I searched in Linus's tree on kernel.org after I couldn't find it in
mine. I can see the commit (306cfd630a4d121cf4e08b894d8b4c4cf106e57e)
referred to in both trees but it doesn't include any changes to the
maple stuff.

http://lkml.org/lkml/2008/6/15/121 - removes the references from
keyboard
http://lkml.org/lkml/2008/6/15/122 - removes the references from the
headers

I don't think there is anything wrong with my environment. But I am
happy to submit a new set of patches
