I notice that we don't actually have any sparc32 testing in tree. I wonder if I can steal an old debian libc image to install along with our modern-ish sparc64 compiler to get this working... Also, I've just had a look through linux/arch/sparc/kernel/sparc32.c, and see that there's more work to be done for sparcv8plus. In particular, need to save the high-half of the global and out registers. r~
