Subject: [PATCH] kernel/cpu.c: document clear_tasks_mm_cpumask()

Add more comments on clear_tasks_mm_cpumask, plus adds a runtime check:
the function is only suitable for offlined CPUs, and if called
inappropriately, the kernel should scream aloud.

[akpm@linux-foundation.org: tweak comment: s/walks up/walks/, use 80 cols]
