Miscellaneous fixes and cleanups to emulator_error_test. The reason I
started looking at this test is because it fails when TDP is disabled,
which pollutes my test results wheneveer I am testing a new series for
upstream.

v2:
 - Split emulator_error_test into 2 separate tests to ensure continued
   test coverage of KVM emulation in response to EPT violations when
   "allow_smaller_maxphyaddr && guest.MAXPHYADDR < host.MAXPHADDR".  [Sean]
 - Test that flds generates #PF(RSVD) when TDP is disabled [Sean]

v1: https://lore.kernel.org/kvm/20220929204708.2548375-1-dmatlack@google.com/

David Matlack (8):
  KVM: selftests: Rename emulator_error_test to
    smaller_maxphyaddr_emulation_test
  KVM: selftests: Explicitly require instructions bytes
  KVM: selftests: Delete dead ucall code
  KVM: selftests: Move flds instruction emulation failure handling to
    header
  KVM: x86/mmu: Use BIT{,_ULL}() for PFERR masks
  KVM: selftests: Copy KVM PFERR masks into selftests
  KVM: selftests: Expect #PF(RSVD) when TDP is disabled
  KVM: selftest: Add a test for KVM_CAP_EXIT_ON_EMULATION_FAILURE
