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.

When clearing TDP MMU pages what have been disconnected from the paging structure root, set the SPTEs to a special non-present value which will not be overwritten by other threads. This is needed to prevent races in which a thread is clearing a disconnected page table, but another thread has already acquired a pointer to that memory and installs a mapping in an already cleared entry. This can lead to memory leaks and accounting errors. Reviewed-by:Peter Feiner <pfeiner@google.com> Signed-off-by:
