From 8a03e81cb14712f986c5d5fa42a30ff2cbe3237c Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Wed, 26 Sep 2018 14:24:30 +0200 Subject: [PATCH] powerpc/64s: consolidate MCE counter increment. The code in machine_check_exception excludes 64s hvmode when incrementing the MCE counter only to call opal_machine_check to increment it specifically for this case. Remove the exclusion and special case. Fixes: a43c1590426c ("powerpc/pseries: Flush SLB contents on SLB MCE errors.")
