The patch applies to the mainstream kernel, so seems there's difference between tip and the mainstream kernel. I will try to find the difference. And there's another patch for Xen, but I found the mail tile is wrong:( Please refer to: http://www.kernelhub.org/?msg=373208&p=2 Should I merge the patch for xen with the patch for native x86? Is there any dependency between them? Thanks!

You need to also kill XEN_CALL_FUNCTION_SINGLE_VECTOR which > is either part of a different patch or against a different tree.
