Control-flow Enforcement Technology (CET) provides protection against
return/jump-oriented programming (ROP) attacks. To make kvm Guest OS
own the capability, this patch-set is required. It enables CET related
CPUID report and xsaves/xrstors support etc in qemu.

Yang Weijiang (4):
  Add CET xsaves/xrstors related macros and structures.
  Add CET SHSTK and IBT CPUID feature-word definitions.
  Add hepler functions for CPUID xsave area size calculation.
  Report CPUID xsave area support for CET.
