Add another CPUID feature macro, VENDOR_F(), and use it to track features that KVM supports, but that need additional vendor support and so are conditionally enabled in vendor code. Currently, VENDOR_F() is mostly just documentation, but tracking all KVM-supported features will allow for asserting, at build time, take), that all features that are set, cleared, *or* checked by KVM are known to kvm_set_cpu_caps(). To fudge around a macro collision on 32-bit kernels, #undef DS to be able to get at X86_FEATURE_DS. No functional change intended.

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.
