Apple M* parts carry some IMP DEF traps for guest accesses to PMUv3 registers, even though the underlying hardware doesn't implement PMUv3. This means it is possible to virtualize PMUv3 for KVM guests. Add a helper for mapping common PMUv3 event IDs onto hardware event IDs, keeping the implementation-specific crud in the PMU driver rather than KVM proper. Populate the pmceid_bitmap based on the supported events so KVM can provide synthetic PMCEID* values to the guest.

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.
