From c4945b9ed472e8796e352f10df9dbc2841ba7b61 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 23 Mar 2011 16:41:47 -0700 Subject: [PATCH] asm-generic: rename generic little-endian bitops functions As a preparation for providing little-endian bitops for all architectures, This renames generic implementation of little-endian bitops.
