| |
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
