    arch, mm: filter disallowed nodes from arch specific show_mem functions · 7bf02ea2
    David Rientjes authored
    Architectures that implement their own show_mem() function did not pass
    the filter argument to show_free_areas() to appropriately avoid emitting
    the state of nodes that are disallowed in the current context.  This patch
    now passes the filter argument to show_free_areas() so those nodes are now
    avoided.
    
    This patch also removes the show_free_areas() wrapper around
    __show_free_areas() and converts existing callers to pass an empty filter.
    
    ia64 emits additional information for each node, so skip_free_areas_zone()
    must be made global to filter disallowed nodes and it is converted to use
    a nid argument rather than a zone for this use case.
