Yes. Take a look in today's linux-next kernel (tag next-20100929)
for commit: 5d4bff94f9e0877a85b4dc573eb7a3f1d97c13ae

Essentially I just added an "unmask_irq()" call into the ->end
routine, renamed it, and used it as ->unmask.

It seems to work okay - I tried migrating interrupts around by
poking at /proc/irq/NNN/smp_affinity - and that still works.
