[Xen-devel] Re: [Patch 0/3] Refining Xsave/Xrestore support - Version 3

[Haitao Shan <maillists.shan@xxxxxxxxx>]

Hi, Keir,

Can you pull the 4 xsave-related patches to Xen4.0 tree?
I have tried. Applying the patches is quite straight forward. Patch 4
needs some minor modifications since there are some general function
changes recently in unstable tree (while these are not in Xen4.0). I
have made this for you.
All patches are Signed-off-by: Haitao Shan <haitao.shan@xxxxxxxxx> and
Han Weidong <weidong.han@xxxxxxxxx>

Thanks!

Shan Haitao
