[PATCH 0/2] nVMX: Ensure host's PAT stays sane

[Sean Christopherson]

Fix a bug(s) where test_load_host_pat clobbers PAT and causes all
subsequent tests to effectively run with all memory mapped as UC.  Xiangfei
first noticed that this caused rdtsc_vmexit_diff_test to fail, but it can
also lead to timeouts if more tests are added, i.e. if more stuff runs after
test_load_host_pat.

Sean Christopherson (2):
  nVMX: Ensure host's PAT is loaded at the end of all VMX tests
  nVMX: Verify KVM actually loads the value in HOST_PAT into the PAT MSR
