Joe Perches	61e99ab8e3	printk: remove the now unnecessary "C" annotation for KERN_CONT ... 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.

Joe Perches	04d2c8c83d	printk: convert the format for KERN_<LEVEL> to a 2 byte pattern ... 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 "<.>".

Joe Perches	314ba3520e	printk: add kern_levels.h to make KERN_<LEVEL> available for asm use ... Separate the printk.h file into 2 pieces so the definitions can be used in asm files.
