#     Pull kvm fixes from Paolo Bonzini:
#      "KVM GUEST_MEMFD fixes for 6.8:
#     
#        - Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY
#          to avoid creating an inconsistent ABI (KVM_MEM_GUEST_MEMFD is not
#          writable from userspace, so there would be no way to write to a
#          read-only guest_memfd).
#     
#        - Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
#          clear that such VMs are purely for development and testing.
#     
#        - Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term
#          plan is to support confidential VMs with deterministic private
#          memory (SNP and TDX) only in the TDP MMU.
#     
#        - Fix a bug in a GUEST_MEMFD dirty logging test that caused false
#          passes.
#     
#       x86 fixes:
#     
#        - Fix missing marking of a guest page as dirty when emulating an
#          atomic access.
#     
#        - Check for mmu_notifier invalidation events before faulting in the
#          pfn, and before acquiring mmu_lock, to avoid unnecessary work and
#          lock contention with preemptible kernels (including
#          CONFIG_PREEMPT_DYNAMIC in non-preemptible mode).
#     
#        - Disable AMD DebugSwap by default, it breaks VMSA signing and will
#          be re-enabled with a better VM creation API in 6.10.
#     
#        - Do the cache flush of converted pages in svm_register_enc_region()
#          before dropping kvm->lock, to avoid a race with unregistering of
#          the same region and the consequent use-after-free issue"
#
