These should be in a header file (please run your code through sparse).

Same for these.

The files that you've taken this code from are GPLv2, but you've thrown
a GPLv2+ header on a file that's merely a copy of the original code.
As some of the code you've moved to this new file is from Nicolas and
Vincent, you need to seek their approval to make this change of license
terms, or keep the original license terms.
