NAME
       sparse_memory_present_with_active_regions - Call memory_present for each active range

SYNOPSIS
       void sparse_memory_present_with_active_regions(int nid);

ARGUMENTS
       nid
	   The node to call memory_present for. If MAX_NUMNODES, all nodes will be used.

DESCRIPTION
       If an architecture guarantees that all ranges registered with add_active_ranges contain no holes and may be freed, this function may be
       used instead of calling memory_present manually.
