Add a compile-time assert in the SF() macro to detect improper usage, i.e. to detect passing in an X86_FEATURE_* flag that isn't actually scattered by the kernel. Upcoming feature flags will be 100% KVM-only and will have X86_FEATURE_* macros that point at a kvm_only_cpuid_leafs word, not a kernel-defined word. Using SF() and thus boot_cpu_has() for such feature flags would access memory beyond x86_capability[NCAPINTS] and at best incorrectly hide a feature, and at worst leak kernel state to 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 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.
