• 61e99ab8e   printk: remove the now unnecessary "C" annotation for KERN_CONT ... Browse Code »

  Now that all KERN_ 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.

• 04d2c8c83   printk: convert the format for KERN_<LEVEL> to a 2 byte pattern ... Browse Code »

  Instead of "", use an ASCII SOH for the KERN_ 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
  "".

• 314ba3520   printk: add kern_levels.h to make KERN_<LEVEL> available for asm use ... Browse Code »

  Separate the printk.h file into 2 pieces so the definitions can be used in
  asm files.
