Subject: x86: fix show cpuinfo cpu number always zero
From: Mike Travis <travis@xxxxxxx>
Correct the problem that early_identify_cpu() sets cpu_index to '0' (needed
when called by setup_arch) after smp_store_cpu_info() had set it to the
correct value.
The error shows up in 'cat /proc/cpuinfo' will all cpus = 0.
