From 9e8df6daed9e59153624e52aa4832ddaf39f1ae8 Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Mon, 20 Nov 2017 12:13:52 +0100 Subject: s390/smp: kasan stack instrumentation support smp_start_secondary function is called without DAT enabled. To avoid disabling kasan instrumentation for entire arch/s390/kernel/smp.c smp_start_secondary has been split in 2 parts. smp_start_secondary has instrumentation disabled, it does minimal setup and enables DAT. Then instrumentated __smp_start_secondary is called to do the rest. __load_psw_mask function instrumentation has been disabled as well to be able to call it from smp_start_secondary.
