Don't use the generic page-track mechanism to handle writes to guest PTEs in KVM's MMU. KVM's MMU needs access to information that should not be exposed to external page-track users, e.g. KVM needs (for some definitions of "need") the vCPU to query the current paging mode, whereas external users, i.e. KVMGT, have no ties to the current vCPU and so should never need the vCPU. Moving away from the page-track mechanism will allow dropping use of the page-track mechanism for KVM's own MMU, and will also allow simplifying and cleaning up the page-track APIs.

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.
