Assert that mmu->sync_page is non-NULL as part of the sanity checks performed before attempting to sync a shadow page. Explicitly checking mmu->sync_page is all but guaranteed to be redundant with the existing sanity check that the MMU is indirect, but the cost is negligible, and the explicit check also serves as documentation.

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.
