How sweet life would be without the SGI designed ELF NABI. For the purposes of kernel modules that means 64-bit MIPS kernels. The 64-bit ELF spec [1] allows both REL and RELA. I believe that GNU tools only emit rela relocations and in the hope that things are going to stay like this I'd like 64-bit MIPS to be treated as RELA-only. However we're in the hand of the tools guy here - they always could make use of the rope provided. 32-bit MIPS uses REL only.
