Subject: Updated patches for journal checksums.

	The journal checksums patches for ext4 and e2fsprogs sent on 30th May
had run into problems on big-endian machines. I have made the required
The major updates are:
1. Checksum was written in little endian format in the commit header,
changed it to big-endian.
2. The crc32 code ported to userspace (which is used by e2fsprogs) had
problem with #ifdef, fixed that.
3. The crc32 user space code used i386 assembly code for swabbing
changed it to generic one.
4. Removed various #includes, which caused compilation errors on ppc

Any comments/suggestions are always welcome.
