#     powerpc/64s: Fix DT CPU features Power9 DD2.1 logic
#     
#     In the device tree CPU features quirk code we want to set
#     CPU_FTR_POWER9_DD2_1 on all Power9s that aren't DD2.0 or earlier. But
#     we got the logic wrong and instead set it on all CPUs that aren't
#     Power9 DD2.0 or earlier, ie. including Power8.
#     
#     Fix it by making sure we're on a Power9. This isn't a bug in practice
#     because the only code that checks the feature is Power9 only to begin
#     with. But we'll backport it anyway to avoid confusion.
#     
#     Fixes: 9e9626ed3a4a ("powerpc/64s: Fix POWER9 DD2.2 and above in DT CPU features")
