Well, the diffstat looks nice:

and the patches didn't trigger anything for me, but how much did this
get tested? Do you actually have both kinds of 32-bit elf mips

Linux-mips was cc'd, but I'm adding Thomas B to the cc here explicitly
just so that he has a heads-up on this thing and can go and look at
the mailing list in case it goes to a separate mailbox for him..
