Speaking of which. The 3ware drivers appear to have a bug
in their handling of this. They *always* report "handled=1"
from their interrupt routines, regardless of whether it was
their hardware or not that was signalling for attention.
Thanks for pointing this out, Mark.
What follows is a patch series to clean this up:
patch 1: only report IRQ_HANDLED when needed
patch 2: remove bogus "my irq == my irq" test
patch 3: fix indentation, after patch #2's change
