Add a helper to determine whether or not a full TLB flush needs to be performed on nested VM-Enter/VM-Exit, as the logic is identical for both flows and needs a fairly beefy comment to boot. This also provides a common point to make future adjustments to the logic. Handle vpid12 changes the new helper as well even though it is specific to VM-Enter. The vpid12 logic is an extension of the flushing logic, and it's worth the extra bool parameter to provide a single location for the flushing logic.

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.
