Date: Thu, 19 Jul 2007 11:55:04 +0200 (CEST) From: Andi Kleen <ak@...e.de> To: patches@...-64.org, linux-kernel@...r.kernel.org Subject: [PATCH] [19/58] x86_64: Don't use softirq save 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.
