[PATCH tip/core/rcu 04/12] rcu: Glue ASCII strings together

From: Paul E. McKenney
Date: Mon Feb 17 2014 - 16:38:06 EST


From: Joe Perches <joe@xxxxxxxxxxx>

Split strings make it difficult to find the code that resulted in a
given console message, so this commit glues split strings back together
despite the resulting long lines.
