You might like to include their names and email addresses in the 
appropriate ChangeLog entries, so they are credited for the work that 
they have done.

I did have a look over the patch, but there was nothing glaring that I 
thought might cause problems.  One thing that you might like to consider 
now that this patch has been comitted is to upgrade the xtensa specific 
files (eg: tc-xtensa.c, tc-xtensa.h, elf32-xtensa.c, xtensa-dis.c) to 
ISO C90.
