preempt=lazy has been merged into tip[1]. Lets Enable it for PowerPC.
This has been very lightly tested and as michael suggested could go
through a test cycle. If needed, patches can be merged. I have kept it
separate for easier bisect.
Lazy preemption support for kvm on powerpc is still to be done.

Hi mpe, maddy.
I see the lazy scheduling related changes are in powerpc tree.
If there are no objections, can we please add support for lazy
preemption so it goes through a cycle?
Let me know your thoughts.
