[PATCH v3 0/3] idle improvements again

[Nicholas Piggin]

Since last time, this has been rebased on top of the KVM / SMT4
forcing changes. It has also been updated so as to not disable
EC=ESL=0 idle states for CPU unplug.

That case (and powersave=off) continues to be broken for KVM with
unplugged dependent secondaries, but that's another issue.

This also has EC=ESL=0 states to skip the new hwsync added for the
KVM workaround, which should increase their performance advantage a
little further.

Thanks,
Nick

  powerpc/64s/idle: POWER9 implement a separate idle stop function for
    hotplug
  powerpc/64s/idle: avoid sync for KVM state when waking from idle
  powerpc/64s/idle: POWER9 ESL=0 stop avoid save/restore overhead
