It basically does that. All that we allow here is the architecture to
override the default order of what is considered priority.

The default (as per Power7) is naked cpu number, with lower cpu numbers
having higher priority to higher numbers.

This patch set allows the architecture to provide a less_than operator
(and through that a custom order).
