Its unfortunate that you prefer these dinky little hacks over helping
out providing whatever infrastructure you need.

There's plenty good reasons for mandating that irq handlers run with
irqs disabled, if you need threaded handlers -- that's fine, but then
teach the generic code about them.

What you do _NOT_ do is hack your way around things, that's not how
Linux works, and by doing that you make the world a slightly worse place
for everyone.
