commit 94e297c50b529f5d01cfd1dbc808d61e95180ab7 upstream.
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 expansion. 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.
