    [PATCH] sparsemem: provide pfn_to_nid · 161599ff
    Andy Whitcroft authored
    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.
