Zap only leaf SPTEs in the TDP MMU's zap_gfn_range(), and rename various functions accordingly. When removing mappings for functional correctness (except for the stupid VFIO GPU passthrough memslots bug), zapping the leaf SPTEs is sufficient as the paging structures themselves do not point at guest memory and do not directly impact the final translation (in the TDP MMU). Note, this aligns the TDP MMU with the legacy/full MMU, which zaps only the rmaps, a.k.a. leaf SPTEs, in kvm_zap_gfn_range() and kvm_unmap_gfn_range().

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.
