#     powerpc: fix hardware PMU exception bug on PowerVM compatibility mode systems
#     
#     PowerVM systems running compatibility mode on a few Power8 revisions are
#     still vulnerable to the hardware defect that loses PMU exceptions arriving
#     prior to a context switch.
#     
#     The software fix for this issue is enabled through the CPU_FTR_PMAO_BUG
#     cpu_feature bit, nevertheless this bit also needs to be set for PowerVM
#     compatibility mode systems.
#     
#     Fixes: 68f2f0d431d9ea4 ("powerpc: Add a cpu feature CPU_FTR_PMAO_BUG")
