In Eric's sample, it's intended to prevent there being an empty section,
which can cause linker bugs. In your case it probably isn't necessary,
since you're also putting the percpu data in that section.

"DATA" is probably a typo. It should be "LONG" or something like that.
(See "3.6.5 Output Section Data" in the linker manual.)
