sched_domain_flags_f() are statically set now, but actually, we can get a
lot of necessary information based on the cpu_map. e.g. we can know whether
its cache is shared.

Allows custom extension without affecting current.

This all still makes absolutely no sense. The architecture builds these
masks, the architecture is in charge of which flags function is called
on which mask.

Passing the mask back in means it lost the plot somewhere and doens't
know wth it's doing anymore.
