[Moore, Robert] I take it that __udivdi3 is a 64-bit divide? We do have a local divide implementation(s) for things like this. However, I don't see a divide in ut_insert_digit; There is a 64-bit divide in ut_strtoul_add_64, however. So, there are no issues with 64-bit add, subtract, and multiply? > > Thanks, > Rafael -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
