i'm getting ready to teach a basic device drivers course in a couple
weeks with someone else's courseware and i just wanted to bring some
sections up to date.  there's one section on basic debugging that
covers printk() as well as other topics from LDD3 such as
printk_ratelimit(), setting the console loglevel and so on.

 however, there's obviously more these days -- the "pr_"-prefixed
wrappers, dev_dbg() and so on.  is there a single source that covers
the standard debugging routines in the kernel these days?  if not, no
big deal, i'll just summarize what i know of.
