This is broken -- you do want to check bit #7 for spurious interrupts instead of doing awkward PIC poking. Alternatively, just skip the check -- the condition is rare and handlers need to be able to deal with it anyway. It was discussed a few months ago and I proposed a correct patch similar to your one, but it was rejected, sigh... -- + Maciej W.
