cpumask_local_spread	pumask_local_spread - select the i'th cpu with local numa cpu's first@i: index number@node: local numa_node* This function selects an online CPU according to a numa aware policy;* local cpus are returned first, followed by non-local ones, then it
mce_device_remove
get_domain_from_cpu
update_closid_rmid	Update the PGR_ASSOC MSR on all cpus in @cpu_mask,* Per task closids/rmids must have been set up before calling this function.
set_cache_qos_cfg
reset_all_ctrls
add_rmid_to_limbo
update_domains

wq_select_unbound_cpu	When queueing an unbound work item to a wq, prefer local CPU if allowed* by wq_unbound_cpumask. Otherwise, round robin among the allowed ones to* avoid perturbing sensitive tasks.

cpufreq_this_cpu_can_update	pufreq_this_cpu_can_update - Check if cpufreq policy can be updated.@policy: cpufreq policy to check. Return 'true' if:* - the local and remote CPUs share @policy,* - dvfs_possible_from_any_cpu is set in @policy and the local CPU is not going
housekeeping_test_cpu
irq_percpu_is_enabled	q_percpu_is_enabled - Check whether the per cpu irq is enabled@irq: Linux irq number to check for Must be called from a non migratable context. Returns the enable* state of a per cpu interrupt on the current cpu.
handle_percpu_devid_irq	handle_percpu_devid_irq - Per CPU local irq handler with per cpu dev ids@desc: the interrupt description structure for this irq Per CPU interrupts on SMP machines without locking requirements

ipi_get_hwirq	pi_get_hwirq - Get the hwirq associated with an IPI to a cpu@irq: linux irq number@cpu: the target cpu* When dealing with coprocessors IPI, we need to inform the coprocessor of* the hwirq it needs to use to receive and send IPIs.
ipi_send_verify
profile_tick
tick_check_percpu
tick_device_uses_broadcast	Check, if the device is disfunctional and a place holder, which* needs to be handled by the broadcast device.
tick_do_broadcast	Broadcast the event to the cpus, which are set in the mask (mangled).
tick_resume_check_broadcast	This is called from tick_resume_local() on a resuming CPU. That's* called from the core resume function, tick_unfreeze() and the magic XEN* resume hackery.* In none of these cases the broadcast device mode can change and the
smp_call_function_any	smp_call_function_any - Run a function on any of the given cpus@mask: The mask of cpus it can run on.@func: The function to run. This must be fast and non-blocking.*@info: An arbitrary pointer to pass to the function.
on_each_cpu_mask	_each_cpu_mask(): Run a function on processors specified by* cpumask, which may include the local processor.@mask: The set of cpus to run on (only runs on online subset).@func: The function to run. This must be fast and non-blocking.
on_each_cpu_mask	Note we still need to test the mask even for UP* because we actually can get an empty mask from* code that on SMP might call us without the local* CPU in the mask.
multi_cpu_stop	This is the cpu_stop function which stops the CPU.
ring_buffer_wait	g_buffer_wait - wait for input to the ring buffer@buffer: buffer to wait on@cpu: the cpu buffer to wait on@full: wait until a full page is available, if @cpu != RING_BUFFER_ALL_CPUS If @cpu == RING_BUFFER_ALL_CPUS then the task will wake up as soon
ring_buffer_poll_wait	g_buffer_poll_wait - poll on buffer input@buffer: buffer to wait on@cpu: the cpu buffer to wait on@filp: the file descriptor@poll_table: The poll descriptor* If @cpu == RING_BUFFER_ALL_CPUS then the task will wake up as soon
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.
ring_buffer_lock_reserve	g_buffer_lock_reserve - reserve a part of the buffer@buffer: the ring buffer to reserve from@length: the length of the data to reserve (excluding event header)* Returns a reserved event on the ring buffer to copy directly to

ring_buffer_record_disable_cpu	g_buffer_record_disable_cpu - stop all writes into the cpu_buffer@buffer: The ring buffer to stop writes to.@cpu: The CPU buffer to stop* This prevents all writes to the buffer. Any attempt to write* to the buffer after this will fail and return NULL.
ring_buffer_record_enable_cpu	g_buffer_record_enable_cpu - enable writes to the buffer@buffer: The ring buffer to enable writes@cpu: The CPU to enable.* Note, multiple disables will need the same number of enables* to truly enable the writing (much like preempt_disable).

trace_rb_cpu_prepare	We only allocate new buffers, never free them if the CPU goes down.* If we were to free the buffer, then the user would lose any trace that was in* the buffer.
