rip out previous armeb old-stat abi compat code since arm linux opinion is that the old stat.h abi was for little endian only ... people should use this patch to fix their armeb kernels: http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=863/1

-/* OK, this is ugly, but not much we can do about it.
- *
- * The issue at hand is that the kernel introduced an ABI change between 
- * 2.4 and 2.6 for big endian machines on some architectures in stat64 with 
- * st_dev and st_rdev fields.   Older kernels used 'short' but newer kernels 
- * use a 'long'.  As if that wasn't fun enough, the location of st_blocks and 
- * its padding have swapped.  So, when applicable, we need to detect and shift 
- * bits around and hope for the best.  The kernel at least helps us out a bit 
- * because it will be sure to zero out all padding fields.
- *
- * Unimportant Note About Mis-detections:
- * - if user is running a 2.4 system with the old ABI and they stat a file on 
- *   a system which major 0 / minor 0.  We can ignore this though because the 
- *   kernel has major 0 reserved for non mountable devices (wh00t!)
- * - if user is running a 2.6 system with the new ABI and they stat a file on 
- *   a device whose st_dev fills up the lower 6 bytes into the upper 2 bytes 
- *   which overlap.  Again we should be able to safely ignore this because 
- *   that means it'd be a pretty big ass (read: uncommon) major/minor combo :).
