From 66d16ed45d19600abd72dbd55bd2018437b24b73 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Fri, 19 Oct 2007 20:35:03 +0200 Subject: x86: implement missing x86_64 function smp_call_function_mask() This patch defines the missing function smp_call_function_mask() for x86_64, this is more or less a cut&paste of i386 function. It removes also some duplicate code. This function is needed by KVM to execute a function on some CPUs. AK: Fixed description AK: Moved WARN_ON(irqs_disabled) one level up to not warn in the panic case.
