PATCH] cpumask 11/10 comment, spacing tweaks

[Paul Jackson <pj@sgi.com>]

Andrew - If you take my other cpumask patchs, could you add this one?
	 I just noticed that my 'big cpumask comment' was a bit stale.

	 No code changes - just spacing and comments.

Tweak cpumask.h comments, spacing:

 1) Add comments for cpu_present_map macros: num_present_cpus() and cpu_present()
 2) Remove comments for obsolete macros: cpu_set_online(), cpu_set_offline()
 3) Reorder a few comment lines, to match the code and confuse readers of this patch
 3) Tabify one chunk of code
