Subject: [PATCH for-stable-v4.4 47/53] ARM: make lookup_processor_type() non-__init

From: Ard Biesheuvel <[email-masked]>
Date: Tue, 5 Nov 2019 21:58:40 +0100

From: Russell King <[email-masked]>

Commit 899a42f836678a595f7d2bc36a5a0c2b03d08cbc upstream.

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