Merge tag 'kvm-x86-mmu-6.8' of https://github.com/kvm-x86/linux into HEAD

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.
