Drop KVM's odd restriction that disallows clearing CPUID_FAULT in MSR_PLATFORM_INFO if CPL>0 CPUID faulting is enabled in MSR_MISC_FEATURES_ENABLES. KVM generally doesn't require specific ordering when userspace sets MSRs, and the completely arbitrary order of MSRs in emulated_msrs_all means that a userspace that uses KVM's list verbatim could run afoul of the check. Dropping the restriction obviously means that userspace could stuff a nonsensical vCPU model, but that's the case all over KVM. KVM typically restricts userspace MSR writes only when it makes things easier for KVM and/or userspace.

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.
