mm: numa: do not automatically migrate KSM pages
KSM pages can be shared between tasks that are not necessarily related to each other from a NUMA perspective. This patch causes those pages to be ignored by automatic NUMA balancing so they do not migrate and do not cause unrelated tasks to be grouped together.
