名称	描述
mtrr_add_page	mtrr_add_page - Add a memory type region@base: Physical base address of region in pages (in units of 4 kB!)@size: Physical size of region in pages (4 kB)@type: Type of MTRR desired@increment: If this is true do usage counting on the region* Memory
mtrr_del_page	mtrr_del_page - delete a memory type region@reg: Register returned by mtrr_add@base: Physical base address@size: Size of region If register is supplied then base and size are ignored. This is* how drivers should call it.* Releases an MTRR region
reload_store
microcode_init
schedule_on_each_cpu	schedule_on_each_cpu - execute a function synchronously on each online CPU@func: the function to call schedule_on_each_cpu() executes @func on each online CPU using the* system workqueue and blocks until all CPUs have completed.
apply_wqattrs_lock
alloc_and_link_pwqs
smpboot_register_percpu_thread	smpboot_register_percpu_thread - Register a per_cpu thread related* to hotplug@plug_thread: Hotplug thread descriptor Creates and starts the threads on all online cpus.
smpboot_unregister_percpu_thread	smpboot_unregister_percpu_thread - Unregister a per_cpu thread related to hotplug@plug_thread: Hotplug thread descriptor Stops all threads on all possible cpus.
s2idle_enter
irq_build_affinity_masks	ld affinity in two stages:* 1) spread present CPU on these vectors* 2) spread other possible CPUs on these vectors
irq_calc_affinity_vectors	q_calc_affinity_vectors - Calculate the optimal number of vectors@minvec: The minimum number of vectors available@maxvec: The maximum number of vectors available*@affd: Description of the affinity requirements
rcu_barrier	_barrier - Wait until all in-flight call_rcu() callbacks complete
klp_try_complete_transition	Try to switch all remaining tasks to the target patch state by walking the* stacks of sleeping tasks and looking for any to-be-patched or* to-be-unpatched functions. If such functions are found, the task can't be* switched yet.
rebuild_sched_domains
cpuset_write_u64
cpuset_write_s64
cpuset_write_resmask	Common handling for a write to a "cpus" or "mems" file.
sched_partition_write
cpuset_css_online
cpuset_css_offline	If the cpuset being removed has its flag 'sched_load_balance'* enabled, then simulate turning sched_load_balance off, which* will call rebuild_sched_domains_locked(). That is not needed* in the default hierarchy where only changes in partition
ring_buffer_resize	g_buffer_resize - resize the ring buffer@buffer: the buffer to resize.@size: the new size.@cpu_id: the cpu buffer to resize Minimum size is 2 * BUF_PAGE_SIZE.* Returns 0 on success and < 0 on failure.
move_to_next_cpu
start_kthread	start_kthread - Kick off the hardware latency sampling/detector kthread* This starts the kernel thread that will sit and sample the CPU timestamp* counter (TSC or similar) and look for potential hardware latencies.
register_wide_hw_breakpoint	a set of per_cpu pointers to perf events
padata_set_cpumask	padata_set_cpumask: Sets specified by @cpumask_type cpumask to the value* equivalent to @cpumask
padata_alloc	padata_alloc - allocate and initialize a padata instance and specify* cpumasks for serial and parallel workers
padata_alloc_shell	padata_alloc_shell - Allocate and initialize padata shell.*@pinst: Parent padata_instance object.
torture_shuffle_tasks	Shuffle tasks such that we allow shuffle_idle_cpu to become idle.* A special case is when shuffle_idle_cpu = -1, in which case we allow* the tasks to run on all CPUs.
kmem_cache_create_usercopy	kmem_cache_create_usercopy - Create a cache with a region suitable* for copying to userspace@name: A string which is used in /proc/slabinfo to identify this cache.@size: The size of objects to be created in this cache.
kmem_cache_destroy	删除高速缓存区
kmem_cache_shrink	收缩缓存区
kmem_cache_shrink_all	kmem_cache_shrink_all - shrink a cache and all memcg caches for root cache*@s: The cache pointer
disable_swap_slots_cache_lock	Must not be called with cpu hot plug lock
