Sean Christopherson 157fc497b5 KVM: x86: Ignore benign host accesses to "unsupported" PEBS and BTS MSRs
Ignore host userspace reads and writes of '0' to PEBS and BTS MSRs that
KVM reports in the MSR-to-save list, but the MSRs are ultimately
unsupported.  All MSRs in said list must be writable by userspace, e.g.
if userspace sends the list back at KVM without filtering out the MSRs it
doesn't need.

Fixes: 8183a538cd ("KVM: x86/pmu: Add IA32_DS_AREA MSR emulation to support guest DS")
Fixes: 902caeb684 ("KVM: x86/pmu: Add PEBS_DATA_CFG MSR emulation to support adaptive PEBS")
Fixes: c59a1f106f ("KVM: x86/pmu: Add IA32_PEBS_ENABLE MSR emulation for extended PEBS")

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.
