Many sysfs *_show function use cpu{list,mask}_scnprintf to copy cpumap
to the buffer aligned to PAGE_SIZE, append '\n' and '\0' to return null
terminated buffer with newline.

This patch creates a new helper function cpumap_copy_to_buf in
cpumask.h and consolidates most of them using this new helper.

I assume you'll merge this via a non-PCI tree.

Yes, since it's widespread change, I prefer it to go through Greg's tree.
