Pull RCU fixes from Ingo Molnar: "This fixes sporadic ACPI related hangs in synchronize_rcu() that were caused by the ACPI code mistakenly relying on an aspect of RCU that was neither promised to work nor reliable but which happened to work - until in v4.9 we changed the RCU implementation, which made the hangs more prominent. Since the mis-use of the RCU facility wasn't properly detected and prevented either, these fixes make the RCU side work reliably instead of working around the problem in the ACPI code. Hence the slightly larger diffstat that goes beyond the normal scope of RCU fixes in -rc kernels" * 'rcu-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: rcu: Narrow early boot window of illegal synchronous grace periods rcu: Remove cond_resched() from Tiny synchronize_sched()
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
