An update to the bogus permission checks will come later during the merge window as feedback was not complete before heading of for travel. - Switch the timerqueue code to use cached rbtrees and get rid of the homebrewn caching of the leftmost node. - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a single function - Implement the separation of hrtimers to be forced to expire in hard interrupt context even when PREEMPT_RT is enabled and mark the affected timers accordingly. - Implement a mechanism for hrtimers and the timer wheel to protect RT against priority inversion and live lock issues when a (hr)timer which should be canceled is currently executing the callback.

2019-09-17Merge branch 'x86-apic-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 apic updates from Thomas Gleixner: - Cleanup the apic IPI implementation by removing duplicated code and consolidating the functions into the APIC core. - Implement a safe variant of the IPI broadcast mode. Contrary to earlier attempts this uses the core tracking of which CPUs have been brought online at least once so that a broadcast does not end up in some dead end in BIOS/SMM code when the CPU is still waiting for init. Once all CPUs have been brought up once, IPI broadcasting is enabled. Before that regular one by one IPIs are issued. - Drop the paravirt CR8 related functions as they have no user anymore - Initialize the APIC TPR to block interrupt 16-31 as they are reserved for CPU exceptions and should never be raised by any well behaving device. - Emit a warning when vector space exhaustion breaks the admin set affinity of an interrupt. - Make sure to use the NMI fallback when shutdown via reboot vector IPI fails. The original code had conditions which prevent the code path to be reached. - Annotate various APIC config variables as RO after init. [ The ipi broadcase change came in earlier through the cpu hotplug branch, but I left the explanation in the commit message since it was shared between the two different branches - Linus ] * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (28 commits) x86/apic/vector: Warn when vector space exhaustion breaks affinity x86/apic: Annotate global config variables as "read-only after init" x86/apic/x2apic: Implement IPI shorthands support x86/apic/flat64: Remove the IPI shorthand decision logic x86/apic: Share common IPI helpers x86/apic: Remove the shorthand decision logic x86/smp: Enhance native_send_call_func_ipi() x86/smp: Move smp_function_call implementations into IPI code x86/apic: Provide and use helper for send_IPI_allbutself() x86/apic: Add static key to Control IPI shorthands x86/apic: Move no_ipi_broadcast() out of 32bit x86/apic: Add NMI_VECTOR wait to IPI shorthand x86/apic: Remove dest argument from __default_send_IPI_shortcut() x86/hotplug: Silence APIC and NMI when CPU is dead x86/cpu: Move arch_smt_update() to a neutral place x86/apic/uv: Make x2apic_extra_bits static x86/apic: Consolidate the apic local headers x86/apic: Move apic_flat_64 header into apic directory x86/apic: Move ipi header into apic directory x86/apic: Cleanup the include maze ...

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.

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.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "Although there isn't tonnes of code in terms of line count, there are a fair few headline features which I've noted both in the tag and also in the merge commits when I pulled everything together. 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. Summary: - 52-bit virtual addressing in the kernel - New ABI to allow tagged user pointers to be dereferenced by syscalls - Early RNG seeding by the bootloader - Improve robustness of SMP boot - Fix TLB invalidation in light of recent architectural clarifications - Support for i.MX8 DDR PMU - Remove direct LSE instruction patching in favour of static keys - Function error injection using kprobes - Support for the PPTT "thread" flag introduced by ACPI 6.3 - Move PSCI idle code into proper cpuidle driver - Relaxation of implicit I/O memory barriers - Build with RELR relocations when toolchain supports them - Numerous cleanups and non-critical fixes" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (114 commits) arm64: remove __iounmap arm64: atomics: Use K constraint when toolchain appears to support it arm64: atomics: Undefine internal macros after use arm64: lse: Make ARM64_LSE_ATOMICS depend on JUMP_LABEL arm64: asm: Kill 'asm/atomic_arch.h' arm64: lse: Remove unused 'alt_lse' assembly macro arm64: atomics: Remove atomic_ll_sc compilation unit arm64: avoid using hard-coded registers for LSE atomics arm64: atomics: avoid out-of-line ll/sc atomics arm64: Use correct ll/sc atomic constraints jump_label: Don't warn on __exit jump entries docs/perf: Add documentation for the i.MX8 DDR PMU perf/imx_ddr: Add support for AXI ID filtering arm64: kpti: ensure patched kernel text is fetched from PoU arm64: fix fixmap copy for 16K pages and 48-bit VA perf/smmuv3: Validate groups for global filtering perf/smmuv3: Validate group size arm64: Relax Documentation/arm64/tagged-pointers.rst arm64: kvm: Replace hardcoded '1' with SYS_PAR_EL1_F arm64: mm: Ignore spurious translation faults taken from the kernel ...

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.
