Linus Torvalds f41377609a Two fixes for the SMP related functionality:
- Make the UP version of smp_call_function_single() match SMP semantics
    when called for a not available CPU.  Instead of emitting a warning and
    assuming that the function call target is CPU0, return a proper error
    code like the SMP version does.
 
  - Remove a superfluous check in smp_call_function_many_cond()

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.
