[ Upstream commit2d46d4877b] Raw event code has couple of fields "unit" and "cache" in it, to capture the "unit" to monitor for a given pmcxsel and cache reload qualifier to program in MMCR1. isa207_get_constraint() refers "unit" field to update the MMCRC (L2/L3) Event bus control fields with "cache" bits of the raw event code. These are power8 specific and not supported by PowerISA v3.0 pmu. So wrap the checks to be power8 specific. Also, "cache" bit field is referred to update MMCR1[16:17] and this check can be power8 specific.

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.
