KVM vPMU doesn't support to emulate all the fixed counters that the host PMU driver has supported, e.g. the fixed counter 3 used by Topdown metrics hasn't been supported by KVM so far. Rename MAX_FIXED_COUNTERS to KVM_PMC_MAX_FIXED to have a more straightforward naming convention as INTEL_PMC_MAX_FIXED used by the host PMU driver, and fix vPMU to use the KVM side KVM_PMC_MAX_FIXED for the virtual fixed counter emulation, instead of the host side INTEL_PMC_MAX_FIXED.

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.
