From 191adcc50e1155331b230d0120100b211ea2c032 Mon Sep 17 00:00:00 2001 From: Diana Craciun Date: Fri, 29 Mar 2019 22:26:10 +1100 Subject: [PATCH] powerpc/fsl: Fix spectre_v2 mitigations reporting commit 7d8bad99ba5a22892f0cad6881289fdc3875a930 upstream. Currently for CONFIG_PPC_FSL_BOOK3E the spectre_v2 file is incorrect: $ cat /sys/devices/system/cpu/vulnerabilities/spectre_v2 "Mitigation: Software count cache flush" Which is wrong. Fix it to report vulnerable for now.
