I found some issues with kvm-kmod from recently pulled tree on F13
(2.6.33) kernel. I am not 100% sure the version numbers are right in
all of these fixes, but at least it compiles and seems to run VMs again.
The FPU change and the iommu change are, well, rather scary. They could
use some eyes and suggestions.

Well, this apparently doesn't work. The module builds, load, and runs
non-paging mode fine, but things appear to go haywire just around when
paging gets activated. Any recent changes in the module (large page,
TLB contract) that might be relying on addition kernel support?
Or just too long since I pulled mainline. I'll try a bsect and see
where I get.

Thanks a lot for the patches! Just yesterday, I finally started hacking
on this as well. I have some FPU wrapper running (see next branch) that
seems to run fine - but is in some parts also more complicated as
required (and has a build problem on very old kernels).
Will comment on individual patches.
