Ditto on ARM.  This level of breakage is simply not acceptable soo
close to a release, and needs the change reverting.

Note that on ARM, "allmodconfig" is really meaningless since it only
tests one configuration.  Ditto for the other all*config options.
kautobuild (or building a range of defconfigs) is the only real way
to check for breakage on ARM.
