Subject: [PATCH 4.9 32/32] s390/facilites: use stfle_fac_list array size for MAX_FACILITY_BIT
Date: Tue, 8 May 2018 10:11:12 +0200 [thread overview]
Message-ID: <20180508074013.907510255@linuxfoundation.org> (raw)
In-Reply-To: <20180508074008.800421598@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <heiko.carstens@de.ibm.com>
commit 6f5165e864d240d15675cc2fb5a369d57e1f60d0 upstream.
Use the actual size of the facility list array within the lowcore
structure for the MAX_FACILITY_BIT define instead of a comment which
states what this is good for. This makes it a bit harder to break
things.
