I will add the following to linux-next today. If the Blackfin guys
agree (or come up with something better), you should get their acks and
then add it to your tree.

Subject: [PATCH] Revert "Blackfin: use more standard pr_fmt in the module loader"
This reverts commit b75a9e6bfba5c7343391ac1bacd44d6652dde8da.
It turns out (after all this time) that referencing a function parameter
from a global macro was a bit fragile.
This could probably be done better, but this fixes a build failure due
to a commit that adds a use of pr_alert in an include file.
