  : KVM memslot selftest fixes for non-4kB page sizes, courtesy
  : of Gavin Shan. From the cover letter:
  :
  : "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."
