    [PATCH] use page_to_pfn() instead of mem_map[] · 27254059
    Andrew Morton authored
    A patch from Martin Bligh which cleans up the open-coded uses of
    mem_map for ia32.  Basically it replaces
    
    mem_map + pagenr
    
    with
    
    pfn_to_page(pagenr)
    
    in lots of places.  Because mem_map[] doesn't work like that with
    discontigmem.
    
    It also fixes a bug in bad_range, that happens to work for contig mem
    systems, but is incorrect.  Tested both with and without discontigmem
    support.
