X86: implement PCID/INVPCID for hvm This patch handle PCID/INVPCID for hvm: For hap hvm, we enable PCID/INVPCID, since no need to intercept INVPCID, and we just set INVPCID non-root behavior as running natively; For shadow hvm, we disable PCID/INVPCID, otherwise we need to emulate INVPCID at vmm by setting INVPCID no...
