Yet, it can occur\nto SMMU too, since arm_smmu_mm_arch_invalidate_secondary_tlbs() is called\ntypically next to MMU tlb flush function, e.g.\n\ttlb_flush_mmu_tlbonly {\n\t\ttlb_flush {\n\t\t\t__flush_tlb_range {\n\t\t\t\t// check MAX_TLBI_OPS\n\t\t\t}\n\t\t}\n\t\tmmu_notifier_arch_invalidate_secondary_tlbs {\n\t\t\tarm_smmu_mm_arch_invalidate_secondary_tlbs {\n\t\t\t\t// does not check MAX_TLBI_OPS\n\t\t\t}\n\t\t}\n\t}\n\nClone a CMDQ_MAX_TLBI_OPS from the MAX_TLBI_OPS in tlbflush.h, since in an\nSVA case SMMU uses the CPU page table, so it makes sense to align with the\ntlbflush code. Then, replace per-page TLBI commands with a single per-asid\nTLBI command, if the request size hits this threshold."
