From e42a64002a507bf61e57106ed5323b1854371563 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 29 Sep 2020 06:48:33 +0000 Subject: powerpc: Remove CONFIG_PPC601_SYNC_FIX This config option isn't in any defconfig. The very first versions of Powerpc 601 have a bug which requires additional sync before and/or after some instructions. This was more than 25 years ago and time has come to retire those buggy versions of the 601 from the kernel.
