Subject: [PATCH 4.9 10/16] ARM: make lookup_processor_type() non-__init

From: Russell King <rmk+kernel@...linux.org.uk>

Commit 899a42f836678a595f7d2bc36a5a0c2b03d08cbc upstream.

Move lookup_processor_type() out of the __init section so it is callable
from (eg) the secondary startup code during hotplug.
