From 2ba95bcbe68d692f549fb10809f15681a25ff6fb Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Thu, 27 Mar 2008 14:05:57 -0300 Subject: [PATCH] x86: provide bogus hard_smp_processor_id We provide a bogus macro for x86_64 in case CONFIG_X86_LOCAL_APIC is not set. It will always be set for x86_64, so the effect is just to make the code equal to i386.
