Can't say I really like exporting it as all users will need a major
ifdef mess.  If at all we'd expose the higher level add to llist and ipi
abstraction that both blk-mq and the null_blk driver use.

For now I'd just suggest removing the NULL_IRQ_SOFTIRQ mode from
null_blk and decouple that from blk-mq itself.  I'll try to cook up such
an abstraction in the meantime.
