From 9863a0babc2f0d920dfb4ddecf4e5b5342cb986b Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Mon, 16 Mar 2009 17:54:49 +1000 Subject: [PATCH] m68k: merge the non-MMU and MMU versions of swab.h It is trivial to merge the non-MMU and MMU versions of swab.h. Without a single file "make headers_install" is broken for m68k (since each of the sub-varients of swab.h are not installed).
