Commit Message

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!

Why not to add Fixes tag here as well?
