[PATCH tip] Fix build failure x86_default_fixup_cpu_id() with !CONFIG_SMP

[Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>]

Hi,

tip (a4a7e7e29333) build fails, when compiled with !CONFIG_SMP. 
I have only build tested the patch.

x86: Fix x86_default_fixup_cpu_id() build failure with !CONFIG_SMP

arch/x86/kernel/cpu/common.c: In function 'x86_default_fixup_cpu_id':
arch/x86/kernel/cpu/common.c:1149: error: 'struct cpuinfo_x86' has no member named 'phys_proc_id'
make[3]: *** [arch/x86/kernel/cpu/common.o] Error 1

the code was introduced by commit 64be4c1c24. This patch
introduced #ifdef to guard !SMP case.
