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