From f1f8926a94132e6433b559a3eced65404226f5cd Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 12 Feb 2008 17:00:39 +0900 Subject: [PATCH] sh: Update SH-5 flush_cache_sigtramp() for API changes. Previously this took an explicit range, update this to use the same behaviour as the rest of the SH parts where we simply flush out a line from the start address.
