Subject: rcu: add __cpuinit to rcu_init_percpu_data()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e4fa4c97016037620f9dc8bafe03e1086b665b4c;p=linux-beck.git

rcu: add __cpuinit to rcu_init_percpu_data()

Impact: reduce memory footprint

add __cpuinit to rcu_init_percpu_data(), and this function's text
will be discarded after boot when !CONFIG_HOTPLUG_CPU.
