From 9b0955baa4208abd72840c13c5f56a0f133c7cb3 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 15 Sep 2020 23:00:31 +0100 Subject: [PATCH] arm64: Rename ARM64_SSBD to ARM64_SPECTRE_V4 In a similar manner to the renaming of ARM64_HARDEN_BRANCH_PREDICTOR to ARM64_SPECTRE_V2, rename ARM64_SSBD to ARM64_SPECTRE_V4. This isn't _entirely_ accurate, as we also need to take into account the interaction with SSBS, but that will be taken care of in subsequent patches.
