[ Upstream commit bb3ab81bdbd53f88f26ffabc9fb15bd8466486ec ] The UV5 platform synchronizes the TSCs among all chassis, and will not proceed to OS boot without achieving synchronization. Previous UV platforms provided a register indicating successful synchronization. This is no longer available on UV5. On this platform TSC_ADJUST should not be reset by the kernel.

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.
