Subject: Re: [PATCH 1/1] x86: convert-cpuinfo_x86-array-to-a-per_cpu-array
 fix

Hi Andrew,

It appears that this patch is missing from the latest 2.6.24 git kernel?

(Suresh noticed that it is still a problem.)

Thanks,
Mike

This fix corrects 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.
