Yeah, I just stuck my usual license header on it and didn't think about
authorship. I'll fix that, once we figure out what the appropriate name
is.

But, as this code is clearly a trivial adaptation of the existing kernel
code, it should carry a GPLv2 license. I'm also not particular as to the
EXPORT restriction, I was just following the EXPORT advice given for the
other newly exposed kernel symbols we're using.
