The manpage for delay(9) suggests that the prototype is: void delay(int);
But on armv7, arm64, hppa, macppc, and powerpc64 the input is unsigned or a u_int instead of an int. Like this: void delay(unsigned); or this: void delay(u_int); Can we pick a prototype and stick to it? An upside of an unsigned input is a larger usable input range. A negative input to delay(9) makes no sense anyway. On the other hand, we could KASSERT a non-negative value and catch bugs if the input were signed. Also, the input should, in general, be small. We probably don't really need the extra range. A large input might itself indicate a bug. In any case, I want the prototypes to match up across platforms. What do people prefer? Signed int or unsigned int?
