[PATCH] cpusets: remove bitmap_scnprintf_len and cpumask_scnprintf_len

[Paul Jackson]

From: Paul Jackson <pj@sgi.com>

Remove bitmap_scnprintf_len and cpumask_scnprintf_len.

They aren't used.  They were briefly used as part of some
other patches to provide an alternative format for displaying
some /proc and /sys cpumasks.  They probably should have been
removed when those other patches were dropped, in favor of a
different solution.
