Yes, there's a lot of stuff on that line which will not bisect well;
there were substantial changes to percpu data handling, and a change to
some of the core pvops calling conventions.  It will take care to choose
good bisection points to narrow things down.

But it also sounds like it could be on the Xen side.  Would it be
possible to try and narrow down where Xen stops breaking?
