| |
Add tdp_mmu_page into kvm_mmu_page description. tdp_mmu_page is a field to differentiate shadow pages from TDP MMU and non-TDP MMU. When TDP MMU is enabled, sp->tdp_mmu_page=1 indicates a shadow page for L1, while sp->tdp_mmu_page=0 indicates a shadow page for an L2. When TDP MMU is disabled, sp->tdp_mmu_page is always 0. So update the doc to reflect the information.
