SYNOPSIS

void add_active_range(unsigned int nid, unsigned long start_pfn, unsigned long end_pfn);

ARGUMENTS

nid

The node ID the range resides on

start_pfn

The start PFN of the available physical memory

end_pfn

The end PFN of the available physical memory

DESCRIPTION

These ranges are stored in an early_node_map[] and later used by free_area_init_nodes to calculate zone sizes and holes. If the range spans a memory hole, it is up to the architecture to ensure the memory is not freed by the bootmem allocator. If possible the range being registered will be merged with existing ranges.
