[PATCH 0/3 v2] lib/percpu_counter, cpu/hotplug: Cure the cpu_dying_mask woes

[Dennis Zhou]

Hi everyone,

This is a respin of Thomas' series [1] against v6.7-rc4. Largely it's
the same minus a slight change in percpu_counter.c for batch
percpu_counters and updating __percpu_counter_limited_add().

I don't think we reached an alternative resolution here so I can queue
this up and give it some soak time in for-next.

Thanks,
Dennis
