Also nice. I like the change. With my previous comment about pulling
the xen fragment into
the kernel itself, you'd be able to make these two lines consistent.

Moving up the chain to new kernels is simple after that, since I'll
pull it forward as I uprev
support. (in fact, we can also add a new 3.10 fragment along with
these changes now :)

Cheers,

Bruce
