From d9c6d69145ec696128961204f755a3b01edc2ff6 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Sat, 21 Jul 2007 17:10:05 +0200 Subject: [PATCH] x86_64: Don't use softirq safe locks in smp_call_function It is not fully softirq safe anyways. Can't do a WARN_ON unfortunately because it could trigger in the panic case.
