git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull CPU hotplug updates from Thomas Gleixner: "A small update for the SMP hotplug code code: - Track "booted once" CPUs in a cpumask so the x86 APIC code has an easy way to decide whether broadcast IPIs are safe to use or not. - Implement a cpumask_or_equal() helper for the IPI broadcast evaluation. The above two changes have been also pulled into the x86/apic branch for implementing the conditional IPI broadcast feature. - Cache the number of online CPUs instead of reevaluating it over and over. num_online_cpus() is an unreliable snapshot anyway except when it is used outside a cpu hotplug locked region. The cached access is not changing this, but it's definitely faster than calculating the bitmap wheight especially in hot paths" * 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: cpu/hotplug: Cache number of online CPUs cpumask: Implement cpumask_or_equal() smp/hotplug: Track booted once CPUs in a cpumask

Pull ARM DT updates from Arnd Bergmann: "This is another huge branch with close to 450 changessets related to devicetree files, roughly half of this for 32-bit and 64-bit respectively. There are lots of cleanups and additional hardware support for platforms we already support based on SoCs from Renesas, ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers. A total of 6 new SoCs and 37 new boards gets added this time, one more SoC will come in a follow-up branch. Most of the new boards are for 64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7. Going more into details for SoC platforms with new hardware support: - The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform, usually paired with an external 5G modem. So far we only support the Qualcomm SM8150 MTP reference platform, but no actual products. - For the slightly older Qualcomm platforms, support for several interesting products is getting added: Three laptops based on Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed" aka Wileyfox Swift). - Mediatek MT7629 is a new wireless network router chip, similar to the older MT7623. It gets added together with the reference board implementation. - Allwinner V3 is a repackaged version of the existing low-end V3s chip, and is used in the tiny Lichee Pi Zero plus, also added here. There is also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the eMMC variant of the Olimex A64-Olinuxino development board. - NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family, similar to the i.MX8M Mini. As usual, there is a large number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight Innovations i.MX7 RMU2 board. - In a different NXP product line, the Layerscape LS1046A "Freeway" reference board gets added. - Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their set-top-box line and smart speaker with newer CPU and GPU cores compared to their predecessors. Both are now also supported by the Khadas VIM3 development board series, and the dts files for that get reorganized a bit to better deal with all variants. Another board based on SM1 that gets added is the SEI Robotics SEI610. - There are a handful of new x86 and Power9 server boards using Aspeed BMC chips that are gaining support for running Linux on the BMC through the OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably these are still new machines using SoCs based on the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based AST2600 is still ramping up. - There are three new end-user products using 32-bit Rockchips SoCs: Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings(digital signage, PoS, ...). - One more single-board computer based on the popular 64-bit RK3399 is added: the Leez RK3399 P710" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (467 commits) arm64: dts: qcom: Add Lenovo Yoga C630 ARM: dts: aspeed-g5: Fixe gpio-ranges upper limit ARM; dts: aspeed: mihawk: File should not be executable ARM: dts: aspeed: swift: Change power supplies to version 2 ARM: dts: aspeed: vesnin: Add secondary SPI flash chip ARM: dts: aspeed: vesnin: Add wdt2 with alt-boot option ARM: dts: aspeed-g4: Add all flash chips ARM: dts: exynos: Enable GPU/Mali T604 on Arndale board ARM: dts: exynos: Enable GPU/Mali T604 on Chromebook Snow ARM: dts: exynos: Add GPU/Mali T604 node to Exynos5250 ARM: dts: exynos: Fix min/max buck4 for GPU on Arndale board ARM: dts: exynos: Mark LDO10 as always-on on Peach Pit/Pi Chromebooks ARM: dts: exynos: Remove not accurate secondary ADC compatible arm64: dts: rockchip: limit clock rate of MMC controllers for RK3328 arm64: dts: meson-sm1-sei610: add stdout-path property back arm64: dts: meson-sm1-sei610: enable DVFS arm64: dts: khadas-vim3: add support for the SM1 based VIM3L dt-bindings: arm: amlogic: add Amlogic SM1 based Khadas VIM3L bindings arm64: dts: khadas-vim3: move common nodes into meson-khadas-vim3.dtsi arm64: dts: meson: g12a: add reset to tdm formatters ...

Pull ARM SoC platform updates from Arnd Bergmann: "The main change this time around is a cleanup of some of the oldest platforms based on the XScale and ARM9 CPU cores, which are between 10 and 20 years old. The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel IOP33x/IOP13xx platforms are removed after we determined that nobody is using them any more. The TI Davinci and NXP LPC32xx platforms on the other hand are still in active use and are converted to the ARCH_MULTIPLATFORM build, meaning that we can compile a kernel that works on these along with most other ARMv5 platforms. Changes toward that goal are also merged for IOP32x, but additional work is needed to complete this. Patches for the remaining ARMv5 platforms have started but need more work and some testing. Support for the new ASpeed AST2600 gets added, this is based on the Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and ARMv6 chips in the same family. Other changes include a cleanup of the ST-Ericsson ux500 platform and the move of the TI Davinci platform to a new clocksource driver" [ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being buildable on other platforms through COMPILE_TEST, but that causes new warnings that I most definitely do not want to see during the merge window as that could hide other issues.

The part I'm most pleased with is that we had 35 contributors this time around, which feels like a big jump from the usual small group of core arm64 arch developers. Hopefully they all enjoyed it so much that they'll continue to contribute, but we'll see. It's probably worth highlighting that we've pulled in a branch from the risc-v folks which moves our CPU topology code out to where it can be shared with others.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of changes in the GPIO subsystem for the v5.4 kernel cycle. Core changes: - Support hierarchical GPIO irqchips. We now have three consumers that can use this: Intel IXP4xx, ThunderX and Qualcomm SPMI GPIO (in the pinctrl subsystem). The support code has been long in the making and hashed out so it should be easily adaptable for all hierarchical irqchip parents. The code only gets compiled in if hierarchical irqchip is used at the topmost irq controller at least, as the hierarchical irqchip requires strict hierarchy all the way up in the system. - Determine the need for a "valid_mask" for GPIO lines on the gpio_chip and conversely for the "valid_mask" for the GPIO interrupt chip interrupt lines by looking for a .init_valid_mask() callback in the main chip or GPIO interrupt chip respectively. Allocate it with bitmap_alloc(). - Isolate the device tree/open firmware GPIO description code out in its own file properly. - Isolate the ACPI GPIO description code out in its own file properly. - Drop a whole lot of #ifdef:s in the main includes: it does not hurt to keep the include items around, and we get quicker and clearer compile failures if the appropriate kernel symbols are not selected for drivers. New/deleted drivers: - New driver for Aspeed SGPIO. - The KS8695 driver is deleted as the platform gets deleted from arch/arm in this kernel cycle. - The Cirrus Logic Madera driver now supports CS47L92 and CS47L15. - The Freescale MPC8xxx now supports LS1028A and LS1088A. Driver improvements: - We pass the GPIO irqchip intialization by directly filling in the struct instead of using set-up functions (the new way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.

The qt project was nice enough to send a mail pointing out that they have a pr up to switch to the pidfd api (cf. [2]). Second, this tag contains an extension to the waitid() syscall to make it possible to wait on the current process group in a race free manner (even though the actual problem is very unlikely) by specifing 0 together with the P_PGID type.

2019-09-11gpio: Initialize the irqchip valid_mask with a callbackLinus Walleij1-4/+10
After changing the valid_mask for the struct gpio_chip to detect the need and presence of a valid mask with the presence of a .init_valid_mask() callback to fill it in, we augment the gpio_irq_chip to use the same logic. Switch all driver using the gpio_irq_chio valid_mask over to this new method. This makes sure the valid_mask for the gpio_irq_chip gets filled in when we add the gpio_chip, which makes it a little easier to switch over drivers using the old way of setting up gpio_irq_chip over to the new method of passing the gpio_irq_chip along with the gpio_chip.

2019-09-08include/linux/compiler.h: fix Oops for Clang-compiled kernelsNick Desaulniers1-4/+4
GCC unescapes escaped string section names while Clang does not. Because __section uses the `#` stringification operator for the section name, it doesn't need to be escaped. This fixes an Oops observed in distro's that use systemd and not net.core.bpf_jit_enable=1, when their kernels are compiled with Clang.

2019-09-07ipc: fix sparc64 ipc() wrapperArnd Bergmann1-0/+19
Matt bisected a sparc64 specific issue with semctl, shmctl and msgctl to a commit from my y2038 series in linux-5.1, as I missed the custom sys_ipc() wrapper that sparc64 uses in place of the generic version that I patched. The problem is that the sys_{sem,shm,msg}ctl() functions in the kernel now do not allow being called with the IPC_64 flag any more, resulting in a -EINVAL error when they don't recognize the command. Instead, the correct way to do this now is to call the internal ksys_old_{sem,shm,msg}ctl() functions to select the API version. As we generally move towards these functions anyway, change all of sparc_ipc() to consistently use those in place of the sys_*() versions, and move the required ksys_*() declarations into linux/syscalls.h The IS_ENABLED(CONFIG_SYSVIPC) check is required to avoid link errors when ipc is disabled.

2019-09-06ipc: fix semtimedop for generic 32-bit architecturesArnd Bergmann1-1/+1
As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1 broke when commit 00bf25d693e7 ("y2038: use time32 syscall names on 32-bit") changed all system calls on all architectures that take a 32-bit time_t to point to the _time32 implementation, but left out semtimedop in the asm-generic header. This affects all 32-bit architectures using asm-generic/unistd.h: h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky. The notable exception is riscv32, which has dropped support for the time32 system calls entirely.
