From: Marc Zyngier Date: Wed, 1 Feb 2017 14:38:46 +0000 (+0000) Subject: arm64: cpu_errata: Allow an erratum to be match for all revisions of a core X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=06f1494f837da8997d670a1ba87add7963b08922;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git arm64: cpu_errata: Allow an erratum to be match for all revisions of a core Some minor erratum may not be fixed in further revisions of a core, leading to a situation where the workaround needs to be updated each time an updated core is released. Introduce a MIDR_ALL_VERSIONS match helper that will work for all versions of that MIDR, once and for all.
