It could go back a lot farther than that. I don't think our interrupt
setup has been changed significantly for a long time, with one
exception: We added the IRQF_DISABLED flag fairly recently. But of
course, we now know that it doesn't do what we expected.
It's surprising that more people haven't experienced this problem and
reported it.

There still are a few places where spaces were used instead of tabs for
indenting. Aside from that it looks fine.
