This is entirely s390x. The STFLE is an instruction: "STore Facility List Extented". ------- Comment From brueck...@de.ibm.com 2016-03-16 04:07 EDT------- (In reply to comment #5) > How about a backport to v4.4 ?

To cleanly apply the required patch, please also apply the below one first: commit 76cdd44c2e56ffabc297494c090c6babc8985998 Author: Heiko Carstens <heiko.carst...@de.ibm.com> Date: Tue Nov 24 12:33:07 2015 +0100 s390/facilities: always use lowcore's stfle field for storing facility bits head.s contains an stfle instruction which stores it result at the storage location that is assigned to the stfl instruction. This is currently no problem, since we only care about one double word. However if the number of double words in the ALS bitfield grows the current code is not very stable. E.g. before issuing the stfle command the memory to which it stores must be cleared, since the instruction may or may not clear memory contents where no bits are set. In order to simplify the code a bit always use the storage location that we reserved for the stfle result.
