#     Pull kvm fixes from Paolo Bonzini:
#      "x86:
#     
#        - Fixes for Xen emulation. While nobody should be enabling it in the
#          kernel (the only public users of the feature are the selftests),
#          the bug effectively allows userspace to read arbitrary memory.
#     
#        - Correctness fixes for nested hypervisors that do not intercept INIT
#          or SHUTDOWN on AMD; the subsequent CPU reset can cause a
#          use-after-free when it disables virtualization extensions. While
#          downgrading the panic to a WARN is quite easy, the full fix is a
#          bit more laborious; there are also tests. This is the bulk of the
#          pull request.
#     
#        - Fix race condition due to incorrect mmu_lock use around
#          make_mmu_pages_available().
#     
#       Generic:
#     
#        - Obey changes to the kvm.halt_poll_ns module parameter in VMs not
#          using KVM_CAP_HALT_POLL, restoring behavior from before the
#          introduction of the capability"
