From 93c10d3d68c469c1addacbc541da5518f1de021d Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 27 Oct 2010 17:28:43 +0100 Subject: MN10300: Reorder asm/cacheflush.h to put primitives first Reorder asm/cacheflush.h to put arch primitives first, before the main functions so that the main functions can be inline asm rather than #defines when non-trivial.
