I just pushed a branch against rc7 with makefile fixes in place to fix
omap1 and omap2 only builds for this stuff. Inlined the delta here at
the end. Do you want me to repost the series as v14 for this or is the
attached delta ok for review purposes? All the changes have been
squashed to existing patches (except the 2 patches I posted separately
for DRA7xx / AM43xx only builds.)
The test branch itself can be found here:

Felipe, care to run your randconfig magic for this?
