Pull RCU updates from Ingo Molnar: "The biggest change in this cycle is the conclusion of the big 'simplify RCU to two primary flavors' consolidation work - i.e. there's a single RCU flavor for any kernel variant (PREEMPT and !PREEMPT): - Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a single flavor similar to RCU-sched in !PREEMPT kernels and into a single flavor similar to RCU-preempt (but also waiting on preempt-disabled sequences of code) in PREEMPT kernels. This branch also includes a refactoring of rcu_{nmi,irq}_{enter,exit}() from Byungchul Park. - Now that there is only one RCU flavor in any given running kernel, the many "rsp" pointers are no longer required, and this cleanup series removes them. - This branch carries out additional cleanups made possible by the RCU flavor consolidation, including inlining now-trivial functions, updating comments and definitions, and removing now-unneeded rcutorture scenarios. - Now that there is only one flavor of RCU in any running kernel, there is also only on rcu_data structure per CPU. This means that the rcu_dynticks structure can be merged into the rcu_data structure, a task taken on by this branch. This branch also contains a -rt-related fix from Mike Galbraith. There were also other updates: - Documentation updates, including some good-eye catches from Joel Fernandes. - SRCU updates, most notably changes enabling call_srcu() to be invoked very early in the boot sequence. - Torture-test updates, including some preliminary work towards making rcutorture better able to find problems that result in insufficient grace-period forward progress. - Initial changes to RCU to better promote forward progress of grace periods, including fixing a bug found by Marius Hillenbrand and David Woodhouse, with the fix suggested by Peter Zijlstra" * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (140 commits) srcu: Make early-boot call_srcu() reuse workqueue lists rcutorture: Test early boot call_srcu() srcu: Make call_srcu() available during very early boot rcu: Convert rcu_state.ofl_lock to raw_spinlock_t rcu: Remove obsolete ->dynticks_fqs and ->cond_resched_completed rcu: Switch ->dynticks to rcu_data structure, remove rcu_dynticks rcu: Switch dyntick nesting counters to rcu_data structure rcu: Switch urgent quiescent-state requests to rcu_data structure rcu: Switch lazy counts to rcu_data structure rcu: Switch last accelerate/advance to rcu_data structure rcu: Switch ->tick_nohz_enabled_snap to rcu_data structure rcu: Merge rcu_dynticks structure into rcu_data structure rcu: Remove unused rcu_dynticks_snap() from Tiny RCU rcu: Convert "1UL << x" to "BIT(x)" rcu: Avoid resched_cpu() when rescheduling the current CPU rcu: More aggressively enlist scheduler aid for nohz_full CPUs rcu: Compute jiffies_till_sched_qs from other kernel parameters rcu: Provide functions for determining if call_rcu() has been invoked rcu: Eliminate ->rcu_qs_ctr from the rcu_dynticks structure rcu: Motivate Tiny RCU forward progress ...

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver" * tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (116 commits) gpio: Clarify kerneldoc on gpiochip_set_chained_irqchip() gpio: Remove unused 'irqchip' argument to gpiochip_set_cascaded_irqchip() gpio: Drop parent irq assignment during cascade setup mmc: pwrseq_simple: Fix incorrect handling of GPIO bitmap gpio: fix SNPS_CREG kconfig dependency warning gpiolib: Initialize gdev field before is used gpio: fix kernel-doc after devres.c file rename gpio: fix doc string for devm_gpiochip_add_data() to not talk about irq_chip gpio: syscon: Fix possible NULL ptr usage gpiolib: Show correct direction from the beginning pinctrl: msm: Use init_valid_mask exported function gpiolib: Add init_valid_mask exported function GPIO: add single-register GPIO via CREG driver dt-bindings: Document the Synopsys GPIO via CREG bindings gpio: mockup: use device properties instead of platform_data gpio: Slightly more helpful debugfs gpio: omap: Remove set but not used variable 'dev' gpio: omap: drop omap_gpio_list Accept partial 'gpio-line-names' property. gpio: omap: get rid of the conditional PM runtime calls ...

The init of the pkey module currently fails if the pckmo instruction or the subfunctions are not available. However, customers may restrict their LPAR to switch off exactly these functions and work with secure key only. So it is a valid case to have the pkey module active and use it for secure key to protected key transfer only. This patch moves the pckmo subfunction check from the pkey module init function into the internal function where the pckmo instruction is called. So now only on invocation of the pckmo instruction the check for the required subfunction is done. If not available EOPNOTSUPP is returned to the caller. The check for having the pckmo instruction available is still done during module init. This instruction came in with MSA 3 together with the basic set of kmc instructions needed to work with protected keys.

We use the term "TAB" before defining it later in the document. Fix that up by defining it at the first location.

Code of Conduct Interpretation: Add document explaining how the Code of Conduct is to be interpreted The Contributor Covenant Code of Conduct is a general document meant to provide a set of rules for almost any open source community. Every open-source community is unique and the Linux kernel is no exception. Because of this, this document describes how we in the Linux kernel community will interpret it. We also do not expect this interpretation to be static over time, and will adjust it as needed. This document was created with the input and feedback of the TAB as well as many current kernel maintainers.
