mainlining shenanigans

Linus Torvalds 87dcebff92 The time and timers updates contain:
Core changes:
 
    - Allow runtime power management when the clocksource is changed.
 
    - A correctness fix for clock_adjtime32() so that the return value
      on success is not overwritten by the result of the copy to user.
 
    - Allow late installment of broadcast clockevent devices which was
      broken because nothing switched them over to oneshot mode. This went
      unnoticed so far because clockevent devices used to be built in, but
      now people started to make them modular.
 
    - Debugfs related simplifications
 
    - Small cleanups and improvements here and there
 
 Driver changes:
 
    - The usual set of device tree binding updates for a wide range
      of drivers/devices.
 
    - The usual updates and improvements for drivers all over the place but
      nothing outstanding.
 
    - No new clocksource/event drivers. They'll come back next time.

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.
