Date: Wed, 17 Mar 2010 19:10:55 +0100 From: Joakim Tjernlund <Joakim.Tjernlund@...nsmode.se> To: LKML <linux-kernel@...r.kernel.org> Cc: Joakim Tjernlund <Joakim.Tjernlund@...nsmode.se> Subject: [PATCH] [RFC] #define __BYTE_ORDER Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. This patch has not been tested so watch out for breakage.
