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.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "The big ticket items here are the rework of suspend-to-idle in order to add proper support for power button wakeup from it on recent Dell laptops and the rework of interfaces exporting the current CPU frequency on x86. In addition to that, support for a few new pieces of hardware is added, the PCI/ACPI device wakeup infrastructure is simplified significantly and the wakeup IRQ framework is fixed to unbreak the IRQ bus locking infrastructure. Also, there are some functional improvements for intel_pstate, tools updates and small fixes and cleanups all over. Specifics: - Rework suspend-to-idle to allow it to take wakeup events signaled by the EC into account on ACPI-based platforms in order to properly support power button wakeup from suspend-to-idle on recent Dell laptops (Rafael Wysocki). That includes the core suspend-to-idle code rework, support for the Low Power S0 _DSM interface, and support for the ACPI INT0002 Virtual GPIO device from Hans de Goede (required for USB keyboard wakeup from suspend-to-idle to work on some machines). - Stop trying to export the current CPU frequency via /proc/cpuinfo on x86 as that is inaccurate and confusing (Len Brown). - Rework the way in which the current CPU frequency is exported by the kernel (over the cpufreq sysfs interface) on x86 systems with the APERF and MPERF registers by always using values read from these registers, when available, to compute the current frequency regardless of which cpufreq driver is in use (Len Brown). - Rework the PCI/ACPI device wakeup infrastructure to remove the questionable and artificial distinction between "devices that can wake up the system from sleep states" and "devices that can generate wakeup signals in the working state" from it, which allows the code to be simplified quite a bit (Rafael Wysocki). - Fix the wakeup IRQ framework by making it use SRCU instead of RCU which doesn't allow sleeping in the read-side critical sections, but which in turn is expected to be allowed by the IRQ bus locking infrastructure (Thomas Gleixner). - Modify some computations in the intel_pstate driver to avoid rounding errors resulting from them (Srinivas Pandruvada). - Reduce the overhead of the intel_pstate driver in the HWP (hardware-managed P-states) mode and when the "performance" P-state selection algorithm is in use by making it avoid registering scheduler callbacks in those cases (Len Brown). - Rework the energy_performance_preference sysfs knob in intel_pstate by changing the values that correspond to different symbolic hint names used by it (Len Brown). - Make it possible to use more than one cpuidle driver at the same time on ARM (Daniel Lezcano). - Make it possible to prevent the cpuidle menu governor from using the 0 state by disabling it via sysfs (Nicholas Piggin). - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1 on AMD systems (Yazen Ghannam). - Make the CPPC cpufreq driver take the lowest nonlinear performance information into account (Prashanth Prakash). - Add support for hi3660 to the cpufreq-dt driver, fix the imx6q driver and clean up the sfi, exynos5440 and intel_pstate drivers (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila, Rafael Wysocki, Tao Wang). - Fix a few minor issues in the generic power domains (genpd) framework and clean it up somewhat (Krzysztof Kozlowski, Mikko Perttunen, Viresh Kumar). - Fix a couple of minor issues in the operating performance points (OPP) framework and clean it up somewhat (Viresh Kumar). - Fix a CONFIG dependency in the hibernation core and clean it up slightly (Balbir Singh, Arvind Yadav, BaoJun Luo). - Add rk3228 support to the rockchip-io adaptive voltage scaling (AVS) driver (David Wu). - Fix an incorrect bit shift operation in the RAPL power capping driver (Adam Lessnau). - Add support for the EPP field in the HWP (hardware managed P-states) control register, HWP.EPP, to the x86_energy_perf_policy tool and update msr-index.h with HWP.EPP values (Len Brown). - Fix some minor issues in the turbostat tool (Len Brown). - Add support for AMD family 0x17 CPUs to the cpupower tool and fix a minor issue in it (Sherry Hurwitz). - Assorted cleanups, mostly related to the constification of some data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof Kozlowski)" * tag 'pm-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (69 commits) cpufreq: Update scaling_cur_freq documentation cpufreq: intel_pstate: Clean up after performance governor changes PM: hibernate: constify attribute_group structures. cpuidle: menu: allow state 0 to be disabled intel_idle: Use more common logging style PM / Domains: Fix missing default_power_down_ok comment PM / Domains: Fix unsafe iteration over modified list of domains PM / Domains: Fix unsafe iteration over modified list of domain providers PM / Domains: Fix unsafe iteration over modified list of device links PM / Domains: Handle safely genpd_syscore_switch() call on non-genpd device PM / Domains: Call driver's noirq callbacks PM / core: Drop run_wake flag from struct dev_pm_info PCI / PM: Simplify device wakeup settings code PCI / PM: Drop pme_interrupt flag from struct pci_dev ACPI / PM: Consolidate device wakeup settings code ACPI / PM: Drop run_wake from struct acpi_device_wakeup_flags PM / QoS: constify *_attribute_group.
