Track the mask of "unavailable" PMU events as a 32-bit value. While bits 31:9 are currently reserved, silently truncating those bits is unnecessary and asking for missed coverage. To avoid running afoul of the sanity check in vcpu_set_cpuid_property(), explicitly adjust the mask based on the non-reserved bits as reported by KVM's supported CPUID. Opportunistically update the "all ones" testcase to pass -1u instead of 0xff.

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.
