This patch comes from the kvm tree and fixes the timer IRQ routing for
me which is broken from the POV of certain Linux guest kernels. As I'm
not up-to-date with the development around that problematic hunk, I'm
leaving it to someone more deeply involved to sign this off. But please
commit some fix.
Thanks,
Jan

we don't support it yet (need bios support, and modifications to kernel
irq routing).
