On platforms where the Low Power S0 Idle _DSM interface is used, on wakeup from suspend-to-idle, when it is known that the ACPI SCI has triggered while suspended, dispatch the EC GPE in order to catch all EC events that may have triggered the wakeup before carrying out the noirq phase of device resume. That is needed to handle power button wakeup on some platforms where the EC goes into a low-power mode during suspend-to-idle and while in that mode it will discard events after a timeout. If that timeout is shorter than the time it takes to complete the noirq resume of devices, looking for EC events after the latter is too late. Signed-off-by: Rafael J.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
