Subject: [PATCH 2/9] arm64: mm: mark fault_info __ro_after_init

From: [email-masked] (Doug Berger)
Date: Fri, 24 Mar 2017 07:46:25 -0700

The fault_info table must be made writeable to allow installation
of custom memory abort handlers, but it can be made read-only
after initialization to provide some protection.
