IMO, that's really much more error prone:

 unsigned hppa_extract_5_r_store (unsigned int);
 unsigned hppa_extract_5r_store (unsigned int);

Even easier to confuse the two...  Unless we have better, self
describing names (which would probably require someone knowing
hppa stepping in) let's leave this untouched.

What impact do you expect here?  Speaking for myself, if I review
a patch, and I see something uppercased, and I don't think it fits
right in the coding conventions, I'll say so during review.  If I feel
the uppercase is okay, I'll either remember to ask to uglify the
sources by adding an ARI expection marker, or, I'll more likely
forget it, and we'll get a nag email from the ARI script, causing
us have to do unproductive work to fix it.  Neither of the last two
options seems attractive to me.

Okay, fine with me.

In this case, between having a distracting ARI marker in the code,
and lowercasing the function name, I prefer the latter.
