On some laptops enabling wakeup on the GPIO interrupts used for ACPI _AEI event handling causes spurious wakeups. This commit adds a new honor_wakeup option, defaulting to true (our current behavior), which can be used to disable wakeup on troublesome hardware to avoid these spurious wakeups. This is a workaround for an architectural problem with s2idle under Linux where we do not have any mechanism to immediately go back to sleep after wakeup events, other then for embedded-controller events using the standard ACPI EC interface, for details see: https://lore.kernel.org/linux-acpi/61450f9b-cbc6-0c09-8b3a-aff6bf9a0b3c@redhat.com/ One series of laptops which is not able to suspend without this workaround is the HP x2 10 Cherry Trail models, this commit adds a DMI based quirk which makes sets honor_wakeup to false on these models.

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.
