Subject: [PATCH] ARM: smp: Collapse arch_cpu_idle_dead() into cpu_die()
Date: Fri, 14 Aug 2015 00:58:59 -0700 [thread overview]
Message-ID: <1439539139-8783-1-git-send-email-sboyd@codeaurora.org> (raw)
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.
