Linux kernel vulnerability resolved for arm-smmu-v3, causing soft lockup triggered by arm_smmu_mm_invalidate_range, renamed to arm_smmu_mm_arch_invalidate_secondary_tlbs. Similar issue fixed for CPU MMU with commit 06ff87bae8d3. Solution: Clone a CMDQ_MAX_TLBI_OPS from the MAX_TLBI_OPS in tlbflush.h for SMMU using CPU page table. Replace per-page TLBI commands with a per-asid TLBI command if request size hits threshold.
