[PATCH] sched: topology: add input parameter for sched_domain_flags_f()

quoted

From: Wang Qing <redacted>

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.

It is not passing the mask back, sched_domain_flags_f() doesn't use cpumask
at all, it always return fixed values. sd_topology_level select different 
sd_flag() to config, it's too primitive.

If an architecture can describe its cache topology clearly in every level,
the sd only need sched_domain_flags_f(cpumask) to get its ShPR flag.

Thanks,
Wang
