git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "This includes some infrastructure changes in the PM core, mostly related to integration between runtime PM and system-wide suspend and hibernation, plus some driver changes depending on them and fixes for issues in that area which have become quite apparent recently. Also included are changes making more x86-based systems use the Low Power Sleep S0 _DSM interface by default, which turned out to be necessary to handle power button wakeups from suspend-to-idle on Surface Pro3. On the cpufreq front we have fixes and cleanups in the core, some new hardware support, driver updates and the removal of some unused code from the CPU cooling thermal driver. Apart from this, the Operating Performance Points (OPP) framework is prepared to be used with power domains in the future and there is a usual bunch of assorted fixes and cleanups. Specifics: - Define a PM driver flag allowing drivers to request that their devices be left in suspend after system-wide transitions to the working state if possible and add support for it to the PCI bus type and the ACPI PM domain (Rafael Wysocki). - Make the PM core carry out optimizations for devices with driver PM flags set in some cases and make a few drivers set those flags (Rafael Wysocki). - Fix and clean up wrapper routines allowing runtime PM device callbacks to be re-used for system-wide PM, change the generic power domains (genpd) framework to stop using those routines incorrectly and fix up a driver depending on that behavior of genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven). - Fix and clean up the PM core's device wakeup framework and re-factor system-wide PM core code related to device wakeup (Rafael Wysocki, Ulf Hansson, Brian Norris). - Make more x86-based systems use the Low Power Sleep S0 _DSM interface by default (to fix power button wakeup from suspend-to-idle on Surface Pro3) and add a kernel command line switch to tell it to ignore the system sleep blacklist in the ACPI core (Rafael Wysocki). - Fix a race condition related to cpufreq governor module removal and clean up the governor management code in the cpufreq core (Rafael Wysocki). - Drop the unused generic code related to the handling of the static power energy usage model in the CPU cooling thermal driver along with the corresponding documentation (Viresh Kumar). - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng). - Add a new operating point to the imx6ul and imx6q cpufreq drivers and switch the latter to using clk_bulk_get() (Anson Huang, Dong Aisheng). - Add support for multiple regulators to the TI cpufreq driver along with a new DT binding related to that and clean up that driver somewhat (Dave Gerlach). - Fix a powernv cpufreq driver regression leading to incorrect CPU frequency reporting, fix that driver to deal with non-continguous P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat). - Add support for frequency scaling on Armada 37xx SoCs through the generic DT cpufreq driver (Gregory CLEMENT). - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT). - Fix a transition delay setting regression in the longhaul cpufreq driver (Viresh Kumar). - Add Skylake X (server) support to the intel_pstate cpufreq driver and clean up that driver somewhat (Srinivas Pandruvada). - Clean up the cpufreq statistics collection code (Viresh Kumar). - Drop cluster terminology and dependency on physical_package_id from the PSCI driver and drop dependency on arm_big_little from the SCPI cpufreq driver (Sudeep Holla). - Add support for system-wide suspend and resume to the RAPL power capping driver and drop a redundant semicolon from it (Zhen Han, Luis de Bethencourt). - Make SPI domain validation (in the SCSI SPI transport driver) and system-wide suspend mutually exclusive as they rely on the same underlying mechanism and cannot be carried out at the same time (Bart Van Assche). - Fix the computation of the amount of memory to preallocate in the hibernation core and clean up one function in there (Rainer Fiebig, Kyungsik Lee). - Prepare the Operating Performance Points (OPP) framework for being used with power domains and clean up one function in it (Viresh Kumar, Wei Yongjun). - Clean up the generic sysfs interface for device PM (Andy Shevchenko). - Fix several minor issues in power management frameworks and clean them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven, Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker, Sergey Senozhatsky, gaurav jindal). - Make it easier to disable PM via Kconfig (Mark Brown). - Clean up the cpupower and intel_pstate_tracer utilities (Doug Smythies, Laura Abbott)" * tag 'pm-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (89 commits) PCI / PM: Remove spurious semicolon cpufreq: scpi: remove arm_big_little dependency drivers: psci: remove cluster terminology and dependency on physical_package_id powercap: intel_rapl: Fix trailing semicolon dmaengine: rcar-dmac: Make DMAC reinit during system resume explicit PM / runtime: Allow no callbacks in pm_runtime_force_suspend|resume() PM / hibernate: Drop unused parameter of enough_swap PM / runtime: Check ignore_children in pm_runtime_need_not_resume() PM / runtime: Rework pm_runtime_force_suspend/resume() PM / genpd: Stop/start devices without pm_runtime_force_suspend/resume() cpufreq: powernv: Dont assume distinct pstate values for nominal and pmin cpufreq: intel_pstate: Add Skylake servers support cpufreq: intel_pstate: Replace bxt_funcs with core_funcs platform/x86: surfacepro3: Support for wakeup from suspend-to-idle ACPI / PM: Use Low Power S0 Idle on more systems PM / wakeup: Print warn if device gets enabled as wakeup source during sleep PM / domains: Don't skip driver's ->suspend|resume_noirq() callbacks PM / core: Propagate wakeup_path status flag in __device_suspend_late() PM / core: Re-structure code for clearing the direct_complete flag powercap: add suspend and resume mechanism for SOC power limit ...

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull init_task initializer cleanups from David Howells: "It doesn't seem useful to have the init_task in a header file rather than in a normal source file. We could consolidate init_task handling instead and expand out various macros. Here's a series of patches that consolidate init_task handling: (1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and openrisc. (2) Alter the INIT_TASK_DATA linker script macro to set init_thread_union and init_stack rather than defining these in C. Insert init_task and init_thread_into into the init_stack area in the linker script as appropriate to the configuration, with different section markers so that they end up correctly ordered. We can then get merge ia64's init_task.c into the main one. We then have a bunch of single-use INIT_*() macros that seem only to be macros because they used to be used per-arch. We can then expand these in place of the user and get rid of a few lines and a lot of backslashes. (3) Expand INIT_TASK() in place. (4) Expand in place various small INIT_*() macros that are defined conditionally. Expand them and surround them by #if[n]def/#endif in the .c file as it takes fewer lines. (5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place. (6) Expand INIT_STRUCT_PID in place.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Arnd Bergmann: "We have various small DT fixes, and one important regression fix: The recent device tree bugfixes that were intended to address issues that 'dtc' started warning about in 4.15 fixed various USB PHY device nodes, but it turns out that we had code that depended on those nodes being incorrect and the probe failing with a particular error code. With the workaround we can also deal with correct device nodes. The DT fixes include: - Allwinner A10 and A20 had the display pipeline set up incorrectly (introduced in v4.15) - The Altera PMU lacked an interrupt-parent (never worked) - Pin muxing on the Openblocks A7 (never worked) - Clocks might get set up wrong on Armada 7K/8K (4.15 regression) We now have additional device tree patches to address all the remaining warnings introduced in 4.15, but decided to queue them for 4.16 instead, to avoid risking another regression like the USB PHY thing mentioned above. * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: phy: work around 'phys' references to usb-nop-xceiv devices ARM: sunxi_defconfig: Enable CMA arm64: dts: socfpga: add missing interrupt-parent ARM: dts: sun[47]i: Fix display backend 1 output to TCON0 remote endpoint ARM64: dts: marvell: armada-cp110: Fix clock resources for various node ARM: dts: da850-lcdk: Remove leading 0x and 0s from unit address ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7
2018-01-19ARM: sunxi_defconfig: Enable CMAMaxime Ripard1-0/+2
The DRM driver most notably, but also out of tree drivers (for now) like the VPU or GPU drivers, are quite big consumers of large, contiguous memory buffers. However, the sunxi_defconfig doesn't enable CMA in order to mitigate that, which makes them almost unusable. Enable it to make sure it somewhat works.

2018-01-17ARM: net: bpf: clarify tail_call indexRussell King1-1/+1

2018-01-17ARM: net: bpf: fix LDX instructionsRussell King1-28/+33
When the source and destination register are identical, our JIT does not generate correct code, which leads to kernel oopses.

2018-01-17ARM: net: bpf: fix register savingRussell King1-58/+22
When an eBPF program tail-calls another eBPF program, it enters it after the prologue to avoid having complex stack manipulations. This can lead to kernel oopses, and similar. Resolve this by always using a fixed stack layout, a CPU register frame pointer, and using this when reloading registers before returning.

2018-01-17ARM: net: bpf: correct stack layout documentationRussell King1-8/+27

As per 2dede2d8e925 ("ARM EABI: stack pointer must be 64-bit aligned after a CPU exception") the stack should be aligned to a 64-bit boundary on EABI systems. Ensure that the eBPF JIT appropraitely aligns the stack. Fixes: 39c13c204bb1 ("arm: eBPF JIT compiler") Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-01-17ARM: net: bpf: fix tail call jumpsRussell King1-1/+1
When a tail call fails, it is documented that the tail call should continue execution at the following instruction. An example tail call sequence is: 12: (85) call bpf_tail_call#12 13: (b7) r0 = 0 14: (95) exit The ARM assembler for the tail call in this case ends up branching to instruction 14 instead of instruction 13, resulting in the BPF filter returning a non-zero value: 178: ldr r8, [sp, #588] ; insn 12 17c: ldr r6, [r8, r6] 180: ldr r8, [sp, #580] 184: cmp r8, r6 188: bcs 0x1e8 18c: ldr r6, [sp, #524] 190: ldr r7, [sp, #528] 194: cmp r7, #0 198: cmpeq r6, #32 19c: bhi 0x1e8 1a0: adds r6, r6, #1 1a4: adc r7, r7, #0 1a8: str r6, [sp, #524] 1ac: str r7, [sp, #528] 1b0: mov r6, #104 1b4: ldr r8, [sp, #588] 1b8: add r6, r8, r6 1bc: ldr r8, [sp, #580] 1c0: lsl r7, r8, #2 1c4: ldr r6, [r6, r7] 1c8: cmp r6, #0 1cc: beq 0x1e8 1d0: mov r8, #32 1d4: ldr r6, [r6, r8] 1d8: add r6, r6, #44 1dc: bx r6 1e0: mov r0, #0 ; insn 13 1e4: mov r1, #0 1e8: add sp, sp, #596 ; insn 14 1ec: pop {r4, r5, r6, r7, r8, sl, pc} For other sequences, the tail call could end up branching midway through the following BPF instructions, or maybe off the end of the function, leading to unknown behaviours.

Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C For simplicity, two sed expressions were used to solve each warnings separately. To make the regex expression more robust a few other issues were resolved, namely setting unit-address to lower case, and adding a whitespace before the the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions This will solve as a side effect warning: Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>" This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation") Reported-by: David Daney <ddaney@caviumnetworks.com> Suggested-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
2018-01-05ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7Thomas Petazzoni1-2/+8
MPP7 is currently muxed as "gpio", but this function doesn't exist for MPP7, only "gpo" is available. This causes the following error: kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7 pinctrl core: failed to register map default (6): invalid type given kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22 kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22 kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22 So the pinctrl driver is not probed, all device drivers (including the UART driver) do a -EPROBE_DEFER, and therefore the system doesn't really boot (well, it boots, but with no UART, and no devices that require pin-muxing). Back when the Device Tree file for this board was introduced, the definition was already wrong. The pinctrl driver also always described as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11, a hog pin failing to be muxed was turned from a simple warning to a hard error that caused the entire pinctrl driver probe to bail out. This is probably the result of commit 6118714275f0a ("pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()"). This commit fixes the Device Tree to use the proper "gpo" function for MPP7, which fixes the boot of OpenBlocks A7, which was broken since Linux 4.11.

The EMAC bindings were developed for 4.13, but reverted at the last minute. They were finalized and brought back for 4.15. However in the time between, regulator support for the A64 boards was merged. When EMAC device tree changes were reintroduced, this was not taken into account. Second, a patch that adds OF based modalias uevent for RSB slave devices. This has been missing since the introduction of RSB, and recently with PMIC regulator support introduced for the A64, has been seen affecting distributions, which have the all-important PMIC mfd drivers built as modules, which then don't get loaded. Other minor cleanups include final conversion of raw indices to CCU binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero Plus2, and adding a missing compatible for the PMIC on the TBS A711 tablet. * tag 'sunxi-fixes-for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: ARM: dts: sun8i: a711: Reinstate the PMIC compatible arm64: dts: orange-pi-zero-plus2: fix sdcard detect arm64: allwinner: a64-sopine: Fix to use dcdc1 regulator instead of vcc3v3 ARM: dts: sunxi: Convert to CCU index macros for HDMI controller sunxi-rsb: Include OF based modalias in device uevent arm64: allwinner: a64: add Ethernet PHY regulator for several boards
