Hmm, seems to be a rather bad timing for the series of Vitaly.

What is the best way to resolve those conflicts? A rebase of Vitaly's
patches seems to be required in any case.

Should I rebase the Xen tree on current tip? This seems to be rather
easy, but I think this will work only if I can be sure the current tip
tree contents will all be merged by Linus before the Xen tree.

I could try to cherry pick the patches from tip where Vitaly's patches
have conflicts with, but I think this could lead to a lot of patches
to take.

Or we could delay Vitaly's series until tip has been merged, but this
will either delay some other Xen patches depending on (or conflicting
with) Vitaly's patches or would make the rebase for Vitaly more
difficult.

Thoughts?
