From 14f087d839d9bd3f90ad69d4b3fde7d236c156b1 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 10 Apr 2012 12:39:55 +0900 Subject: [PATCH] sh: kgdb: Fix up basic SMP support. kgdb needs a kgdb_roundup_cpus() definition in the architecture backend, so just copy over the MIPS version, which already does what we want.
