(1) Use the existing CPUCFG6_PMNUM_SHIFT macro definition instead of the magic value 4 to get the PMU number. (2) Detect the value of PMU bits via CPUCFG instruction according to the ISA manual instead of hard-coded as 64, because the value may be different for various micro-architectures.

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.
