Introduce vpmu_counter_access test for arm64 platforms. The test configures PMUv3 for a vCPU, sets PMCR_EL0.N for the vCPU, and check if the guest can consistently see the same number of the PMU event counters (PMCR_EL0.N) that userspace sets. This test case is done with each of the PMCR_EL0.N values from 0 to 31 (With the PMCR_EL0.N values greater than the host value, the test expects KVM_SET_ONE_REG for the PMCR_EL0 to fail).

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.
