Please don't do this. Let's not invent new interfaces here. Let's just
stick to traditional syslog which is perfectly capable of handling this,
because it allows for a full 8bit number between < and > which is 3 bits
priority plus 5 bits facility.

Then, let's fix the kernel side of kmsg to implicitly add in LOG_USER as
facility for everything coming in from /dev/kmsg that has has facility=0
set. 

Basically what Kay suggested.

Facilities might not be the most powerful idea ever invented, but they
are useful to distuingish kernel from userspace messages, as there is
LOG_KERNEL for the former and all other facilities for the latter.
