ctags indexing ("make tags" command) throws this warning:
ctags: Warning: include/linux/notifier.h:125:
null expansion of name pattern "\1"
This is the result of DEFINE_PER_CPU() macro exapansion. Fix that by
getting rid of line break.
Similar fix was already done in commit 25528213fe9f ("tags: Fix
DEFINE_PER_CPU expansions"), but this one probably wasn't noticed.

This one was sent some time ago, but there wasn't any response. Can
you please review it and merge if applicable?
Thanks!
