Set the eventsel for all fixed counters during PMU initialization, the eventsel is hardcoded and consumed if and only if the counter is supported, i.e. there is no reason to redo the setup every time the PMU is refreshed. Configuring all KVM-supported fixed counter also eliminates a potential pitfall if/when KVM supports discontiguous fixed counters, in which case configuring only nr_arch_fixed_counters will be insufficient (ignoring the fact that KVM will need many other changes to support discontiguous fixed 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 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.
