From 7a768d30caa30e66ba89659f1845cc35b1bfc715 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 8 Feb 2012 18:11:01 +0000 Subject: [PATCH] powerpc/wsp: Fix IRQ affinity setting We call the cache_hwirq_map() function with a linux IRQ number but it expects a HW irq number. This triggers a BUG on multic-chip setups in addition to not doing the right thing.
