	Some GED interrupts could be pending by the time we are doing a reboot. Even though GED driver uses devm_request_irq() to register the interrupt handler, the handler is not being freed on time during a shutdown since the driver is missing a shutdown callback. If the ACPI handler is no longer available, this causes an interrupt storm and delays shutdown. 1. Don't use devm family of functions for IRQ registration/free 2. Keep track of the events since free_irq() requires the dev_id parameter passed into the request_irq() function. 3. Call free_irq() on both remove and shutdown explicitly.

2016-05-09	ACPI / GED: make evged.c explicitly non-modular	Paul Gortmaker
	The Makefile/Kconfig currently controlling compilation of this code is: Makefile:acpi-$(CONFIG_ACPI_REDUCED_HARDWARE_ONLY) += evged.o drivers/acpi/Kconfig:config ACPI_REDUCED_HARDWARE_ONLY drivers/acpi/Kconfig: bool "Hardware-reduced ACPI support only" if EXPERT ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the code there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. The file wasn't explicitly including the module.h file but it did already have init.h so, unlike similar changes, this one has no header changes at all. We also delete the MODULE_LICENSE tag since all that information is already contained at the top of the file in the comments.

2016-04-09	ACPI: implement Generic Event Device	Sinan Kaya
	Generic Event Device described in ACPI 6.1 allows platforms to handle platform interrupts in ACPI ASL statements. It borrows constructs like _EVT from GPIO events. All interrupts are listed in _CRS and the handler is written in _EVT method. Here is an example. Device (GED0) { Name (_HID, "ACPI0013") Name (_UID, 0) Name(_CRS, ResourceTemplate () { Interrupt(ResourceConsumer, Edge, ActiveHigh, Shared, , , ) {123} }) Method (_EVT, 1) { if (Lequal(123, Arg0)) { } } } Wake capability has not been implemented yet.
