[PATCH V2 0/3] recursive printk, make functions from logging macros

From: Joe Perches
Date: Fri Mar 05 2010 - 01:57:16 EST

dev_<level> macros use a lot of repetitive string space and arguments
pr_<level> macros use repetitive unnecessary KERN_<level> strings

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

This patchset saves about 60K of text in an x86 defconfig.

This implementation 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

vsprintf: Recursive vsnprintf: Add "%pV", struct va_format
device.h drivers/base/core.c Convert dev_<level> macros to functions
kernel.h kernel/printk.c: Convert pr_<level> macros to functions
