When there is a package thermal interrupt with PROCHOT log, it will be processed and cleared. It is possible that there is an active HFI event status, which is about to get processed or getting processed. While clearing PROCHOT log bit, it will also clear HFI status bit. This means that hardware is free to update HFI memory. When clearing a package thermal interrupt, some processors will generate a "general protection fault" when any of the read only bit is set to 1. The driver maintains a mask of all read-write bits which can be set. This mask doesn't include HFI status bit. This bit will also be cleared, as it will be assumed read-only bit. So, add HFI status bit 26 to the mask.

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.
