Subject[PATCH 2/3] Zone reclaim V3: Remove debris from old zone reclaim
Remove debris of old zone reclaim

Removes the leftovers from prior attempts to implement Zone reclaim.

sys_set_zone_reclaim is not rechable in 2.6.14.

The reclaim_pages field in struct zone is only used by sys_set_zone_reclaim.
