selftests: kvm: fix overlapping addresses in memslot_perf_test (2021-05-29 06:28:06 -0400)

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