From e085255ebce87c0b85d4752638d8a7d4f35f5b64 Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Tue, 10 May 2011 19:29:49 +0000 Subject: [PATCH] powerpc/xics: Cleanup xics_host_map and ipi Since we already have a special case in map to set the ipi handler, use the desired flow. If we don't find an ics to handle the interrupt complain instead of returning 0 without having set a chip or handler.
