[RFC PATCH 0/3] printk: Use a non-printable ASCII SOH for KERN_<LEVEL>

[Joe Perches]

printk uses "<.>" as a start of record indicator.
This can waste a bit of space and causes a bit of
contortion to get a printk emitted that happens to
starts with "<.>".

Use ASCII Start-of-Header (0x01) as the KERN_LEVEL
initiator and save ~10K in an x86 defconfig.

Joe Perches (3):
  printk: Use a non-printable ASCII KERN_<LEVEL> initiator
  treewide: Fix declaration and uses of old KERN_<LEVEL> style
  printk: Set KERN_CONT to ""
