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.
