Nunes do Rosario # Date: Thu Feb 27 10:47:15 2020 -0300 # # 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") # Signed-off-by: Desnes A.
