Subject: [PATCH] x86: use hard_smp_processor_id to get apic id in identify_cpu
Date: Tue, 25 Aug 2009 00:25:01 -0700 [thread overview]
Message-ID: <4A9391CD.5020804@kernel.org> (raw)
and leave phys_proc_id to use initial apic id.
otherwise, system with apci id lifting will have wrong apicid in
/proc/cpuinfo
for 2.6.31 ?
