[PATCH] sparsemem: provide pfn_to_nid
Before SPARSEMEM is initialised we cannot provide an efficient pfn_to_nid() implmentation; before initialisation is complete we use early_pfn_to_nid() to provide location information. Until recently there was no non-init user of this functionality. Provide a post init pfn_to_nid() implementation. Note that this implmentation assumes that the pfn passed has been validated with pfn_valid(). The current single user of this function already has this check.
