* printk: remove the now unnecessary "C" annotation for KERN_CONTJoe Perches2012-07-301-1/+1
| | | | | | | | | | | | | Now that all KERN_<LEVEL> uses are prefixed with ASCII SOH, there is no need for a KERN_CONT. Keep it backward compatible by adding #define KERN_CONT "" Reduces kernel image size a thousand bytes.

* printk: convert the format for KERN_<LEVEL> to a 2 byte patternJoe Perches2012-07-301-11/+14
| | | | | | | | | | | | | | Instead of "<.>", use an ASCII SOH for the KERN_<LEVEL> prefix initiator. This saves 1 byte per printk, thousands of bytes in a normal kernel. No output changes are produced as vprintk_emit converts these uses to "<.>".

* printk: add kern_levels.h to make KERN_<LEVEL> available for asm useJoe Perches2012-07-301-0/+22
Separate the printk.h file into 2 pieces so the definitions can be used in asm files. Signed-off-by: Joe Perches <joe@perches.com> Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
