Hi,

The hypervisor doorbells are used by skiboot and Linux on POWER9
processors to wake up secondaries. This adds processor control support
to the Book3S architecture.

The full tree can be found here :

Thanks,

1 & 2 look like correct fixes regardless of anything else, so I've
applied them.  Still looking at 3/3.
