Right.  tglx has removed these changes from tip.git (even though they
were OK), and I've reinstated the proper versions in my tree.  The
xen.git on git.kernel.org still has old versions, but I'll sort that out
once it's back online.  I expect it will ultimately go upstream via
tip.git, but we can work that out later too.
