[Xen-devel] [PATCH] Mask off the reserved features in cpuid (ecx = 1)
The patch prevents new potential features from being exposed to the guests when not virtualized properly. Guests can attempt to set the control registers, etc. (and get #GP and panic) if they are aware of the new feature and the cpuid says it''s available.
