Track the per-vendor required APICv inhibits with a variable instead of calling into vendor code every time KVM wants to query the set of required inhibits. The required inhibits are a property of the vendor's virtualization architecture, i.e. are 100% static. Using a variable allows the compiler to inline the check, e.g. generate a single-uop TEST+Jcc, and thus eliminates any desire to avoid checking inhibits for performance reasons. 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 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.
