When fed with 32-bit ELF objects such as these created by `as -32' (as invoked when building the kernel) it should convert them to 64-bit on the fly, but it wasn't really ever tested and doesn't work. There are two immediate ways to deal with that: 1. Add "-m elf32ltsmip" or "-m elf32btsmip" (depending on the endianness) to `ld' invocation (there is a commented-out example how to do this in arch/mips64/Makefile). This is probably the simplest and safest way to deal with the problem. It could probably be added to the CVS to avoid confusion. 2. Build all objects as 64-bit. This will enlarge the kernel noticeably and possibly reveal bugs. I have a patch (or maybe a hack) to enable such a setup if you were really interested. Maciej -- + Maciej W.
