[Xen-devel] [PATCH 2/3 v2] XSAVE/XRSTOR: fix frozen states

["Han, Weidong" <weidong.han@xxxxxxxxx>]

If a guest sets a state and dirties the state, but later temporarily clears the 
state, and at this time if this vcpu is scheduled out, then other vcpus may 
corrupt the state before the vcpu is scheduled in again, thus the state cannot 
be restored correctly. To solve this issue, this patch save/restore all states 
unconditionally on vcpu context switch.
