that's rather impressive and looks nice, considering the fairly low
impact.

as there were no fundamental objections in this thread i've created a
tip/x86/paravirt-spinlocks topic branch for these patches and started
testing them.

i based the topic branch on tip/xen-64bit, so you should be able to get
the latest code by doing:

git-merge tip/x86/paravirt-spinlocks

on tip/master.
