Subject: not needed patch

Ingo.

commit fbdcf18df73758b2e187ab94678b30cd5f6ff9f9  is not needed. 
another patch  (by you !! commit 699d934d5f958d7944d195c03c334f28cc0b3669  x86: fixup cpu_info array conversion)
already removed clearing of c->cpu_index. in identify_cpu

also it is not consisent to smpboot_32.c. (it will assign id to cpu_index right after 
 	*c = boot_cpu_data;
)

by revert commit fbdcf18df73758b2e187ab94678b30cd5f6ff9f9, we could use c->cpu_index in identify_cpu.

    correct value.
    
    The error shows up in 'cat /proc/cpuinfo' will all cpus = 0.
