Hi Paul,

 Great, thanks!  No code has used the note numbers yet as I ran out of 
time for doing the GDB side, so the change is not going to affect 
anything.

 I guess it can be backported if a need arises.  There's been clearly some 
move on the 64-bit DSP side as indicated by this GDB bug report (mentioned 
previously): <https://sourceware.org/bugzilla/show_bug.cgi?id=22286>, 
which ultimately prompted me to write this patch series, however given 
that GDB has also been broken for years it looks like just the beginning.
So maybe people will cope with the requirement to upgrade.  They need to 
notice the missing GDB part first anyway. ;)
