So I saw this title:

   [PATCH] x86, cpuinfo x86_model_id whitespace cleanup

... and in an early morning deconcentrated state was skipped the 
changelog and was looking for a whitespace coding style cleanup:

Which this clearly isnt!

Fortunately before complaining about that I read the changelog as 
well, and realized that the 'whitespace cleanup' is done to 
/proc/cpuinfo ABI output.

Could you please make the title less ambiguous, so that sleepy kernel 
developers get the right idea what the patch looks like, from the 
title alone? Git shortlogs will vastly improve as well.

Something like:

   [PATCH] x86/cpu: Strip leading and trailing spaces from the /proc/cpuinfo CPU model field

... or so would work very well for me!

Thanks,

	Ingo
