It makes a certain amount of sense to do this uniformly for all architectures -- leaving .text.* and .data.* for GCC, and using something else whenever we manually name sections. Denys' patch for parisc would need a little more thought, but it's probably worth it to be consistent. Especially if we can move more stuff out of athe arch-specific linker scripts and into -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
