out_of_memory() wants the zonelist that was used during allocation,

This would even change how panic_on_oom behaves for page fault OOMs
(in a completely unpredictable way) if we get CONSTRAINED_CPUSET.

This change makes no sense to me.

Allocations during fault will be constrained by the cpuset's mems, if we 
are oom then why would we panic when panic_on_oom == 1?

Can you please address the concerns I raised?

And please describe user-visible changes in the changelog.
