This doesn't seem right.

This driver seem to try and move interrupts on its own when the CPU
goes down. Why can't it rely on the normal CPU hotplug infrastructure
to do so like all the other drivers (bar some Cavium driver that does
the same thing)?

I'd rather you take this opportunity to move these drivers into the
21st century, so that we can kill irq_cpu_offline() and co altogether.

Thanks,

	M.
