From e5a5de4447471ab1a01585f075400c2be36e2cb6 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 2 Apr 2015 23:58:55 +0100 Subject: [PATCH] ARM: enable ARM errata 643719 workaround by default The effects of not having ARM errata 643719 enabled on affected CPUs can be very confusing and hard to debug. Rather than leave this to chance, enable this workaround by default. Now that we have rearranged the code, it should have a low impact on the majority of CPUs.
