#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
#     
#     Pull kvm fixes from Paolo Bonzini:
#      "It's a bit larger than I (and probably you) would like by the time we
#       get to -rc6, but perhaps not entirely unexpected since the changes in
#       the last merge window were larger than usual.
#     
#       x86:
#        - Fixes for missing TLB flushes with TDP MMU
#     
#        - Fixes for race conditions in nested SVM
#     
#        - Fixes for lockdep splat with Xen emulation
#     
#        - Fix for kvmclock underflow
#     
#        - Fix srcdir != builddir builds
#     
#        - Other small cleanups
#     
#       ARM:
#        - Fix GICv3 MMIO compatibility probing
#     
#        - Prevent guests from using the ARMv8.4 self-hosted tracing
#          extension"
