Pull ACPI updates from Rafael Wysocki: "These update the ACPICA code in the kernel to follow upstream revision 20180313 which includes fixes related to the so-called module-level AML (mostly "if" type of statements outside of any methods) that should improve the handling of systems that load alternative SSDTs depending on the current configuration, for example, and event handling fixes related to disabling and enabling GPEs on system startup and on suspend/resume. Moreover, the ACPICA license boilerplate is replaced with SPDX license IDs which alone reduces the number of lines of ACPICA code in the kernel quite a bit. Also added is a new driver for the generic ACPI Time and Alarm Device (TAD). At the moment it only handles the most basic capabilities of the TAD, however. In addition to that the ACPI battery driver is improved to handle battery thresholds on ThinkPads, among other things, some bugs are fixed, a new backlight quirk is added and some documentation is updated. Specifics: - Update the in-kernel ACPICA code to upstream revision 20180313 including: * Module-level AML code handling fixes and simplifications (Bob Moore, Erik Schmauss). * Fixes and cleanups related to messaging (Bob Moore). * Events handling fixes related to disabling and enabling GPEs (Erik Schmauss). * Introduction of SPDX license identifiers and removal of license boilerplate in multiple files (Erik Schmauss). * Assorted fixes and cleanups (Bob Moore, Erik Schmauss, Hans de Goede, Seunghun Han). - Add new basic driver for the ACPI Time and Alarm Device (Rafael Wysocki). - Modify the ACPI battery driver to support battery thresholds on Lenovo ThinkPads (Ognjen Galic, Colin Ian King). - Avoid reporting battery capacity over 100 in the ACPI battery driver in some cases (Laszlo Toth). - Make the kernel recognize an OEM _OSI string from Dell to avoid power management issues with NVidia GPUs in Dell platforms (Alex Hung). - Make the PCI IRQ management code handle missing _PRS cleanly (Alex Hung). - Fix uevent notifications related to device hotplut (Lee, Chun-Yi). - Prevent the ACPI PAD driver from leaking memory (Lenny Szubowicz). - Update the ACPI CPPC library code to include subspace IDs in the kernel messages logged by it (George Cherian). - Add backlight quirk for Samsung 670Z5E (Hans de Goede). - Add the NFIT and HMAT tables to the list of ACPI tables that can be overridden via initrd (Dan Williams). - Fix and clean up some ACPI documentation and Kconfig help language (Aishwarya Pant, Randy Dunlap). - Replace license boilerplate with an SPDX license ID in the ACPI PMIC operation region handling code (Rajmohan Mani)" * tag 'acpi-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (39 commits) ACPI: acpi_pad: Fix memory leak in power saving threads ACPI / video: Add quirk to force acpi-video backlight on Samsung 670Z5E ACPI: Add Time and Alarm Device (TAD) driver ACPI / scan: Send change uevent with offine environmental data ACPI / Kconfig: Update ACPI_PROCFS_POWER help text ACPI / OSI: Add OEM _OSI strings to disable NVidia RTD3 ACPICA: Update version to 20180313 ACPICA: Cleanup/simplify module-level code support ACPICA: Events: add a return on failure from acpi_hw_register_read ACPICA: adding SPDX headers ACPICA: Rename a global for clarity, no functional change ACPICA: macros: fix ACPI_ERROR_NAMESPACE macro ACPICA: Change a compile-time option to a runtime option ACPICA: Remove calling of _STA from acpi_get_object_info() ACPICA: AML Debug Object: Don't ignore output of zero-length strings ACPICA: Fix memory leak on unusual memory leak ACPICA: Events: Dispatch GPEs after enabling for the first time ACPICA: Events: Add parallel GPE handling support to fix potential redundant _Exx evaluations ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume ACPICA: acpi: acpica: fix acpi operand cache leak in nseval.c ...
