Yes,  that was an accident..  I just backed it out.

Its a local change I've been running with for months and never got
around to completing beyond isa and MFS'ing.  There's a problem in
that we disable interrupts in foo_teardown_intr() blindly, regardless
of if we are sharing them or not.  So when we unload a driver that
uses, say, irq 10, irq 10 is disabled and other devices sharing irq 10
starve.
