this broke the x86 build:
arch/x86/kernel/cpu/common.c: In function 'early_identify_cpu':
arch/x86/kernel/cpu/common.c:553: error: 'struct cpuinfo_x86' has no member named 'cpu_index'
fixed via the patch below.

Subject: [PATCH] x86: cpu_index build fix
fix:
arch/x86/kernel/cpu/common.c: In function 'early_identify_cpu':
arch/x86/kernel/cpu/common.c:553: error: 'struct cpuinfo_x86' has no member named 'cpu_index'
as cpu_index is only available on SMP.
