From 71b31233a215be27e2efbcc0e739cbebb0bde078 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Fri, 19 Oct 2007 20:35:03 +0200 Subject: x86: acpi use cpu_physical_id This is from an earlier message from Christoph Lameter: processor_core.c currently tries to determine the apicid by special casing for IA64 and x86. The desired information is readily available via cpu_physical_id() on IA64, i386 and x86_64. Signed-off-by: Christoph Lameter Additionally, boot_cpu_id needed to be exported to fix compile errors in dma code when !CONFIG_SMP.
