The pseries platform has been LPAR-only for several generations, and
the PAPR spec:
* Guarantees that timebase synchronization is performed by
the platform ("The timebase registers are synchronized by the
platform before CPUs are given to the OS" - 7.3.8 SMP Support).
* Completely omits the RTAS freeze-time-base and thaw-time-base RTAS
functions, which are CHRP artifacts.
This code is effectively unused on currently supported models, so drop
it.

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.
