Patch to kernel to make long names work on big-endian systems with VFAT

Figured I'd send this to Ben and the LinuxPPC devel list, because I think
everyone will want to see this. I figured out the mods to make in the vfat
FS driver to reorder the (little-endian) wide-character data for the long
name entries so that big-endian systems (like PowerPC) can read and write
VFAT filesystems correctly - finally, no more filenames like
"????????????".
