Linus Torvalds a773abf72e Urgent RCU pull request for v5.17
This pull request fixes a math error added in 7a30871b6a ("rcu-tasks:
 Introduce ->percpu_enqueue_shift for dynamic queue selection') during the
 v5.17 merge window.  This commit works correctly only on systems with a
 power-of-two number of CPUs, which just so happens to be the kind that
 rcutorture always uses by default.
 
 This pull request fixes the math so that things also work on systems
 that don't happen to have a power-of-two number of CPUs.

Pull RCU fix from Paul McKenney:
 "This fixes a brown-paper-bag bug in RCU tasks that causes things like
  BPF and ftrace to fail miserably on systems with non-power-of-two
  numbers of CPUs.

  It fixes a math error added in 7a30871b6a ("rcu-tasks: Introduce
  ->percpu_enqueue_shift for dynamic queue selection') during the v5.17
  merge window. This commit works correctly only on systems with a
  power-of-two number of CPUs, which just so happens to be the kind that
  rcutorture always uses by default.

  This pull request fixes the math so that things also work on systems
  that don't happen to have a power-of-two number of CPUs"

README

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.

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.
