From: Stijn Tintel <stijn@linux-ipv6.be> Date: Tue, 31 Jul 2018 09:19:18 +0000 (+0300) Subject: kernel: add missing ARM64_SSBD symbol X-Git-Tag: v18.06.1~50 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6c075777d5afdeef7516e5125526b3f2c406f453;p=oweals%2Fopenwrt.git kernel: add missing ARM64_SSBD symbol In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for ARM64. Add this symbol to all ARM64 targets using kernel 4.14. This mitigates CVE-2018-3639 on ARM64.
