When zapping a GFN in response to an APICv or MTRR change, don't zap SPTEs for invalid roots as KVM only needs to ensure the guest can't use stale mappings for the GFN. Unlike kvm_tdp_mmu_unmap_gfn_range(), which must zap "unreachable" SPTEs to ensure KVM doesn't mark a page accessed/dirty, kvm_tdp_mmu_zap_leafs() isn't used (and isn't intended to be used) to handle freeing of host memory.

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.
