All ARM TLB maintenance operations have both "this CPU only" and "all TLBs in the Inner Shareable domain" [that's ARM-speak for "every CPU core in the cluster"] variants (the latter being the TLB *IS operations). Looking at Linux's arch/arm64/mm/tlb.S and arch/arm64/include/asm/tlbflush.h most of the operations defined there use the IS variants. -- PMM
