Subject: [PATCH 01/22] bitops: merge little and big endian definisions in asm-generic/bitops/le.h
Date: Fri, 15 Oct 2010 18:46:00 +0900 [thread overview]
Message-ID: <1287135981-17604-2-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1287135981-17604-1-git-send-email-akinobu.mita@gmail.com>
In order to make the forthcoming changes smaller, this merges
macro definisions in asm-generic/bitops/le.h for big endian and
little endian as much as possible.
This also removes unused BITOP_WORD macro.
