This isn't the case for invocations from tasklets, workqueues or the primary interrupt handler on PREEMPT_RT. Once this gets noticed a "local_irq_disable|safe()" is added. To avoid further confusion this series adds generic_handle_irq_safe() which can be used from any context and adds a few user.
v2…v4:
- Correct kernel doc for generic_handle_irq_safe() as per Wolfram Sang.
- Use "misc" instead of "mfd" for the hi6421-spmi-pmic driver.
v2…v1: https://lore.kernel.org/all/20220131123404.175438-1-bigeasy@linutronix.de/
- Redo kernel-doc for generic_handle_irq_safe() in #1.
- Use generic_handle_irq_safe() instead of generic_handle_irq() in the patch description where I accidently used the wrong one.

Please use the official cover-letter format (--cover-letter).
It would have been nice to at least find a diff stat here.

Do we really need to coordinate this series cross-subsystem?
Can we first apply the API, then have each of the subsystems adapted separately? Does the change-over all need to happen concurrently?
If the latter is the case, is this set bisectable?
