From 6899a4c82faf9b41bbddf330651a4d1155f8b64e Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Wed, 22 Aug 2018 21:23:05 +0100 Subject: [PATCH] arm64: tlb: Use last-level invalidation in flush_tlb_kernel_range() flush_tlb_kernel_range() is only ever used to invalidate last-level entries, so we can restrict the scope of the TLB invalidation instruction.
