Pull KVM fixes from Paolo Bonzini:
"ARM fixes:
- Another state update on exit to userspace fix
- Prevent the creation of mixed 32/64 VMs
- Fix regression with irqbypass not restarting the guest on failed
connect
- Fix regression with debug register decoding resulting in
overlapping access
- Commit exception state on exit to usrspace
- Fix the MMU notifier return values
- Add missing 'static' qualifiers in the new host stage-2 code
x86 fixes:
- fix guest missed wakeup with assigned devices
- fix WARN reported by syzkaller
- do not use BIT() in UAPI headers
- make the kvm_amd.avic parameter bool
PPC fixes:
- make halt polling heuristics consistent with other architectures
selftests:
- various fixes
- new performance selftest memslot_perf_test
- test UFFD minor faults in demand_paging_test"
