Precisely what are you objecting to Patrick?

Are you objecting to the existence of an additional
function call in a printk or the unnecessary call to
print_mac in functions like pr_debug that the compiler
can not optimize away?

Your long list seems to be mostly a list of functions
that are converted from direct use of MAC_FMT with
6 arguments on stack to a call to print_mac.

I think the only things that should be changed are those
functions that add a useless call to print_mac because 
pr_debug is optimized away.

I do _not_ think that merely because print_mac is used
as a printk argument it should be reverted.

cheers, Joe
