Nove the kvm_unlink_unsync_page() call out of kvm_sync_page() and into it's sole caller, and fold __kvm_sync_page() into kvm_sync_page() since the latter becomes a pure pass-through. There really should be no reason for code to do a complete sync of a shadow page outside of the full kvm_mmu_sync_roots(), e.g. the one use case that creeped in turned out to be flawed and counter-productive. Drop the stale comment about @sp->gfn needing to be write-protected, as it directly contradicts the kvm_mmu_get_page() usage. 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.
