From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: linux/printk.h: use unique identifier for each struct _ddebug

Changes on x86-64 later in this series require that all struct _ddebug
descriptors in a translation unit uses distinct identifiers.  Realize that
for pr_debug_ratelimited by generating such an identifier via __UNIQUE_ID
and pass that to an extra level of macros.

No functional change.
