[RFC][PATCH 0/7] Fix the scheduler-IPI mess.

So commit: 90b5363acd47 ("sched: Clean up scheduler_ipi()") is pretty buggered, and
I'm afraid this is the 'prettiest' pile of puke I could come up with.
It boots and builds a kernel, but it already did that for me.
I do think there's definite room for further integration of smp_function_call
and irq_work, but figured this was quite enough for now.
Please look hard, there be dragons here, I'm sure.
