Port over new le32_add_cpu & friends changes from OCFS2 to core move.
The patch:
commit 8b5f6883683c91ad7e1af32b7ceeb604d68e2865
Author: Marcin Slusarz <marcin.slusarz@gmail.com>
Date: Fri Feb 8 04:20:12 2008 -0800
byteorder: move le32_add_cpu & friends from OCFS2 to core
moves le*_add_cpu and be*_add_cpu functions from OCFS2 to core
header and converted some existing code to it. We port
it here as later kernels will most likely use it.
Thanks to Bill Moss <bmoss@clemson.edu> for reporting this.
