164  * some code paths that need to defer all printk console printing. Interrupts
291  * printk_cpu_sync_get_irqsave() - Disable interrupts and acquire the printk
321  * printk_cpu_sync_put_irqrestore() - Release the printk cpu-reentrant spinning
334  * pr_fmt - used by the pr_*() macros to generate the printk format string
360 	 * While printk and pr_* have the level stored in the string at compile

407  * Some subsystems have their own custom printk that applies a va_format to a

434  * printk - print a kernel message
437  * This is printk(). It can be called from any context. We want it to work.
439  * If printk indexing is enabled, _printk() is called from printk_index_wrap.
440  * Otherwise, printk is simply #defined to _printk.
448  * One effect of this deferred printing is that code which calls printk() and
457 #define printk(fmt, ...) printk_index_wrap(_printk, fmt, ##__VA_ARGS__)
466  * This macro expands to a printk with KERN_EMERG loglevel. It uses pr_fmt() to
470 	printk(KERN_EMERG pr_fmt(fmt), ##__VA_ARGS__)
476  * This macro expands to a printk with KERN_ALERT loglevel. It uses pr_fmt() to
480 	printk(KERN_ALERT pr_fmt(fmt), ##__VA_ARGS__)
486  * This macro expands to a printk with KERN_CRIT loglevel. It uses pr_fmt() to
490 	printk(KERN_CRIT pr_fmt(fmt), ##__VA_ARGS__)
496  * This macro expands to a printk with KERN_ERR loglevel. It uses pr_fmt() to
500 	printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__)
506  * This macro expands to a printk with KERN_WARNING loglevel. It uses pr_fmt()
510 	printk(KERN_WARNING pr_fmt(fmt), ##__VA_ARGS__)
516  * This macro expands to a printk with KERN_NOTICE loglevel. It uses pr_fmt() to
520 	printk(KERN_NOTICE pr_fmt(fmt), ##__VA_ARGS__)
526  * This macro expands to a printk with KERN_INFO loglevel. It uses pr_fmt() to
530 	printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__)
537  * This macro expands to a printk with KERN_CONT loglevel. It should only be
542 	printk(KERN_CONT fmt, ##__VA_ARGS__)
549  * This macro expands to a printk with KERN_DEBUG loglevel if DEBUG is
