The patch titled
include/linux/printk.h: add pr_<level>_once macros
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: include/linux/printk.h: add pr_<level>_once macros
From: Joe Perches <joe@xxxxxxxxxxx>
- Move printk_once definitions and add an #ifdef CONFIG_PRINTK
- Add pr_<level>_once so printks can use pr_fmt
