Subject: [PATCH 2/9] arm64: mm: mark fault_info __ro_after_init
Date: Fri, 24 Mar 2017 07:46:25 -0700 [thread overview]
Message-ID: <20170324144632.5896-3-opendmb@gmail.com> (raw)
In-Reply-To: <20170324144632.5896-1-opendmb@gmail.com>
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.
