From c982c6d6c48b48159db481581cadbb8773219677 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Thu, 9 Jul 2015 10:40:50 +0100 Subject: [PATCH] MIPS: cpu-probe: Remove cp0 hazard barrier when enabling the FTLB We are so early in the boot process where we really don't want to stall and wait for CP0 FTLB related changes become visible so just drop the cp0 hazard barrier.
