Subject: [PATCH -mm 6/6] m68knommu: convert little-endian bitops macros to static inline functions
Date: Thu, 27 Jan 2011 22:56:23 +0900	[thread overview]
Message-ID: <1296136583-13815-7-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1296136583-13815-1-git-send-email-akinobu.mita@gmail.com>

(This patch is intended to be folded into the patch in -mm:
m68knommu-introduce-little-endian-bitops.patch)

A few little-endian bitops on m68knommu are written as preprocessor
macros with the cast to "unsigned long *".
This means that even non-pointers will be accepted without an error, and
that is a Very Bad Thing.

This converts the little-endian bitops macros to static inline functions
with proper prototypes.
