#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
#     
#     Pull first set of KVM updates from Paolo Bonzini:
#      "PPC:
#        - minor code cleanups
#     
#       x86:
#        - PCID emulation and CR3 caching for shadow page tables
#        - nested VMX live migration
#        - nested VMCS shadowing
#        - optimized IPI hypercall
#        - some optimizations
#     
#       ARM will come next week"
