From: Christian Borntraeger Date: Fri, 19 Sep 2014 13:46:02 +0000 (+0200) Subject: s390/head.s: use zero as address for stfl X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b881dcfbf7fd89b2be801843b060b9ad77cc77e7;p=linux-beck.git s390/head.s: use zero as address for stfl The architecture suggests to use address 0 as parameter for stfl, to allow for future extensions. Using __LC_STFL_FAC_LIST (0x200) shows which address is used, but might be not future proof.
