Hi!
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.
