  KVM: selftests: allow two iterations of dirty_log_perf_test (2020-11-09 09:45:17 -0500)

----------------------------------------------------------------
ARM:
- Fix compilation error when PMD and PUD are folded
- Fix regression in reads-as-zero behaviour of ID_AA64ZFR0_EL1
- Add aarch64 get-reg-list test

x86:
- fix semantic conflict between two series merged for 5.10
- fix (and test) enforcement of paravirtual cpuid features

Generic:
- various cleanups to memory management selftests
- new selftests testcase for performance of dirty logging

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

In case the selftests changes are too big, I placed them on top so they
can easily be deferred to 5.11.

Thanks,

Paolo
