From 772172697fc88cd9cd69646d878fb353f5eef516 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Wed, 20 Apr 2022 09:44:51 +0100 Subject: ARM: 9196/1: spectre-bhb: enable for Cortex-A15 [ Upstream commit 0dc14aa94ccd8ba35eb17a0f9b123d1566efd39e ] The Spectre-BHB mitigations were inadvertently left disabled for Cortex-A15, due to the fact that cpu_v7_bugs_init() is not called in that case. So fix that.
