David Hildenbrand dccacf8def mm/page_ext.c: drop pfn_present() check when onlining ...

Since commit c5e79ef561 ("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.
