The host Linux timer code arms the decrementer with the value 'decrementers_next_tb - current_tb' using set_dec(), which stores val - 1 on Book3S-64, which is not quite the same as what KVM does to re-arm the host decrementer when exiting the guest. This shouldn't be a significant change, but it makes the logic match and avoids this small extra change being brought into the next patch.

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.
