From f07f21b3e20c11017cea17ec841f0150a62aac53 Mon Sep 17 00:00:00 2001 From: Sascha Silbe Date: Wed, 4 Nov 2015 14:16:57 +0100 Subject: [PATCH] s390/sclp: _sclp_wait_int(): retain full PSW mask There's no reason to clear all PSW mask bits other than the addressing mode bits. Just use the previous PSW mask as-is.
