Subject: [git pull] m68knommu changes for v4.8

Hi Linus,

Can you please pull the m68knommu git tree, for-linus branch.

This series is all about Nicolas flat format support for MMU systems.
Traditional m68k no-MMU flat format binaries can now be run on m68k MMU
enabled systems too. The series includes some nice cleanups of the
binfmt_flat code and converts it to using proper user space accessor
functions. With all this in place you can boot and run a complete no-MMU
flat format based user space on an MMU enabled system.

Sorry it is based on a random commit after rc7. There was a merge clash
on binfmt_flat.c after rc7. But it was merge clean from this point.

Regards
Greg
