The patch titled
Subject: crc32: fix mixing of endian-specific types
has been removed from the -mm tree. Its filename was
crc32-fix-mixing-of-endian-specific-types.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
From: Bob Pearson <rpearson@xxxxxxxxxxxxxxxxxxxxx>
Subject: crc32: fix mixing of endian-specific types
crc32.c in its original version freely mixed u32, __le32 and __be32 types
which caused warnings from sparse with __CHECK_ENDIAN__. This patch fixes
these by forcing the types to u32.
