Since v2: Split up the features into two patches.

I kept Vaidy's reviewed-by because the end result code was not changed.

Nicholas Piggin (3):
  powerpc: add POWER9_DD20 feature
  powerpc/64s/idle: avoid POWER9 DD1 and DD2.0 ERAT workaround on DD2.1
  powerpc/64s/idle: avoid POWER9 DD1 and DD2.0 PMU workaround on DD2.1
