Indeed I realized after applying that we are cluttering the mm stuff inside ARC.

So I don't see real net improvement with this patch/

Right this is mm specific option which is provided for by arch. And even a
redirector like ARCH_HAS_FORCE_MAX and moving this to generic mm won't cut it
since the option values are arch specific !
