- Add TPAUSE based delay which allows the CPU to enter an optimized power
state while waiting for the delay to pass. The delay is based on TSC
cycles.
- Add tsc_early_khz command line parameter to workaround the problem that
overclocked CPUs can report the wrong frequency via CPUID.16h which
causes the refined calibration to fail because the delta to the initial
frequency value is too big. With the parameter users can provide an
halfways accurate initial value.

Pull x86 timer updates from Thomas Gleixner:
"X86 timer specific updates:
- Add TPAUSE based delay which allows the CPU to enter an optimized
power state while waiting for the delay to pass. The delay is based
on TSC cycles.

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.
