Subject: [PATCH] 2.6.11 does not handle IRQ #0 on IXP4xx ARM platforms
Date: Sat, 12 Mar 2005 20:03:58 +0100 [thread overview]
Message-ID: <20050312190358.GA14440@mobile> (raw)
[-- Attachment #1: Type: text/plain, Size: 261 bytes --]
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.
