On Bay Trail / Cherry Trail systems with a LID switch, the LID switch is often connect to a gpioint handled by an _IAE event handler. Before this commit such systems would not wake up when opening the lid, requiring the powerbutton to be pressed after opening the lid to wakeup. Note that Bay Trail / Cherry Trail systems use suspend-to-idle, so the interrupts are generated anyway on those lines on lid switch changes, but they are treated by the IRQ subsystem as spurious while suspended if not marked as wakeup IRQs. This commit calls enable_irq_wake() for _IAE GpioInts with a valid event handler which have their Wake flag set. This fixes such systems not waking up when opening the lid.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
