Offsets 0x60 and 0x64 are used internally by kernel drivers that call the amd_smn_read() and amd_smn_write() functions. If userspace accesses the regions at the same time as the kernel it may cause malfunctions in drivers using the offsets. Add these offsets to the exclusions so that the kernel is tainted if a non locked down userspace tries to access them.

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 reStructuredText 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.
