[PATCH 2/2] mm: vmemmap: arm64: add vmemmap_verify check for hot-add node case

From: Lin Feng
Date: Mon Apr 08 2013 - 06:01:30 EST

In hot add node(memory) case, vmemmap pages are always allocated from other
node, but the current logic just skip vmemmap_verify check.
So we should also issue "potential offnode page_structs" warning messages
if we are the case.
