An interrupt that is disabled/masked but set for wakeup may still need to be able to wake up the system from sleep states like "suspend to RAM". To that effect, introduce the IRQCHIP_ENABLE_WAKEUP_ON_SUSPEND flag. If the irqchip have this flag set, the irq PM code will enable/unmask the irqs that are marked for wakeup, but that are in a disabled state. On resume, such irqs will be restored back to their disabled state.

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.
