From 06d8a10a70b7ef14ebf88b874858f73f2dee1109 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Fri, 3 Sep 2021 17:55:04 +0200 Subject: s390x/tcg: convert real to absolute address for RRBE, SSKE and ISKE For RRBE, SSKE, and ISKE, we're dealing with real addresses, so we have to convert to an absolute address first. In the future, when adding EDAT1 support, we'll have to pay attention to SSKE handling, as we'll be dealing with absolute addresses when the multiple-block control is one.
