Linus, please pull from
git://git.kernel.org/pub/scm/virt/kvm/kvm.git kvm-updates/2.6.33
to receive the KVM updates for the 2.6.33 merge window.
Highlights:
- improved kernel context switching speed
- better interoperation with other users of virtualization extensions
- improved irq scaling
- nested svm improvements and tracing
- improved cpufreq integration
- spin loop detection on newer hardware
Notes:
- this update depends on, and thus merges, tip's x86/entry branch (user
return notifiers)
- kvm/ppc64 support will be merged through the powerpc tree
