#     
#     Pull KVM fixes from Paolo Bonzini:
#      "ARM:
#     
#        - Avoid dropping the page refcount twice when freeing an unlinked
#          page-table subtree.
#     
#        - Don't source the VFIO Kconfig twice
#     
#        - Fix protected-mode locking order between kvm and vcpus
#     
#       RISC-V:
#     
#        - Fix steal-time related sparse warnings
#     
#       x86:
#     
#        - Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int"
#     
#        - Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if
#          and only if the incoming events->nmi.pending is non-zero. If the
#          target vCPU is in the UNITIALIZED state, the spurious request will
#          result in KVM exiting to userspace, which in turn causes QEMU to
#          constantly acquire and release QEMU's global mutex, to the point
#          where the BSP is unable to make forward progress.
#     
#        - Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl
#          being incorrectly truncated, and ultimately causes KVM to think a
#          fixed counter has already been disabled (KVM thinks the old value
#          is '0').
#     
#        - Fix a stack leak in KVM_GET_MSRS where a failed MSR read from
#          userspace that is ultimately ignored due to ignore_msrs=true
#          doesn't zero the output as intended.
#     
#       Selftests cleanups and fixes:
#     
#        - Remove redundant newlines from error messages.
#     
#        - Delete an unused variable in the AMX test (which causes build
#          failures when compiling with -Werror).
#     
#        - Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails
#          with an error code other than ENOENT (a Hyper-V selftest bug
#          resulted in an EMFILE, and the test eventually got skipped).
#     
#        - Fix TSC related bugs in several Hyper-V selftests.
#     
#        - Fix a bug in the dirty ring logging test where a sem_post() could
#          be left pending across multiple runs, resulting in incorrect
#          synchronization between the main thread and the vCPU worker thread.
#     
#        - Relax the dirty log split test's assertions on 4KiB mappings to fix
#          false positives due to the number of mappings for memslot 0 (used
#          for code and data that is NOT being dirty logged) changing, e.g.
#          due to NUMA balancing"
