x86/msr-index: Add MSRs for XFD
XFD introduces two MSRs: - IA32_XFD to enable/disable a feature controlled by XFD - IA32_XFD_ERR to expose to the #NM trap handler which feature was tried to be used for the first time. Both use the same xstate-component bitmap format, used by XCR0. Signed-off-by: NChang S. Bae <chang.seok.bae@intel.com> Signed-off-by: NThomas Gleixner <tglx@linutronix.de> Signed-off-by: NChang S.
