See http://www.infradead.org/rpr.html Sender: linux-mips-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-mips@vger.kernel.org The SuperH implementation of flush_icache_range seems to be able to cope with user addresses. Just define flush_icache_user_range to flush_icache_range.
