commit bc52ae0a708cb6fa3926d11c88e3c55e1171b4a1 upstream. Explicitly zero/empty-initialize the unions used for PMU related CPUID entries, instead of manually zeroing all fields (hopefully), or in the case of 0x80000022, relying on the compiler to clobber the uninitialized bitfields.

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.
