   I'm not sure who the maintainer for this is.  

   This change factors out some repeated code into a function, cleans it
   up a bit, and then adds a new use of that function.  It allows GDB to
   understand '.reg-xfp' notes in Linux core files.  I've submitted
   corresponding patches to BFD and the Linux kernel itself, but this
   change should be harmless until those patches are applied.

This looks like a good set of changes, thanks.  Try running through
indent however; I saw a couple places where I think indent might
something different than what you did.
