Series selftests: KVM: verify page stats in kvm x86/mmu | expand

This patch set leverages the existing dirty logging performance selftest to
verify whether the page stats work correctly in KVM x86/mmu especially with
the consequence of dirty logging.

v2 -> v3:
 - fix the build error. [mizhang]

v1 -> v2:
 - split the page alignment fix into a different commit [bgardon]
 - update the TEST_ASSERT conditions [bgardon]

Mingwei Zhang (2):
  selftests: KVM: align guest physical memory base address to 1GB
  selftests: KVM: use dirty logging to check if page stats work
