The patch titled
Subject: mm: remove early_pfn_in_nid() and CONFIG_NODES_SPAN_OTHER_NODES
has been removed from the -mm tree. Its filename was
mm-remove-early_pfn_in_nid-and-config_nodes_span_other_nodes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: mm: remove early_pfn_in_nid() and CONFIG_NODES_SPAN_OTHER_NODES
The memmap_init() function was made to iterate over memblock regions and
as the result the early_pfn_in_nid() function became obsolete. Since
CONFIG_NODES_SPAN_OTHER_NODES is only used to pick a stub or a real
implementation of early_pfn_in_nid(), it is also not needed anymore.
Remove both early_pfn_in_nid() and the CONFIG_NODES_SPAN_OTHER_NODES.
