If the host invalidates a pmd, we also have to invalidate the corresponding gmap pmds, as well as flush them from the TLB. This is necessary, as we don't share the pmd tables between host and guest as we do with ptes. The clearing part of these three new functions sets a guest pmd entry to _SEGMENT_ENTRY_EMPTY, so the guest will fault on it and we will re-link it. Flushing the gmap is not necessary in the host's lazy local and csp cases. Both purge the TLB completely.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
