Subject: [PATCH] powerpc/wsp: Fix IRQ affinity setting
Date: Thu, 09 Feb 2012 15:11:01 +1100 [thread overview]
Message-ID: <1328760661.2903.49.camel@pasglop> (raw)
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.
