From e5c14ce118ab6a96afb2af5c4ec9727b03ab1936 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 17 Aug 2006 03:59:27 +0200 Subject: [POWERPC] Fix irq radix tree remapping typo The code for using the radix tree for reverse mapping of interrupts has a typo that causes it to create incorrect mappings if the software and hardware numbers happen to be different. This would, among others, cause the IDE interrupt to fail on js20's. This fixes it.
