[JLSE-Intel-NDA] XPPSL Zonesort Module

The KNL systems now have the zonesort_module kernel module from XPPSL 1.4.1 loaded on boot, and permissions set on /sys/kernel/zone_sort_free_pages/nodeid to allow users to echo the memory numa node into it to trigger a sort. More details in the attached user guide in section 8. Note, I didn't apply this change to running systems, so you won't see the module loaded until the machine is rebooted. Ben
