Leo Yan 33e1fffea4 perf arm_spe: Fix memset subclass in operation
The operation subclass is extracted from bits [7..1] of the payload.
Since bit [0] is not parsed, there is no chance to match the memset type
(0x25). As a result, the memset payload is never parsed successfully.

Instead of extracting a unified bit field, change to extract the
specific bits for each operation subclass.

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.
