From 05c74a6cbcfb416286a947668ba32f63d99fe74a Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 3 Dec 2010 11:09:48 +0000 Subject: ARM: SMP: consolidate the common parts of smp_prepare_cpus() There is a certain amount of smp_prepare_cpus() which doesn't belong in the platform support code - that is, code which is invariant to the SMP implementation. Move this code into arch/arm/kernel/smp.c, and add a platform_ prefix to the original function.
