From: will.deacon@arm.com (Will Deacon) Date: Wed, 21 Nov 2018 15:07:00 +0000 Subject: [PATCH] arm64: cpufeature: Fix mismerge of CONFIG_ARM64_SSBD block Message-ID: <1542812820-24355-1-git-send-email-will.deacon@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org When merging support for SSBD and the CRC32 instructions, the conflict resolution for the new capability entries in arm64_features[] inadvertedly predicated the availability of the CRC32 instructions on CONFIG_ARM64_SSBD, despite the functionality being entirely unrelated. Move the #ifdef CONFIG_ARM64_SSBD down so that it only covers the SSBD capability.
