mm, pcp: share common code between memory hotplug and percpu sysctl handler

Browse source

Both the percpu_pagelist_fraction sysctl handler and memory hotplug have
a common requirement of updating the pcpu page allocation batch and high
values.  Split the relevant helper to share common code.

No functional change.
