From bce133ab7d4c4799949478fc7897cc335f3042e9 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 20 Mar 2017 14:29:50 +0100 Subject: s390/facilites: use stfle_fac_list array size for MAX_FACILITY_BIT 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.
