Patch 2 fixes a small issue that only shows up with patch 3. Patches 3+4 add some space optimizations by omitting unneeded code. They are _not_ required, the main part is patch 1. TODO: - which CPUs exactly need X86_ALIGNMENT_16? - change include/asm-i386/module.h to use some kind of bitmask cu Adrian - 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/
