[PATCH 4.4 67/75] ARM: make lookup_processor_type() non-__init

From: Greg Kroah-Hartman
Date: Fri Nov 08 2019 - 13:55:19 EST


From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>

Commit 899a42f836678a595f7d2bc36a5a0c2b03d08cbc upstream.

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