Use a more current logging style.
Convert the remaining printks without a KERN_<PREFIX>
to pr_<level> where appropriate.
There a few additional printks without a level that
are emitted at KERN_DEFAULT for stack dumps and such.
Add printf format/argument verification to the static
inline just in case.
