Hmm, some of those were used in amd64_edac at some point but then the
whole decoding code got concentrated into mce_amd.c but the exports
remained.

PP() and thus pp_msgs is still used there, for example.

So, if you'd like, you could wait until I apply Jacob's patches and push
that git branch to kernel.org and then write a patch ontop removing all
the exports except pp_msgs (you could add them to the "amd_" namespace
by calling it amd_pp_msgs or something) test that patch and send it to
me.

Thanks.
