Merge tag 'nommu-for-rmk' of git://git.pengutronix.de/git/ukl/linux into devel-stable

Two different fixes for the same problem making some ARM nommu configurations
not boot since 3.6-rc1. The problem is that user_addr_max returned the biggest
available RAM address which makes some copy_from_user variants fail to read
from XIP memory.

Even in the presence of one of the two fixes the other still makes sense, so
both patches are included here.

This problem was the last one preventing efm32 boot to a prompt with mainline.
