- Expose CLOCK_TAI to instrumentation to aid with TSN debugging.
- Ensure that the clockevent is stopped when there is no timer armed to
avoid pointless wakeups.
- Make the sched clock frequency handling and rounding consistent.
- Provide a better debugobject hint for delayed works. The timer callback
is always the same, which makes it difficult to identify the underlying
work. Use the work function as a hint instead.
- Move the timer specific sysctl code into the timer subsystem.
- The usual set of improvements and cleanups

Pull timer and timekeeping updates from Thomas Gleixner:

avoid pointless wakeups.
- Make the sched clock frequency handling and rounding consistent.
- Provide a better debugobject hint for delayed works. The timer

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.
