[PATCH 00/39] KVM updates for the 2.6.34 merge window (batch 2/4)

[Avi Kivity]

This is the first of four batches of patches for the 2.6.34 merge window.  KVM
changes for this cycle include:

 - rdtscp support
 - powerpc server-class updates
 - much improved large-guest scaling (now up to 64 vcpus)
 - improved guest fpu handling
 - initial Hyper-V emulation
 - better swapping with EPT
 - 1GB pages on Intel
 - x86 emulator fixes

as well as the usual assortment of random fixes and improvements.
