Subject: [PATCH] powerpc: mpic: minor optimization of ipi handler
Date: Fri, 19 Oct 2007 13:51:10 -0500 [thread overview]
Message-ID: <20071019185110.GA11911@lixom.net> (raw)
Jeff Garzik pointed out that we don't actually have to lookup the mpic
instance since it's passed in as the interrupt handler data for IPIs.
