Subject: [RESEND PATCH 0/2] Make functions of dev_<level> macros, recursive vsnprintf

(Typo'ed Linus' email address, added Greg KH and netdev)
 
dev_<level> macros use a lot of repetitive string space.

Eliminate the string prefixes and function arguments from all the macro uses
and consolidate them in functions.

This patchset saves about 60K.

This implementation also adds the ability to use a struct va_format to
emit a format string along with va_list arguments.

This %pV implementation should not be used without a wrapper that
does printf argument verification like the dev_<level> functions.

Inspired a bit by Nick Andrew's patches and Linus' comments in December 2008
