From 9205b797dbe519a629267ec8c5766cd973d35063 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 24 Aug 2015 21:49:30 +0100 Subject: [PATCH] ARM: 8421/1: smp: Collapse arch_cpu_idle_dead() into cpu_die() The only caller of cpu_die() on ARM is arch_cpu_idle_dead(), so let's simplify the code by renaming cpu_die() to arch_cpu_idle_dead(). While were here, drop the __ref annotation because __cpuinit is gone nowadays.
