That's confusing, I think I figured it out but "try this patch" which
links to a message that refers to another patch and some commandline
options and some config options and doesn't say what the goal is, is a
lot for me to parse since I don't actually understand what's going on
here.

I think I got it all:
https://bugzilla.kernel.org/attachment.cgi?id=25969
https://bugzilla.kernel.org/attachment.cgi?id=25970

Let me know (using small words if necessary) if I screwed something up.

Thanks,
