It looks like kernel math emulation is much more broken. e.g. kernel_fpu_begin() is missing code and lots of other paths in i387 that need to check HAVE_HWFP don't. Fixing it properly would be much more work. Since it evidently hasn't worked for a long time I'm thinkin about just marking it CONFIG_BROKEN and deprecating it for 2.6.20 Comments? -Andi - 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/
