Yeah, we should restore the old behaviour. The timestamp is always
stored internally, regardless of the CONFIG_PRINTK_TIME or tunable
setting. At the moment, seems they are only (conditionally) added to
the syslog() output and (unconditionally) to the /dev/kmsg export.
I guess we just re-define CONFIG_PRINTK_TIME and the tunable as: "show
time in syslog() and on the console output".
Karel will likely extend dmesg(1) to use /dev/kmsg instead of syslog()
when it's readable and dmesg(1) can still show the time stamps read
from /dev/kmsg, even when CONFIG_PRINTK_TIME is not set, so the old
tunable basically becomes a "show timestamps on the console" flag. :)
