From 0a301110b7bd33ef10164c184fe2c1d8c4c3ab6b Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 14 Jan 2013 15:54:28 +0000 Subject: [PATCH] ARM: smp: remove wrapper functions Remove some silly wrapper functions which aren't really required: platform_smp_prepare_cpus platform_secondary_init platform_cpu_die This simplifies the code.
