Linus Torvalds b34111a89f A set of updates for SMP function calls:
- Improve localitu of smp_call_function_any() by utilizing
     sched_numa_find_nth_cpu() instead of picking a random CPU
 
   - Wait for work completion in smp_call_function_many_cond() only when
     there was actually work enqueued
 
   - Simplify functions by unutlizing the appropriate cpumask_*()
     interfaces
 
   - Trivial cleanups

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 reStructuredText 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.
