In c0_compare_int_usable we clear compare interrupt by write value just read out from counter to compare register. However sometimes if those all instructions are graduated together then it's possible that at the time compare register is written, the counter haven't progressed, thus the interrupt is triggered again. It also applies to QEMU that instructions is executed significantly faster then counter. Offset the value used to clear interrupt by one to prevent that happen.

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.
