I build and booted these patches against tip/master as of this morning.
It build ~50 defconfig kernels on my WSM-EP.

I've not managed to reproduce the hang as reported by Dave, but then I
doubt building kernels has anywhere near the lock contention he
generated.

I did run my userspace on both the WSM-EP as well as the Interlagos box,
topping out at 24 and 32 contending cpus resp.

No weird lockups :/
