From 6e179d64126b909f0b288fa63cdbf07c531e9b1d Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Fri, 23 Mar 2018 13:04:49 +0100 Subject: s390: add automatic detection of the spectre defense Automatically decide between nobp vs. expolines if the spectre_v2=auto kernel parameter is specified or CONFIG_EXPOLINE_AUTO=y is set. The decision made at boot time due to CONFIG_EXPOLINE_AUTO=y being set can be overruled with the nobp, nospec and spectre_v2 kernel parameters.
