The patch titled
ia64 specific for Sizing zones and holes in an architecture independent
has been removed from the -mm tree. Its filename is
have-ia64-use-add_active_range-and-free_area_init_nodes-fix.patch
This patch was dropped because it was folded into have-ia64-use-add_active_range-and-free_area_init_nodes.patch

Subject: ia64 specific for Sizing zones and holes in an architecture independent
From: "Bob Picco" <bob.picco@xxxxxx>
Mel's latest V9 regressed slightly for ia64 FLATMEM+VIRTUAL_MEM_MAP. When
the largest hole is greater than LARGE_GAP, vmem_map is allocated before
free_area_init_nodes; resultant crash follows. Rather than complicate
alloc_node_mem_map just for this ia64 case, add an adjustment to
node_mem_map which is later negated by alloc_node_mem_map.
Previous to V9, the mem_map adjustment was done in the scope where
allocation is achieved in alloc_node_mem_map. The current code is more
appropriate but unfortunately caused an issue for ia64.
