Arnd found it for me.


They've done a perfect job of making the source available while making it
utterly dreadful to extract anything useful from.

 16084 files changed, 1322769 insertions(+), 285257 deletions(-)

It's full of gratuitous whitespace changes to files that definitely
aren't used (arch/alpha?  really?) and they've stripped out a lot of
comments that they didn't need to touch.

Forward porting a patch from 10 years ago wouldn't be easy, even if
they hadn't tried very hard to obfuscate their patch.  I don't think
this will be a fruitful line of inquiry.
