kvm/selftests/memslots_perf_test doesn't work with 64KB-page-size-host
and 4KB-page-size-guest on aarch64. In the implementation, the host and
guest page size have been hardcoded to 4KB. It's ovbiously not working
on aarch64 which supports 4KB, 16KB, 64KB individually on host and guest.
This series tries to fix it. After the series is applied, the test runs
successfully with 64KB-page-size-host and 4KB-page-size-guest.
# ./memslots_perf_tests -v -s 512
Since we're here, the code is cleaned up a bit as PATCH[1-3] do. The
other patches are fixes to handle the mismatched host/guest page
sized.
