/*
 * Based on include/linux/nodemask.h
 * IOLINKmasks provide a bitmap suitable for representing the
 * set of IOLINK's in a system, one bit position per IOLINK domain number.
 *
 * IOLINK can be represented by global domain number and as
 * pair: node and local link number on the node,
 * So main macroses and functions operate with domain number and
 * can have appropriate macroses to operate with pair of node and link #,
 * for axample:
 *	iolink_set(domain, ...)
 *	node_iolink_set(node, link, ...)
 *
 * IOLINK is common name of IO management and can be connected to IOHUB
 * (controller of peripheral interfaces) or RDMA (DMA with remoute systems)
 * So macroses have alternative to operate with IOLINKS as IOHUBs and RDMAs,
 * for example:
 *	iolink_set(...)
 *	iohub_set(...)
 *	rdma_set(...)
 *
 * See detailed comments in the file linux/bitmap.h describing the
 * data type on which these iolinkmasks are based.
 *
 * For details of iolinkmask_scnprintf() and iolinkmask_parse(),
 * see bitmap_scnprintf() and bitmap_parse() in lib/bitmap.c.
 * For details of iolinklist_scnprintf() and iolinklist_parse(), see
 * bitmap_scnlistprintf() and bitmap_parselist(), also in bitmap.c.
 *
 * The available iolinkmask operations are:
 *
 * void iolink_set(iolink, mask)	turn on bit 'iolink' in mask
 * void iolink_clear(iolink, mask)	turn off bit 'iolink' in mask
 * void iolinks_setall(mask)		set all bits
 * void iolinks_clear(mask)		clear all bits
 * int iolink_isset(iolink, mask)	true iff bit 'iolink' set in mask
 * int iolink_test_and_set(iolink, mask) test and set bit 'iolink' in mask
 *
 * void iolinks_and(dst, src1, src2)	dst = src1 & src2  [intersection]
 * void iolinks_or(dst, src1, src2)	dst = src1 | src2  [union]
 * void iolinks_xor(dst, src1, src2)	dst = src1 ^ src2
 * void iolinks_andnot(dst, src1, src2)	dst = src1 & ~src2
 * void iolinks_complement(dst, src)	dst = ~src
 *
 * int iolinks_equal(mask1, mask2)	Does mask1 == mask2?
 * int iolinks_intersects(mask1, mask2)	Do mask1 and mask2 intersect?
 * int iolinks_subset(mask1, mask2)	Is mask1 a subset of mask2?
 * int iolinks_empty(mask)		Is mask empty (no bits sets)?
 * int iolinks_full(mask)		Is mask full (all bits sets)?
 * int iolinks_weight(mask)		Hamming weight - number of set bits
 *
 * void iolinks_shift_right(dst, src, n) Shift right
 * void iolinks_shift_left(dst, src, n)	Shift left
 *
 * int first_iolink(mask)		Number lowest set bit, or MAX_NUMIOLINKS
 * int next_iolink(iolink, mask)	Next iolink past 'iolink', or MAX_NUMIOLINKS
 * int first_unset_iolink(mask)		First iolink not set in mask, or
 *					MAX_NUMIOLINKS.
 *
 * iolinkmask_t iolinkmask_of_iolink(iolink) Return iolinkmask with bit 'iolink' set
 * IOLINK_MASK_ALL			Initializer - all bits set
 * IOLINK_MASK_NONE			Initializer - no bits set
 * unsigned long *iolinks_addr(mask)	Array of unsigned long's in mask
 *
 * int iolinkmask_scnprintf(buf, len, mask) Format iolinkmask for printing
 * int iolinkmask_parse(ubuf, ulen, mask) Parse ascii string as iolinkmask
 * int iolinklist_scnprintf(buf, len, mask) Format iolinkmask as list for printing
 * int iolinklist_parse(buf, map)	Parse ascii string as iolinklist
 *
 * for_each_iolink_mask(iolink, mask)	for-loop iolink over mask
 *
 * int num_online_iolinks()		Number of online IOLINKs
 * int num_possible_iolinks()		Number of all possible IOLINKs
 *
 * int iolink_online(iolink)		Is some iolink domain online?
 * int iolink_possible(iolink)		Is some iolink domain possible?
 *
 * iolink_set_online(iolink)		set bit 'iolink' in iolink_online_map
 * iolink_set_offline(iolink)		clear bit 'iolink' in iolink_online_map
 *
 * for_each_iolink(iolink)		for-loop iolink over iolink_possible_map
 * for_each_online_iolink(iolink)	for-loop iolink over iolink_online_map
 *
 * Subtlety:
 * 1) The 'type-checked' form of iolink_isset() causes gcc (3.3.2, anyway)
 *    to generate slightly worse code.  So use a simple one-line #define
 *    for iolink_isset(), instead of wrapping an inline inside a macro, the
 *    way we do the other calls.
