mm: only display online cpus of the numa node ...
When I execute numactl -H (which reads /sys/devices/system/node/nodeX/cpumap
and displays cpumask_of_node for each node), I get different result
on X86 and arm64. For each numa node, the former only displayed online
CPUs, and the latter displayed all possible CPUs. Unfortunately, both
Linux documentation and numactl manual have not described it clear.
I sent a mail to ask for help, and Michal Hocko replied that he
preferred to print online cpus because it doesn't really make much sense
to bind anything on offline nodes.
Will said:
"I suspect the vast majority (if not all) code that reads this file was
developed for x86, so having the same behaviour for arm64 sounds like
something we should do ASAP before people try to special case with
things like #ifdef __aarch64__. I'd rather have this in 4.14 if
possible."
