iTCO_vendor_support's option vendorsupport=2 is a gross hack. It claims to extend the existing iTCO_wdt driver, but in fact programs a watchdog on a completely different device (Super-I/O) without requesting its I/O ports and without checking the device ID. This is an utterly dangerous thing to do. It also turns out to be unnecessary, because as far as I can tell, the code in question is basically duplicating what the clean w83627hf_wdt driver is doing. My guess is that on these SuperMicro boards which sparkled the implementation of vendorsupport=2, the watchdog functionality of the Intel south bridge is not used, and the watchdog feature of some W83627HF-like Super-I/O chip is used instead. So we should point the users to the w83627hf_wdt driver.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
