I guarantee you're going to end up fixing this issue over and over again as more
code is added in.

This is certainly going to happen, but it should be quickly spotted by
anybody running make tags on linux-next. And 10 instances since the
beginning of git is not too many.

OOC, why not fix ctags to recognize newlines?

It's not ctags itself parsing the DEFINE_PER_CPU() macro, but a
user-supplied regex specified on commandline. Which can only operate on
single lines.
