Don't just check the raw PMU type, the only core PMU on homogeneous x86, check raw and all dynamically added PMUs. Extend the perf_pmu__warn_invalid_config to check all 4 config values. Rather than process the format list once per event, store the computed masks for each config value. Don't ignore the mask being zero, which is likely for config2 and config3, add config_masks_present so config values can be ignored only when no format information is present.

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.
