kvm-kmod-2.6.38-rc7

We are approaching 2.6.38, so it's time to role out a preview on its kvm bits:

No big news in this release (async page faults require a 2.6.38 host kernel), but many small improvements.

Major KVM changes since kvm-kmod-2.6.37:
- AMD Bulldozer virtualization extensions: instruction decode assist, clean bits, xsave/avx, flush-by-asid
- various small optimizations, e.g. of virtual MMU, x86 emulator, device assignment

kvm-kmod changes:
- Remove support for outdated kernels from compat anon_inode and srcu
- Drop unused request-irq-compat
