[ Upstream commitef0e3b650f] Threshold Event Counter Multiplier (TECM) is part of Monitor Mode Control Register A (MMCRA). This field along with Threshold Event Counter Exponent (TECE) is used to get threshould counter value. In Power10, this is a 8bit field, so patch fixes the current code to modify the MMCRA[TECM] extraction macro to handle this change. ISA v3.1 says this is a 7 bit field but POWER10 it's actually 8 bits which will hopefully be fixed in ISA v3.1 update.

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.
