From 36c602dcdd872e9f9b91aae5266b6d7d72b69b96 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Tue, 29 Oct 2019 16:27:38 -0700 Subject: arm64: cpufeature: Enable Qualcomm Falkor errata 1009 for Kryo The Kryo cores share errata 1009 with Falkor, so add their model definitions and enable it for them as well.

Since there are now multiple entries to match, we must convert the existing ARM64_ERRATUM_845719 into an erratum list.
