**调用者**
名称	描述
cpu_rmap_update	pu_rmap_update - update CPU rmap following a change of object affinity@rmap: CPU rmap to update@index: Index of object whose affinity changed*@affinity: New CPU affinity of object
mcheck_init_device
rdtgroup_cpus_write
set_cache_qos_cfg
reset_all_ctrls
rdtgroup_rmdir
update_domains
rdtgroup_pseudo_locked_in_hierarchy	dtgroup_pseudo_locked_in_hierarchy - Pseudo-locked region in cache hierarchy@d: RDT domain under test The setup of a pseudo-locked region affects all cache instances within* the hierarchy of the region
native_smp_prepare_cpus	Prepare for SMP bootup.@max_cpus: configured maximum number of CPUs, It is a legacy parameter for common interface support.
x2apic_prepare_cpu
workqueue_set_unbound_cpumask	workqueue_set_unbound_cpumask - Set the low-level unbound cpumask@cpumask: the cpumask to set The low-level workqueues cpumask is a global cpumask that limits* the affinity of all unbound workqueues. This function check the @cpumask
cpupri_init	pupri_init - initialize the cpupri structure@cp: The cpupri context Return: -ENOMEM on memory allocation failure.
cpudl_init	pudl_init - initialize the cpudl structure*@cp: the cpudl max-heap context
init_rootdomain
sched_init_domains	Set up scheduler domains and groups. For now this just excludes isolated* CPUs, but could be used to exclude other special cases in the future.

membarrier_private_expedited
sync_runqueues_membarrier_state
alloc_node_to_cpumask
irq_build_affinity_masks	ld affinity in two stages:* 1) spread present CPU on these vectors* 2) spread other possible CPUs on these vectors
tick_broadcast_init
on_each_cpu_cond_mask	_each_cpu_cond(): Call a function on each processor for which* the supplied function cond_func returns true, optionally waiting* for all the required CPUs to finish
alloc_cpumasks	alloc_cpumasks - allocate three cpumasks for cpuset@cs: the cpuset that have cpumasks to be allocated.@tmp: the tmpmasks structure pointer* Return: 0 if successful, -ENOMEM otherwise.* Only one of the two input arguments should be non-NULL.
cpuset_init	puset_init - initialize cpusets at system boot* Description: Initialize top_cpuset
__ring_buffer_alloc	__ring_buffer_alloc - allocate a new ring_buffer@size: the size in bytes per cpu that is needed.@flags: attributes to set for the ring buffer.* Currently the only flag that is available is the RB_FL_OVERWRITE* flag
__tracing_open
