This adds a generic uio driver that can bind to any PCI device. First

KVM would like to provide x2APIC interface to a guest without emulating
interrupt remapping device. The reason KVM prefers guest to use x2APIC
is that x2APIC interface is better virtualizable and provides better
performance than mmio xAPIC interface:

The following patch series includes all the patches I sent that have not been
applied yet. They are all rebased against the latest HEAD (including the recent
UUID patch).
Some new things are included too, such as a simple time drift test for Windows.
Sorry for posting so many commits at once.

checking for kvm_enabled() as does everybody else. It will make it
