Date
We plan to change mm->cpu_vm_mask definition later. Thus, this patch convert
it into proper macro.

tile is one of last two cpu_vm_mask direct access users. I hope convert it
even if anyone refuse [path 3/3].

Chris, I couldn't get cross compiler for tile. thus I hope you check it carefully.
Thanks.
