[ Talking with Sebastian on IRC, it seems that doing the irq_work_run()
 from the interrupt in -rt is a bad thing. Here we simply raise the
 softirq if there's irq work to do. This too boots on my i7 ]

It is okay in general because most of the users should not run in bare
interrupt context. The only exception here is the nohz_full_kick_work
thing.

I know we discussed this on IRC, but I wanted to publicly state that
the missing irq work callback was the RCU's rsp_wakeup() function.
