 /*
  * Cpumasks provide a bitmap suitable for representing the
- * set of CPU's in a system, one bit position per CPU number.
- *
- * The new cpumask_ ops take a "struct cpumask *"; the old ones
- * use cpumask_t.
- *
- * See detailed comments in the file linux/bitmap.h describing the
- * data type on which these cpumasks are based.
- *
- * For details of cpumask_scnprintf() and cpumask_parse_user(),
- * see bitmap_scnprintf() and bitmap_parse_user() in lib/bitmap.c.
- * For details of cpulist_scnprintf() and cpulist_parse(), see
- * bitmap_scnlistprintf() and bitmap_parselist(), also in bitmap.c.
- * For details of cpu_remap(), see bitmap_bitremap in lib/bitmap.c
- * For details of cpus_remap(), see bitmap_remap in lib/bitmap.c.
- * For details of cpus_onto(), see bitmap_onto in lib/bitmap.c.
- * For details of cpus_fold(), see bitmap_fold in lib/bitmap.c.
- *
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- * Note: The alternate operations with the suffix "_nr" are used
- *       to limit the range of the loop to nr_cpu_ids instead of
- *       NR_CPUS when NR_CPUS > 64 for performance reasons.
- *       If NR_CPUS is <= 64 then most assembler bitmask
- *       operators execute faster with a constant range, so
- *       the operator will continue to use NR_CPUS.
- *
- *       Another consideration is that nr_cpu_ids is initialized
- *       to NR_CPUS and isn't lowered until the possible cpus are
- *       discovered (including any disabled cpus).  So early uses
- *       will span the entire range of NR_CPUS.
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- *
- * The obsolescent cpumask operations are:
- *
- * void cpu_set(cpu, mask)		turn on bit 'cpu' in mask
- * void cpu_clear(cpu, mask)		turn off bit 'cpu' in mask
- * void cpus_setall(mask)		set all bits
- * void cpus_clear(mask)		clear all bits
- * int cpu_isset(cpu, mask)		true iff bit 'cpu' set in mask
- * int cpu_test_and_set(cpu, mask)	test and set bit 'cpu' in mask
- *
- * void cpus_and(dst, src1, src2)	dst = src1 & src2  [intersection]
- * void cpus_or(dst, src1, src2)	dst = src1 | src2  [union]
- * void cpus_xor(dst, src1, src2)	dst = src1 ^ src2
- * void cpus_andnot(dst, src1, src2)	dst = src1 & ~src2
- * void cpus_complement(dst, src)	dst = ~src
- *
- * int cpus_equal(mask1, mask2)		Does mask1 == mask2?
- * int cpus_intersects(mask1, mask2)	Do mask1 and mask2 intersect?
- * int cpus_subset(mask1, mask2)	Is mask1 a subset of mask2?
- * int cpus_empty(mask)			Is mask empty (no bits sets)?
- * int cpus_full(mask)			Is mask full (all bits sets)?
- * int cpus_weight(mask)		Hamming weigh - number of set bits
- * int cpus_weight_nr(mask)		Same using nr_cpu_ids instead of NR_CPUS
- *
- * void cpus_shift_right(dst, src, n)	Shift right
- * void cpus_shift_left(dst, src, n)	Shift left
- *
- * int first_cpu(mask)			Number lowest set bit, or NR_CPUS
- * int next_cpu(cpu, mask)		Next cpu past 'cpu', or NR_CPUS
- * int next_cpu_nr(cpu, mask)		Next cpu past 'cpu', or nr_cpu_ids
- *
- * cpumask_t cpumask_of_cpu(cpu)	Return cpumask with bit 'cpu' set
- *					(can be used as an lvalue)
- * CPU_MASK_ALL				Initializer - all bits set
- * CPU_MASK_NONE			Initializer - no bits set
- * unsigned long *cpus_addr(mask)	Array of unsigned long's in mask
- *
- * CPUMASK_ALLOC kmalloc's a structure that is a composite of many cpumask_t
- * variables, and CPUMASK_PTR provides pointers to each field.
- *
- * The structure should be defined something like this:
- * struct my_cpumasks {
- *	cpumask_t mask1;
- *	cpumask_t mask2;
- * };
- *
- * Usage is then:
- *	CPUMASK_ALLOC(my_cpumasks);
- *	CPUMASK_PTR(mask1, my_cpumasks);
- *	CPUMASK_PTR(mask2, my_cpumasks);
- *
- *	--- DO NOT reference cpumask_t pointers until this check ---
- *	if (my_cpumasks == NULL)
- *		"kmalloc failed"...
- *
- * References are now pointers to the cpumask_t variables (*mask1, ...)
- *
- *if NR_CPUS > BITS_PER_LONG
- *   CPUMASK_ALLOC(m)			Declares and allocates struct m *m =
- *						kmalloc(sizeof(*m), GFP_KERNEL)
- *   CPUMASK_FREE(m)			Macro for kfree(m)
- *else
- *   CPUMASK_ALLOC(m)			Declares struct m _m, *m = &_m
- *   CPUMASK_FREE(m)			Nop
- *endif
- *   CPUMASK_PTR(v, m)			Declares cpumask_t *v = &(m->v)
- * ------------------------------------------------------------------------
- *
- * int cpumask_scnprintf(buf, len, mask) Format cpumask for printing
- * int cpumask_parse_user(ubuf, ulen, mask)	Parse ascii string as cpumask
- * int cpulist_scnprintf(buf, len, mask) Format cpumask as list for printing
- * int cpulist_parse(buf, map)		Parse ascii string as cpulist

- *
- * int num_online_cpus()		Number of online CPUs

- * for_each_possible_cpu(cpu)		for-loop cpu over cpu_possible_map
- * for_each_online_cpu(cpu)		for-loop cpu over cpu_online_map
- * for_each_present_cpu(cpu)		for-loop cpu over cpu_present_map
- *
- * Subtlety:
- * 1) The 'type-checked' form of cpu_isset() causes gcc (3.3.2, anyway)
- *    to generate slightly worse code.  Note for example the additional
- *    40 lines of assembly code compiling the "for each possible cpu"
- *    loops buried in the disk_stat_read() macros calls when compiling
- *    drivers/block/genhd.c (arch i386, CONFIG_SMP=y).  So use a simple
- *    one-line #define for cpu_isset(), instead of wrapping an inline
- *    inside a macro, the way we do the other calls.
+ * set of CPU's in a system, one bit position per CPU number.  In general,
+ * only nr_cpu_ids (<= NR_CPUS) bits are valid.

+ *	hardware mechanism allowing the device to request a change of its power
+ *	state, such as PCI PME) should be enabled for it.

+ * @runtime_resume: Put the device into the fully active state in response to a
+ *	wake-up event generated by hardware or at the request of software.  If
+ *	necessary, put the device into the full power state and restore its
+ *	registers, so that it is fully operational.
+ *
+ * @runtime_idle: Device appears to be inactive and it might be put into a low
+ *	power state if all of the necessary conditions are satisfied.  Check
+ *	these conditions and handle the device as appropriate, possibly queueing
+ *	a suspend request for it.  The return value is ignored by the PM core.
