The TTL field indicates the level of page table walk holding the *leaf*
entry for the address being invalidated. But currently, the TTL field
may be set to an incorrent value in the following stack:

pte_free_tlb
    __pte_free_tlb
        tlb_remove_table
            tlb_table_invalidate
                tlb_flush_mmu_tlbonly
                    tlb_flush

[...]
