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.

Hello,
I've been trying to get your msr-ops linux-kvm & qemu branches to work, but so far I've not had any luck booting a guest. I'll nuke my setup and start over tomorrow to make sure I don't have something broken. Are there any known issues with the code so far?
Cheers,
Antonios
