How would you deal with per-cpu kernel threads (softirqs, etc.) or
softirq processing while in the kernel?

If you have pinned an interrupt to that CPU then you need to process
the softirq for it as well. If that's the device your very single user
space thread is talking to then you better want that, if you are not
interested then simply pin that device irq to some other CPU: no irq
-> no softirq.

Ah, okay.  For some reason I had thought that the incoming work was
queued up globally and might be handled by any softirq.
