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 <clameter@sgi.com> Additionally, boot_cpu_id needed to be exported to fix compile errors in dma code when !CONFIG_SMP.
