The mismatch to IRQ count ratio looks sane.

It is already present in 2.4.2-ac3.

There is a small performance impact at every interrupt -- the code that
checks for mismatches incurs it. It's just a few CPU instructions, thus
it should not be noticeable.

Please do. I believe the code is safe to be included in 2.4.3, but if
any problem is going to pop up, it'd better do it before than after
applying to the mainstream.
