Add a test to verify the "MONITOR/MWAIT never fault" quirk, and as a bonus, also verify the related "MISC_ENABLES ignores ENABLE_MWAIT" quirk. If the "never fault" quirk is enabled, MONITOR/MWAIT should always be emulated as NOPs, even if they're reported as disabled in guest CPUID. Use the MISC_ENABLES quirk to coerce KVM into toggling the MWAIT CPUID enable, as KVM now disallows manually toggling CPUID bits after running the vCPU.

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.
