get_scattered_cpuid_leaf() was added[1] to help KVM rebuild hardware- defined leafs that are rearranged by Linux to avoid bloating the x86_capability array. Eventually, the last consumer of the function was removed[2], but the function itself was kept, perhaps even intentionally as a form of documentation. Remove get_scattered_cpuid_leaf() as it is currently not used by KVM. Furthermore, simply rebuilding the "real" leaf does not resolve all of KVM's woes when it comes to exposing a scattered CPUID feature, i.e. keeping the function as documentation may be counter-productive in some scenarios, e.g. when KVM needs to do more than simply expose the leaf.

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.
