In one of those comments a typo was fixed, too. Signed-off-by: Dirk Gouders Cc: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kernel/printk/printk.c: enable boot delay for earlyprintk

2013-11-13T03:09:14Z

boot_delay does not work for earlyprintk because the kernel cmdline parsing is late. Change to use early_param so early kernel messages can also be delayed. Signed-off-by: Dave Young Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kernel/printk/printk.c: convert to pr_foo()

2013-11-13T03:09:14Z

It was half-and-half. Cc: Frederic Weisbecker Cc: Greg Kroah-Hartman Cc: Joe Perches Cc: Kees Cook Cc: Tejun Heo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

printk: report console names during cut-over

2013-11-13T03:09:13Z

This reports the names of consoles as they're being disabled to help identify which is which during cut-over. Helps answer the question "which boot console actually got activated?" once the regular console is running, mostly when debugging boot console failures.

Pull tty/serial driver patches from Greg KH: "Here's the big tty/serial driver pull request for 3.12-rc1. Lots of n_tty reworks to resolve some very long-standing issues, removing the 3-4 different locks that were taken for every character.

printk: Fix return of braille_register_console()

2013-08-06T20:18:12Z

Some of my configs I test with have CONFIG_A11Y_BRAILLE_CONSOLE set. When I started testing against v3.11-rc4 my console went bonkers. Using ktest to bisect the issue, it came down to: commit bbeddf52a "printk: move braille console support into separate braille.[ch] files" Looking into the patch I found the problem. It's with the return of braille_register_console(). As anything other than NULL is considered a failure. But for those of us that have CONFIG_A11Y_BRAILLE_CONSOLE set but do not define a "brl" or "brl=" on the command line, we still may want a console that those with sight can still use. Return NULL (success) if "brl" or "brl=" is not on the console line. Signed-off-by: Steven Rostedt Acked-by: Joe Perches Cc: Andrew Morton Signed-off-by: Linus Torvalds

register_console: prevent adding the same console twice

2013-08-05T07:06:46Z

This patch guards the console_drivers list to be corrupted. The for_each_console() macro insist on a strictly forward list ended by NULL: con0->next->con1->next->NULL Without this patch it may happen easily to destroy this list for example by adding 'earlyprintk' twice, especially on embedded devices where the early console is often a single static instance. This will result in the following list: con0->next->con0 This in turn will result in an endless loop in console_unlock() later on by printing the first __log_buf line endlessly.

printk: rename struct log to struct printk_log

2013-07-31T21:41:03Z

Rename the struct to enable moving portions of printk.c to separate files. The rename changes output of /proc/vmcoreinfo. Signed-off-by: Joe Perches Cc: Samuel Thibault Cc: Ming Lei Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

printk: use pointer for console_cmdline indexing

2013-07-31T21:41:03Z

Make the code a bit more compact by always using a pointer for the active console_cmdline. Move overly indented code to correct indent level. Signed-off-by: Joe Perches Cc: Samuel Thibault Cc: Ming Lei Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

printk: move braille console support into separate braille.[ch] files

2013-07-31T21:41:03Z

Create files with prototypes and static inlines for braille support. Make braille_console functions return 1 on success. Corrected CONFIG_A11Y_BRAILLE_CONSOLE=n _braille_console_setup return value to NULL.
