Everything is in place now for KVM to actually handle MDCR_EL2.HPMN. Not only that, the emulation is capable of doing FEAT_HPMN0. Advertise support for the feature in the VM's ID registers. It is possible to emulate FEAT_HPMN0 on hardware that doesn't support it since KVM currently traps all PMU registers. Having said that, let's only advertise the feature on supporting hardware in case KVM ever provides 'direct' PMU support to VMs w/o involving host perf.

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.
