 Please note that n32 is a MIPS64 ABI (an ILP32 ABI requiring a 64-bit 
processor).

 Please resend with a description clearly stating what problem you intend 
to solve, such that it can be used as the commit message.  If sending a 
GIT-formatted patch, then place any comments not to be committed after the
`---' separator (there is no requirement to send GIT-formatted patches for 
this project though).

 Do not include an update to any ChangeLog files with the patch itself; it 
will cause a conflict when the patch is applied.  Include the intended 
ChangeLog entries at the end of the description instead, and the committer 
will apply them as appropriate.

 Why only update elf32-mips.c and elf64-mips.c and not elfn32-mips.c?

 Also did you verify your change and if so, then how?  When submitting a 
change please always say how it has been tested.

 Finally, I see this is your first patch posted, so please clarify if you 
have a copyright assignment in place with FSF.  This is a very small 
change, so it's likely that it can go in even without such an assignment,
however it would be preferable that you had it, and it will be a 
requirement if you intend to submit more changes.

 Please let me know if you have any questions.
