Linus Torvalds 590680d139 Scheduler fixes/updates:
- Deduplicate the average computations in the scheduler core and the fair
    class code.
 
  - Fix a raise between runtime distribution and assignement which can cause
    exceeding the quota by up to 70%.
 
  - Prevent negative results in the imbalanace calculation
 
  - Remove a stale warning in the workqueue code which can be triggered
    since the call site was moved out of preempt disabled code. It's a false
    positive.
 
  - Deduplicate the print macros for procfs
 
  - Add the ucmap values to the SCHED_DEBUG procfs output for completness

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.
