[Xen-devel] [PATCH RFC v1 02/74] x86: Common cpuid faulting support

From: Andrew Cooper With CPUID Faulting offered to SVM guests, move Xen's faulting code to being common rather than Intel specific. This is necessary for nested Xen (inc. pv-shim mode) to prevent PV guests from finding the outer HVM Xen leaves via native cpuid.
