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 ... |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
