Add macros for AMD's PMU related CPUID features. To make it easier to
cross reference selftest code with KVM/kernel code, use the same macro
names as the kernel for the features.
For reference, the AMD APM defines the features/properties as:
* PerfCtrExtCore (six core counters instead of four)
* PerfCtrExtNB (four counters for northbridge events)
* PerfCtrExtL2I (four counters for L2 cache events)
* PerfMonV2 (support for registers to control multiple
counters with a single register write)
* LbrAndPmcFreeze (support for freezing last branch recorded stack on
performance counter overflow)
* NumPerfCtrCore (number of core counters)
* NumPerfCtrNB (number of northbridge counters)

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.
