Merge branch 'ja-nommu-for-rmk-v2' of git://linux-arm.org/linux-ja into devel-stable

This includes the following series sent earlier to the list:
 - nommu-fixes
 - R7 Support
 - MPU support

I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I were
discussing today until we've reached a conclusion/that's had some more
review.

This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now that
you've merged that. I've included the fix for limiting MPU to CPU_V7.
