394 * idtentry_enter - Handle state tracking on ordinary idtentries
395 * @regs: Pointer to pt_regs of interrupted context
396 *
397 * Invokes:
398 * - lockdep irqflag state tracking as low level ASM entry disabled
399 * interrupts.
400 *
401 * - Context tracking if the exception hit user mode.
402 *
403 * - The hardirq tracer to keep the state consistent as low level ASM
404 * entry disabled interrupts.
405 *
406 * As a precondition, this requires that the entry came from user mode,
407 * idle, or a kernel context in which RCU is watching.
408 *
409 * For kernel mode entries RCU handling is done conditional. If RCU is
410 * watching then the only RCU requirement is to check whether the tick has
411 * to be restarted. If RCU is not watching then rcu_irq_enter() has to be
412 * invoked on entry and rcu_irq_exit() on exit.
413 *
414 * Avoiding the rcu_irq_enter/exit() calls is an optimization but also
415 * solves the problem of kernel mode pagefaults which can schedule, which
416 * is not possible after invoking rcu_irq_enter() without undoing it.
417 *
418 * For user mode entries irq_enter_from_user_mode() must be invoked to
419 * establish the proper context for NOHZ_FULL. Otherwise scheduling on exit
420 * would not be possible.
421 *
422 * Returns: An opaque object that must be passed to idtentry_exit()
423 *
424 * The return value must be fed into the state argument of
425 * idtentry_exit().

439 * If this entry hit the idle task invoke rcu_irq_enter() whether

442 * Interupts can nest when the first interrupt invokes softirq
443 * processing on return which enables interrupts.
444 *
445 * Scheduler ticks in the idle task can mark quiescent state and
446 * terminate a grace period, if and only if the timer interrupt is
447 * not nested into another interrupt.
448 *
449 * Checking for __rcu_is_watching() here would prevent the nesting
450 * interrupt to invoke rcu_irq_enter(). If that nested interrupt is
451 * the tick then rcu_flavor_sched_clock_irq() would wrongfully
452 * assume that it is the first interupt and eventually claim
453 * quiescient state and end grace periods prematurely.
454 *
455 * Unconditionally invoke rcu_irq_enter() so RCU state stays
456 * consistent.
457 *
458 * TINY_RCU does not support EQS, so let the compiler eliminate
459 * this part when enabled.
