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.

Hi guys,
It's been a while since I sent this one. Can we please merge it if
there is no objections?
Thanks.
