[Xen-devel] [PATCH 2/5][RFC] lwp: adding support for AMD lightweight profiling
Add a new field for xsave/xrstor functions to specify the features. Current implementation set EAX:EDX to all 1''s. To be prepared for LWP, we add a parameter in xsave/xrstor functions to be set in EAX:EDX. Some of the idea was borrowed from Hans Rosenfeld''s Linux kernel patch.
