From 0f62bf633f287b8e9af1384d0ef1857fc5e8363e Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Mon, 28 Nov 2016 00:15:14 +0200 Subject: [PATCH] sh4: cache: correct flush_cache() to writeback and invalidate In common usecases flush_cache() assumes both cache invalidation and write-back to memory, instead of doing cache invalidation only with the wrapped 'ocbi' instruction pin flush_cache() to cache invalidation with memory write-back done by 'ocbp'.
