Merge branch 'printk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'printk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: printk: correct the behavior of printk_timed_ratelimit() vsprintf: unify the format decoding layer for its 3 users, cleanup fix regression from "vsprintf: unify the format decoding layer for its 3 users" vsprintf: fix bug in negative value printing vsprintf: unify the format decoding layer for its 3 users vsprintf: add binary printf printk: introduce printk_once() Fix trivial conflicts (printk_once vs log_buf_kexec_setup() added near each other) in include/linux/kernel.h.
