Paolo Bonzini 7f26fea9bc KVM x86 MMU changes for 6.8:
- Fix a relatively benign off-by-one error when splitting huge pages during
    CLEAR_DIRTY_LOG.
 
  - Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf
    TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE.
 
  - Relax the TDP MMU's lockdep assertions related to holding mmu_lock for read
    versus write so that KVM doesn't pass "bool shared" all over the place just
    to have precise assertions in paths that don't actually care about whether
    the caller is a reader or a writer.

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.
