It's almost always true that using
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
before any #include

and changing all pr_<level>( uses from

	pr_<level>("s: etc...", KBUiLD_MODNAME, ...)
to
	pr_<level>("etc...", ...)

produces overall smaller object code.
That's even more likely for 64 bit compiled code.
