PCT_TO_HWP does not take the actual range of pstates exported by HWP_CAPABILITIES in account, and is broken on most platforms. Remove the macro and set the min and max pstate for hwp by determining the range and adjusting by the min and max percent limits values. Signed-off-by:

In current code, max_perf_pct might be smaller than min_perf_pct by improper user input: $ grep . /sys/devices/system/cpu/intel_pstate/m*_perf_pct /sys/devices/system/cpu/intel_pstate/max_perf_pct:100 /sys/devices/system/cpu/intel_pstate/min_perf_pct:100 $ echo 80 > /sys/devices/system/cpu/intel_pstate/max_perf_pct $ grep . /sys/devices/system/cpu/intel_pstate/m*_perf_pct /sys/devices/system/cpu/intel_pstate/max_perf_pct:80 /sys/devices/system/cpu/intel_pstate/min_perf_pct:100 Fix this problem by 2 steps: 1. Normalize the user input to [min_policy, max_policy]. 2. Make sure max_perf_pct>=min_perf_pct, suggested by Seiichi Ikarashi. Signed-off-by:

Its better to use __func__ to print functions name instead of writing the name in the print statement. This also has the advantage that a change in function's name doesn't force us to change the print message as well. Reviewed-by:

If ARM_MT8173_CPUFREQ is configured, and THERMAL is configured as module, the following build error is seen for arm:allmodconfig and arm64:allmodconfig. drivers/built-in.o: In function `mtk_cpufreq_ready': :(.text+0x32a20c): undefined reference to `of_cpufreq_cooling_register' drivers/built-in.o: In function `mtk_cpufreq_exit': :(.text+0x32a420): undefined reference to `cpufreq_cooling_unregister' The fix is similar to CPUFREQ_DT, but more restrictive since ARM_MT8173_CPUFREQ can not be built as module.

Tolerance applies on both sides of the target voltage, i.e. both min and max sides. But while checking if a voltage is supported by the regulator or not, we haven't taken care of tolerance on the lower side. Fix that.

Pull power management and ACPI updates from Rafael Wysocki: "From the number of commits perspective, the biggest items are ACPICA and cpufreq changes with the latter taking the lead (over 50 commits). On the cpufreq front, there are many cleanups and minor fixes in the core and governors, driver updates etc. We also have a new cpufreq driver for Mediatek MT8173 chips. ACPICA mostly updates its debug infrastructure and adds a number of fixes and cleanups for a good measure. The Operating Performance Points (OPP) framework is updated with new DT bindings and support for them among other things. We have a few updates of the generic power domains framework and a reorganization of the ACPI device enumeration code and bus type operations. And a lot of fixes and cleanups all over. Included is one branch from the MFD tree as it contains some PM-related driver core and ACPI PM changes a few other commits are based on. Specifics: - ACPICA update to upstream revision 20150818 including method tracing extensions to allow more in-depth AML debugging in the kernel and a number of assorted fixes and cleanups (Bob Moore, Lv Zheng, Markus Elfring). - ACPI sysfs code updates and a documentation update related to AML method tracing (Lv Zheng). - ACPI EC driver fix related to serialized evaluations of _Qxx methods and ACPI tools updates allowing the EC userspace tool to be built from the kernel source (Lv Zheng). - ACPI processor driver updates preparing it for future introduction of CPPC support and ACPI PCC mailbox driver updates (Ashwin Chaugule). - ACPI interrupts enumeration fix for a regression related to the handling of IRQ attribute conflicts between MADT and the ACPI namespace (Jiang Liu). - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi Kasagar). - ACPI device registration code reorganization to separate the sysfs-related code and bus type operations from the rest (Rafael J Wysocki). - Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause, Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss). - ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan Xinhui, Rafael J Wysocki). - cpufreq core cleanups on top of the previous changes allowing it to preseve its sysfs directories over system suspend/resume (Viresh Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior). - cpufreq fixes and cleanups related to governors (Viresh Kumar). - cpufreq updates (core and the cpufreq-dt driver) related to the turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz). - New DT bindings for Operating Performance Points (OPP), support for them in the OPP framework and in the cpufreq-dt driver plus related OPP framework fixes and cleanups (Viresh Kumar). - cpufreq powernv driver updates (Shilpasri G Bhat). - New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen). - Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean). - intel_pstate driver updates including Skylake-S support, support for enabling HW P-states per CPU and an additional vendor bypass list entry (Kristen Carlson Accardi, Chen Yu, Ethan Zhao). - cpuidle core fixes related to the handling of coupled idle states (Xunlei Pang). - intel_idle driver updates including Skylake Client support and support for freeze-mode-specific idle states (Len Brown). - Driver core updates related to power management (Andy Shevchenko, Rafael J Wysocki). - Generic power domains framework fixes and cleanups (Jon Hunter, Geert Uytterhoeven, Rajendra Nayak, Ulf Hansson). - Device PM QoS framework update to allow the latency tolerance setting to be exposed to user space via sysfs (Mika Westerberg). - devfreq support for PPMUv2 in Exynos5433 and a fix for an incorrect exynos-ppmu DT binding (Chanwoo Choi, Javier Martinez Canillas). - System sleep support updates (Alan Stern, Len Brown, SungEun Kim). - rockchip-io AVS support updates (Heiko Stuebner). - PM core clocks support fixup (Colin Ian King). - Power capping RAPL driver update including support for Skylake H/S and Broadwell-H (Radivoje Jovanovic, Seiichi Ikarashi). - Generic device properties framework fixes related to the handling of static (driver-provided) property sets (Andy Shevchenko). - turbostat and cpupower updates (Len Brown, Shilpasri G Bhat, Shreyas B Prabhu)" * tag 'pm+acpi-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (180 commits) cpufreq: speedstep-lib: Use monotonic clock cpufreq: powernv: Increase the verbosity of OCC console messages cpufreq: sfi: use kmemdup rather than duplicating its implementation cpufreq: drop !cpufreq_driver check from cpufreq_parse_governor() cpufreq: rename cpufreq_real_policy as cpufreq_user_policy cpufreq: remove redundant 'policy' field from user_policy cpufreq: remove redundant 'governor' field from user_policy cpufreq: update user_policy.* on success cpufreq: use memcpy() to copy policy cpufreq: remove redundant CPUFREQ_INCOMPATIBLE notifier event cpufreq: mediatek: Add MT8173 cpufreq driver dt-bindings: mediatek: Add MT8173 CPU DVFS clock bindings PM / Domains: Fix typo in description of genpd_dev_pm_detach() PM / Domains: Remove unusable governor dummies PM / Domains: Make pm_genpd_init() available to modules PM / domains: Align column headers and data in pm_genpd_summary output powercap / RAPL: disable the 2nd power limit properly tools: cpupower: Fix error when running cpupower monitor PM / OPP: Drop unlikely before IS_ERR(_OR_NULL) PM / OPP: Fix static checker warning (broken 64bit big endian systems) ...

Pull user namespace updates from Eric Biederman: "This finishes up the changes to ensure proc and sysfs do not start implementing executable files, as the there are application today that are only secure because such files do not exist. It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that did not show the proper source for files bind mounted from /proc/<pid>/ns/*. It also straightens out the handling of clone flags related to user namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER) when files such as /proc/<pid>/environ are read while <pid> is calling unshare. This winds up fixing a minor bug in unshare flag handling that dates back to the first version of unshare in the kernel. Finally, this fixes a minor regression caused by the introduction of sysfs_create_mount_point, which broke someone's in house application, by restoring the size of /sys/fs/cgroup to 0 bytes. Apparently that application uses the directory size to determine if a tmpfs is mounted on /sys/fs/cgroup. The bind mount escape fixes are present in Al Viros for-next branch. and I expect them to come from there.

For those of you feeling less adventurous, added hardware support on platforms such as TI DM814x and Gumstix Overo platforms might be more of your liking. We've got something for everyone here! Ahem. Cough. So, anyway... This is the usual large batch of DT updates. Lots and lots of smaller changes, some of the larger ones to point out are: - Rockchip veyron (Chromebook) support, as well as several other new boards - DRM support on Atmel AT91SAM9N12EK - USB additions on some Allwinner platforms - Mediatek MT6580 support - Freescale i.MX6UL support - cleanups for Renesas shmobile platforms - lots of added devices on LPC18xx - lots of added devices and boards on UniPhier There's also some dependent code added here, in particular some branches that are primarily merged through the clock tree" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (389 commits) ARM: tegra: Add gpio-ranges property ARM: tegra: Fix AHB base address on Tegra20, Tegra30 and Tegra114 ARM: tegra: Add Tegra124 PMU support ARM: tegra: jetson-tk1: Add GK20A GPU DT node ARM: tegra: venice2: Add GK20A GPU DT node ARM: tegra: Add IOMMU node to GK20A ARM: tegra: Add CPU regulator to the Jetson TK1 device tree ARM: tegra: Add entries for cpufreq on Tegra124 ARM: tegra: Enable the DFLL on the Jetson TK1 ARM: tegra: Add the DFLL to Tegra124 device tree ARM: dts: zynq: Add devicetree entry for Xilinx Zynq reset controller.

Pull ARM SoC driver updates from Olof Johansson: "Some releases this branch is nearly empty, others we have more stuff. It tends to gather drivers that need SoC modification or dependencies such that they have to (also) go in through our tree. For this release, we have merged in part of the reset controller tree (with handshake that the parts we have merged in will remain stable), as well as dependencies on a few clock branches. In general, new items here are: - Qualcomm driver for SMM/SMD, which is how they communicate with the coprocessors on (some) of their platforms - memory controller work for ARM's PL172 memory controller - reset drivers for various platforms - PMU power domain support for Marvell platforms - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (49 commits) ARM: tegra: cpuidle: implement cpuidle_state.enter_freeze() ARM: tegra: Disable cpuidle if PSCI is available soc/tegra: pmc: Use existing pclk reference soc/tegra: pmc: Remove unnecessary return statement soc: tegra: Remove redundant $(CONFIG_ARCH_TEGRA) in Makefile memory: tegra: Add Tegra210 support memory: tegra: Add support for a variable-size client ID bitfield clk: shmobile: rz: Add CPG/MSTP Clock Domain support clk: shmobile: rcar-gen2: Add CPG/MSTP Clock Domain support clk: shmobile: r8a7779: Add CPG/MSTP Clock Domain support clk: shmobile: r8a7778: Add CPG/MSTP Clock Domain support clk: shmobile: Add CPG/MSTP Clock Domain support ARM: dove: create a proper PMU driver for power domains, PMU IRQs and resets reset: reset-zynq: Adding support for Xilinx Zynq reset controller. docs: dts: Added documentation for Xilinx Zynq Reset Controller bindings.

Pull ARM SoC cleanups from Olof Johansson: "A large cleanup branch this release, with a healthy 10k negative line delta. Most of this is removal of legacy (non-DT) support of shmobile platforms. There is also removal of two non-DT platforms on OMAP, and the plat-samsung directory is cleaned out by moving most of the previously shared-location-but-not-actually-shared files from there to the appropriate mach directories instead. There are other sets of changes in here as well: - Rob Herring removed use of set_irq_flags under all platforms and moved to genirq alternatives - a series of timer API conversions to set-state interface - ep93xx, nomadik and ux500 cleanups from Linus Walleij - __init annotation fixes from Nicolas Pitre + a bunch of other changes that all add up to a nice set of cleanups" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (108 commits) ARM/fb: ep93xx: switch framebuffer to use modedb only ARM: gemini: Setup timer3 as free running timer ARM: gemini: Use timer1 for clockevent ARM: gemini: Add missing register definitions for gemini timer ARM: ep93xx/timer: Migrate to new 'set-state' interface ARM: nomadik: push accelerometer down to boards ARM: nomadik: move l2x0 setup to device tree ARM: nomadik: selectively enable UART0 on boards ARM: nomadik: move hog code to use DT hogs ARM: shmobile: Fix mismerges ARM: ux500: simplify secondary CPU boot ARM: SAMSUNG: remove keypad-core header in plat-samsung ARM: SAMSUNG: local watchdog-reset header in mach-s3c64xx ARM: SAMSUNG: local onenand-core header in mach-s3c64xx ARM: SAMSUNG: local irq-uart header in mach-s3c64xx ARM: SAMSUNG: local backlight header in mach-s3c64xx ARM: SAMSUNG: local ata-core header in mach-s3c64xx ARM: SAMSUNG: local regs-usb-hsotg-phy header in mach-s3c64xx ARM: SAMSUNG: local spi-core header in mach-s3c24xx ARM: SAMSUNG: local nand-core header in mach-s3c24xx ...
