A few months ago I started working on a set of patches to decouple the X32 support from the 32-bit compat support. There is actually quite a bit of non-shared code between the two, mainly signal handling and syscall entries. The code used by both should be CONFIG_COMPAT, but separate config defines should be kept for the non-shared code. That would allow X32 support without dragging in all of the 32-bit compat support. I never finished it because I couldn't find a current distribution that supported X32 out of the box to test with. I agree on dropping the word emulation though, since the hardware provides a full 32-bit environment. I suggest CONFIG_X86_32_COMPAT (or CONFIG_COMPAT_X86_32) as a new name. -- Brian Gerst -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
