/*
* Nodemasks provide a bitmap suitable for representing the
* set of Node's in a system, one bit position per Node number.
*
* See detailed comments in the file linux/bitmap.h describing the
* data type on which these nodemasks are based.
*
* For details of nodemask_parse_user(), see bitmap_parse_user() in
* lib/bitmap.c. For details of nodelist_parse(), see bitmap_parselist(),
* also in bitmap.c. For details of node_remap(), see bitmap_bitremap in
* lib/bitmap.c. For details of nodes_remap(), see bitmap_remap in
* lib/bitmap.c. For details of nodes_onto(), see bitmap_onto in
* lib/bitmap.c. For details of nodes_fold(), see bitmap_fold in
* lib/bitmap.c.
*
* The available nodemask operations are:
*
* void node_set(node, mask) turn on bit 'node' in mask
* void node_clear(node, mask) turn off bit 'node' in mask
* void nodes_setall(mask) set all bits
* void nodes_clear(mask) clear all bits
* int node_isset(node, mask) true iff bit 'node' set in mask
* int node_test_and_set(node, mask) test and set bit 'node' in mask
*
* void nodes_and(dst, src1, src2) dst = src1 & src2 [intersection]
* void nodes_or(dst, src1, src2) dst = src1 | src2 [union]
* void nodes_xor(dst, src1, src2) dst = src1 ^ src2
* void nodes_andnot(dst, src1, src2) dst = src1 & ~src2
* void nodes_complement(dst, src) dst = ~src
*
* int nodes_equal(mask1, mask2) Does mask1 == mask2?
* int nodes_intersects(mask1, mask2) Do mask1 and mask2 intersect?
* int nodes_subset(mask1, mask2) Is mask1 a subset of mask2?
* int nodes_empty(mask) Is mask empty (no bits sets)?
* int nodes_full(mask) Is mask full (all bits sets)?
* int nodes_weight(mask) Hamming weight - number of set bits
*
* void nodes_shift_right(dst, src, n) Shift right
* void nodes_shift_left(dst, src, n) Shift left
*
* unsigned int first_node(mask) Number lowest set bit, or MAX_NUMNODES
* unsigend int next_node(node, mask) Next node past 'node', or MAX_NUMNODES
* unsigned int next_node_in(node, mask) Next node past 'node', or wrap to first,
* or MAX_NUMNODES
* unsigned int first_unset_node(mask) First node not set in mask, or
* MAX_NUMNODES
*
* nodemask_t nodemask_of_node(node) Return nodemask with bit 'node' set
* NODE_MASK_ALL Initializer - all bits set
* NODE_MASK_NONE Initializer - no bits set
* unsigned long *nodes_addr(mask) Array of unsigned long's in mask
*
* int
