[PATCH 0/3] lockde,sched: Better pinning

[Peter Zijlstra]

I've been sitting on these patches for a long while and finally got around to
finishing them.

They implement a better pinning, as requested by Ingo. I'm not entirely sure I
like what 2/3 does, but it does avoid extra code bloat, where all other
attempts resulted in changed code for !lockdep.
