Hi folks,
My first attempt to send out a patch series with git ...
The patches fix the kvm paravirt clocksource code to be compatible with
xen and they also factor out some code which can be shared into a
separate source files used by both kvm and xen.

I am not certain of this, but it seems like this patch leaves things in
a somewhat asymetric state. At the very least, I think that asymetry
should be documented in the comments of either mmu_notifier.h or .c.
