#     selftests/powerpc: Fix L1D flushing tests for Power10
#     
#     The rfi_flush and entry_flush selftests work by using the PM_LD_MISS_L1
#     perf event to count L1D misses.  The value of this event has changed
#     over time:
#     
#     - Power7 uses 0x400f0
#     - Power8 and Power9 use both 0x400f0 and 0x3e054
#     - Power10 uses only 0x3e054
#     
#     Rather than relying on raw values, configure perf to count L1D read
#     misses in the most explicit way available.
#     
#     This fixes the selftests to work on systems without 0x400f0 as
#     PM_LD_MISS_L1, and should change no behaviour for systems that the tests
#     already worked on.
#     
#     The only potential downside is that referring to a specific perf event
#     requires PMU support implemented in the kernel for that platform.
