Introduce a new function, rearm_wake_irq(), allowing a wakeup IRQ to be armed for systen wakeup detection again without running any action handlers associated with it after it has been armed for wakeup detection and triggered. That is useful for IRQs, like ACPI SCI, that may deliver wakeup as well as non-wakeup interrupts when armed for systen wakeup detection. In those cases, it may be possible to determine whether or not the delivered interrupt is a systen wakeup one without running the entire action handler (or handlers, if the IRQ is shared) for the IRQ, and if the interrupt turns out to be a non-wakeup one, the IRQ can be rearmed with the help of the new function.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
