4.2.8-ckt12 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Florian Fainelli <f.fainelli@xxxxxxxxx> 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.
