Hi Jesper,

Thanks for the patch! I had done a slightly different approach, but
am merging your changes into my tree now. I already have separate
patches for each driver subsystem, so I'll keep my versions, having
already made sure that your changes were identical.

For Documentation/features and the Kconfig files that have lists
of architectures, I also have separate patches that do the changes
for all architectures, to avoid touching those files (up to) eight times
for one trivial change each. I could redo those, but since your patch
conflicts with David Howell's patch for mn10300, it's easier to keep
what I already have.

This leaves basically the removal of arch/cris along with the MAINTAINER
file update. I'm keeping the patch I did, but change the author and
changelog text to what you sent, with my Signed-off-by and a list
of my modifications) added below.

Hope that works for you.

     Arnd
