Subject[patch 04/27] sched: fix the wrong mask_len
2.6.27-stable review patch.  If anyone has any objections, please let us 
know.

------------------
From: Miao Xie <miaox@cn.fujitsu.com>

commit c851c8676bd7ae456e9b3af8e6bb2c434eddcc75 upstream

If NR_CPUS isn't a multiple of 32, we get a truncated string of sched
domains by catting /proc/schedstat. This is caused by the wrong mask_len.

This patch fixes it.
