OK, here's what I have for kvm.  It matches the kernel patches I just
sent out, with the updated API.

I rewrote all the backwards compat stuff to wrap it in #ifdef
HORRIBLE_COMPAT_HACK, but something subtle broke and it no longer set
cpsr correctly for older kernels.  After wasting an afternoon on it, I
gave up and threw out the backwards compat code in digust.

Nor does it bisect, since we update the headers as you asked, then
update the code.

The following changes since commit 94d477a4017d45222a4a0227857ad9fc3f81fb2d:
