#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
#     
#     Pull KVM fixes from Paolo Bonzini:
#      "A collection of x86 and ARM bugfixes, and some improvements to
#       documentation.
#     
#       On top of this, a cleanup of kvm_para.h headers, which were exported
#       by some architectures even though they not support KVM at all. This is
#       responsible for all the Kbuild changes in the diffstat"
