Sorry, also missed that. Added the list back to the CC.

Yes, I got the impression the ARM kernel situation is a little
fragmented :{ Just to be clear, for Fedora we would have to make sure
the ac100 specific patches from the mavin24, chromeos and nvidia kernel
trees move towards the lkml/linus tree? Or can we pick up some of the
patches and add them to the fedora spec file first for testing?
BTW. Would you happen to have (git) URLs for these trees to make it
easier to see the diffs against mainline?
Thanks,
Mark
