Hi,

Just a quick update on working with OpenMPI's MIPS
code on the MIPS64 processor. It does not appear to
work to simply use the atomic code for the 32-bit MIPS
- the opcodes don't correspond. Over the next day or
two, I will be updating the assembler on the MIPS64
board, and I'll know better then whether this is a
genuine problem or a phantom issue.

(If someone's developed a patch by then, so much the
better, but I'm going to keep working on this
possibility for the immediate future.)
