Hi, Keir,

Sorry for the xsave-introduced regression bug. I have fixed and
attached the patch with this email.
xsave-migration.patch contains all the changes you have reverted plus
the fix I made.
xsave-migration-fix.patch only contains the fix I made based on
original xsave patch series.

I have tested the patch in the following senarios:
1> Non-xsave platform
2> Xsave-capable platform, guest does not support xsave, xen support xsave
3> Xsave-capable platform, guest does support xsave, xen supports xsave
4> Guest (non-xsave) saved on platform without xsave, restored on a
Xsave-capable system.
All passed.

Could please have review? Thanks!

Again, sorry for the regression caused.
