[PATCH 00/42] KVM updates for the 2.6.33 merge window (batch 1/2)

[Avi Kivity <avi@redhat.com>]

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:
- kvm/ppc64 support will be merged through the powerpc tree
- depends on tip x86/entry branch (user return notifiers)
