From b6c2dbd7214b0b2396e1dcf9668c8b48ab571115 Mon Sep 17 00:00:00 2001 From: Janosch Frank Date: Thu, 27 Feb 2020 04:23:41 -0500 Subject: [PATCH] s390x: Rename and use constants for short PSW address and mask Let's rename PSW_MASK_ESA_ADDR to PSW_MASK_SHORT_ADDR because we're not working with a ESA PSW which would not support the extended addressing bit. Also let's actually use it. Additionally we introduce PSW_MASK_SHORT_CTRL and use it throughout the codebase.
