[PATCH] 2.6.11 does not handle IRQ #0 on IXP4xx ARM platforms

 The original get_irqnr_and_bse macro leave Z flag set when the IRQ
 being handled is #0, but the correct behaviour is to clear the flag
 when there is at least one IRQ to handle.

Best talk to the linux-arm-kernel list, which can be found
on http://www.arm.linux.org.uk/

There is also an linux-arm patch tracking system there where
you can submit fixes like that for the Linux/ARM community
to check.
