This is a set of tests that checks KVM and CPU behaviour in regard to
canonical checks of various msrs, segment bases, instructions that
were found to ignore CR4.LA57 on CPUs that support 5 level paging.

Best regards,

Maxim Levitsky (5):
  x86: add _safe and _fep_safe variants to segment base load
    instructions
  x86: add a few functions for gdt manipulation
  x86: move struct invpcid_desc descriptor to processor.h
  Add a test for writing canonical values to various msrs and fields
  nVMX: add a test for canonical checks of various host state vmcs12
    fields.
