The patch titled Subject: mm/page_ext.c: drop pfn_present() check when onlining has been removed from the -mm tree. Its filename was mm-page_extc-drop-pfn_present-check-when-onlining.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: David Hildenbrand <david@xxxxxxxxxx> Subject: mm/page_ext.c: drop pfn_present() check when onlining Since commit c5e79ef561b0 ("mm/memory_hotplug.c: don't allow to online/offline memory blocks with holes") we disallow to offline any memory with holes. As all boot memory is online and hotplugged memory cannot contain holes, we never online memory with holes. This present check can be dropped.
