Currently, when updating section permissions to mark areas RO

modprobe early will trigger a fork/exec). Ensure all mm structres
get updated with the new section information.

Russell, does this work for you?
Did this end up in the patch tracker? (I just sent a patch that'll
collide with this... I'm happy to do the fix up.)
I put this in the patch tracker this morning.

Thanks,
