Split the PERF_CAPABILITIES subtests into two parts so that the LBR format testcases don't execute after KVM_RUN. Similar to the guest CPUID model, KVM will soon disallow changing PERF_CAPABILITIES after KVM_RUN, at which point attempting to set the MSR after KVM_RUN will yield false positives and/or false negatives depending on what the test is trying to do. Land the LBR format test in a more generic "immutable features" test in anticipation of expanding its scope to other immutable features.

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.
