Change logs from v1 -> v2: Due to not guarantee backward

That's OK for review but we can't apply the rest of these patches
without the save/restore one; it'll just silently break save/restore for
HVM guests.

XSAVE/XRSTOR was already enabled by Dexuan for months, but it misses save/restore xstates. Actually it already breaks hvm guests save/restore on platforms which supports XSAVE/XRSTOR.

Weidong
