Endianness Questions

[nick]

Hey Guys,
I have a question about ordering of bits with the types for signed and unsigned in the kernel tree.
I am wondering if my list below is a good list of major areas of the kernel that need variable ordering
based to a certain endianness. If there are any more I am missing please let me known.
Cheers Nick
