Call kvm_mmu_zap_all_fast() directly when flushing a memslot instead of bouncing through the page-track mechanism. KVM (unfortunately) needs to zap and flush all page tables on memslot DELETE/MOVE irrespective of whether KVM is shadowing guest page tables. This will allow changing KVM to register a page-track notifier on the first shadow root allocation, and will also allow deleting the misguided kvm_page_track_flush_slot() hook itself once KVM-GT also moves to a different method for reacting to memslot changes. 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.
