kvm-kmod-2.6.36-rc6

The KVM development for 2.6.36 settled, so it's time to role out the first kvm-kmod test version based on that kernel. The changelog might be a bit boring - I was too lazy to dig for potential interesting details.

Major KVM changes since kvm-kmod-2.6.35.6:
- "No major features: mostly improved mmu and emulator correctness, some performance improvements, and support for guest XSAVE and AVX." [Avi]

kvm-kmod changes:
- Warn about TXT conflict on kernels < 2.6.35
- Remove some wrapping code for unsupported host kernels
