareable Normal Write-Back mappings at stage-1 in KVM
     selftests, which is the only memory type for which atomic
     instructions are architecturally guaranteed to work

  s390:

   - Don't use %pK for debug printing and tracepoints

  x86:

   - Use a separate subclass when acquiring KVM's per-CPU posted
     interrupts wakeup lock in the scheduled out path, i.e. when adding
     a vCPU on the list of vCPUs to wake, to workaround a false positive
     deadlock. The schedule out code runs with a scheduler lock that the
     wakeup handler takes in the opposite order; but it does so with
     IRQs disabled and cannot run concurrently with a wakeup

   - Explicitly zero-initialize on-stack CPUID unions

   - Allow building irqbypass.ko as as module when kvm.ko is a module

   - Wrap relatively expensive sanity check with KVM_PROVE_MMU

   - Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses

  selftests:

   - Add more scenarios to the MONITOR/MWAIT test

   - Add option to rseq test to override /dev/cpu_dma_latency

   - Bring list of exit reasons up to date

   - Cleanup Makefile to list once tests that are valid on all
     architectures

  Other:

   - Documentation fixes"
