This simplifies set_spte, which we want to remove, and unifies code between the shadow MMU and the TDP MMU. The warning will be added back later to make_spte as well. There is a small disadvantage in the TDP MMU; it may unnecessarily mark a page as dirty twice if two vCPUs end up mapping the same page twice. However, this is a very small cost for a case that is already rare. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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.
