Merge tag 'acpi-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These mostly update the ACPICA code in the kernel to upstream revision 20170531 which covers all of the new material from ACPI 6.2, including new tables (WSMT, HMAT, PPTT), new subtables and definition changes for some existing tables (BGRT, HEST, SRAT, TPM2, PCCT), new resource descriptor macros for pin control, support for new predefined methods (_LSI, _LSR, _LSW, _HMA), fixes and cleanups. On top of that, an additional ACPICA change from Kees (which also is upstream already) switches all of the definitions of function pointer structures in ACPICA to use designated initializers so as to make the structure layout randomization GCC plugin work with it. The rest is a few fixes and cleanups in the EC driver, an xpower PMIC driver update, a new backlight blacklist entry, and update of the tables configfs interface and a messages formatting cleanup. Specifics: - Update the ACPICA code in the kernel to upstream revision revision 20170531 (which covers all of the new material from ACPI 6.2) including: * Support for the PinFunction(), PinConfig(), PinGroup(), PinGroupFunction(), and PinGroupConfig() resource descriptors (Mika Westerberg). * Support for new subtables in HEST and SRAT, new notify value for HEST, header support for TPM2 table changes, and BGRT Status field update (Bob Moore). * Support for new PCCT subtables (David Box). * Support for _LSI, _LSR, _LSW, and _HMA as predefined methods (Erik Schmauss). * Support for the new WSMT, HMAT, and PPTT tables (Lv Zheng). * New UUID values for Processor Properties (Bob Moore). * New notify values for memory attributes and graceful shutdown (Bob Moore). * Fix related to the PCAT_COMPAT MADT flag (Janosch Hildebrand). * Resource to AML conversion fix for resources containing GPIOs (Mika Westerberg). * Disassembler-related updates (Bob Moore, David Box, Erik Schmauss). * Assorted fixes and cleanups (Bob Moore, Erik Schmauss, Lv Zheng, Cao Jin). - Modify ACPICA to always use designated initializers for function pointer structures to make the structure layout randomization GCC plugin work with it (Kees Cook). - Update the tables configfs interface to unload SSDTs on configfs entry removal (Jan Kiszka). - Add support for the GPI1 regulator to the xpower PMIC Operation Region handler (Hans de Goede). - Fix ACPI EC issues related to conflicting EC definitions in the ECDT and in the ACPI namespace (Lv Zheng, Carlo Caione, Chris Chiu). - Fix an interrupt storm issue in the EC driver and make its debug output work with dynamic debug as expected (Lv Zheng). - Add ACPI backlight quirk for Dell Precision 7510 (Shih-Yuan Lee). - Fix whitespace in pr_fmt() to align log entries properly in some places in the ACPI subsystem (Vincent Legoll)" * tag 'acpi-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (63 commits) ACPI / EC: Add quirk for GL720VMK ACPI / EC: Fix media keys not working problem on some Asus laptops ACPI / EC: Add support to skip boot stage DSDT probe ACPI / EC: Enhance boot EC sanity check ACPI / video: Add quirks for the Dell Precision 7510 ACPI: EC: Fix EC command visibility for dynamic debug ACPI: EC: Fix an EC event IRQ storming issue ACPICA: Use designated initializers ACPICA: Update version to 20170531 ACPICA: Update a couple of debug output messages ACPICA: acpiexec: enhance local signal handler ACPICA: Simplify output for the ACPI Debug Object ACPICA: Unix application OSL: Correctly handle control-c (EINTR) ACPICA: Improvements for debug output only ACPICA: Disassembler: allow conflicting external declarations to be emitted. ACPICA: Disassembler: add external op to namespace on first pass ACPICA: Disassembler: prevent external op's from opening a new scope ACPICA: Changed Gbl_disasm_flag to acpi_gbl_disasm_flag ACPICA: Changing External to a named object ACPICA: Update two error messages to emit control method name ...
