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
