Wei Yang e7912386ed KVM: x86: reintroduce pte_list_remove, but including mmu_spte_clear_track_bits
rmap_remove() removes the sptep after locating the correct rmap_head but,
in several cases, the caller has already known the correct rmap_head.

This patch introduces a new pte_list_remove(); because it is known that
the spte is present (or it would not have an rmap_head), it is safe
to remove the tracking bits without any previous check.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
