    memblock: Kill early_node_map[] · 0ee332c1
    Tejun Heo authored
    Now all ARCH_POPULATES_NODE_MAP archs select HAVE_MEBLOCK_NODE_MAP -
    there's no user of early_node_map[] left.  Kill early_node_map[] and
    replace ARCH_POPULATES_NODE_MAP with HAVE_MEMBLOCK_NODE_MAP.  Also,
    relocate for_each_mem_pfn_range() and helper from mm.h to memblock.h
    as page_alloc.c would no longer host an alternative implementation.
    
    This change is ultimately one to one mapping and shouldn't cause any
    observable difference; however, after the recent changes, there are
    some functions which now would fit memblock.c better than page_alloc.c
    and dependency on HAVE_MEMBLOCK_NODE_MAP instead of HAVE_MEMBLOCK
    doesn't make much sense on some of them.  Further cleanups for
    functions inside HAVE_MEMBLOCK_NODE_MAP in mm.h would be nice.
    
    -v2: Fix compile bug introduced by mis-spelling
     CONFIG_HAVE_MEMBLOCK_NODE_MAP to CONFIG_MEMBLOCK_HAVE_NODE_MAP in
     mmzone.h.  Reported by Stephen Rothwell.
