[PATCH] cpumask: comment, spacing tweaks
From: Paul Jackson <pj@sgi.com>
Tweak cpumask.h comments, spacing:
- Add comments for cpu_present_map macros: num_present_cpus() and
cpu_present()
- Remove comments for obsolete macros: cpu_set_online(),
cpu_set_offline()
- Reorder a few comment lines, to match the code and confuse readers of
this patch
- Tabify one chunk of code
