From 93e27aae8460e464e04cf5cfa387bac8947f941a Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 4 Apr 2016 10:55:36 -0700 Subject: MIPS: BMIPS: local_r4k___flush_cache_all needs to blast S-cache commit f675843ddfdfdf467d08cc922201614a149e439e upstream. local_r4k___flush_cache_all() is missing a special check for BMIPS5000 processors, we need to blast the S-cache, just like other MTI processors since we have an inclusive cache. We also need an additional __sync() to make sure this is completed.
