From 4a7a0a8444ba4cebb3a6744e9c14fc6391d7f266 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 26 Jul 2018 23:07:02 +1000 Subject: [PATCH] powerpc/64s: Move SET_SCRATCH0() into EXCEPTION_PROLOG_PSERIES() EXCEPTION_PROLOG_PSERIES() only has two users, STD_EXCEPTION_PSERIES() and STD_EXCEPTION_HV() both of which "call" SET_SCRATCH0(), so just move SET_SCRATCH0() into EXCEPTION_PROLOG_PSERIES().
