Yesterday, I thought what I wanted to do was the ".c" file equivalent of
the '.section .alphalib,"ax"' substitution we made to the ".S" files.
I'm getting a good kernel build with the following patch:

====--TUC EREH--====
The GNU C documentation concerning the "section" attribute as applied to
functions implies I should have been able to specify
__attribute__((section(".alphalib,\"ax\"")))
but the compiler didn't like the comma and argument following the
section name.
I'm guessing I'll probably end up having to do this same fixup for the
rest of the ".c" files in the "arch/alpha/lib" directory at some point,
but I'll cross that bridge when I come to it.
