Explain why spinlocks are not appropriate for single-processor systems yet are often used in multiprocessor systems?

A spinlock is basically a loop that constantly checks a condition until it is true. Think of a bunch of kids in the back of a car saying "Are we there yet...are we there yet...are we there yet...". This is a poor implementation for almost any setup, since the lock is wasting processor time that could be doing something more efficient than constantly checking a condition over and over. Also, while the spinlock is running on the processor, the system will be completely unresponsive.

Explain why implementing synchronization primitives by disabling interrupts is not appropriate in a single-processor system if the synchronization primitives are to be used in user-level programs?
Interrupts are not sufficient in multiprocessor systems since disabling inter rupts only prevents other processes from executing on the processor in which inter rupts were disabled; there are no limitations on what processes could be executing on other processors and therefore the process disabling interrupts cannot guarantee mutually exclusive access to program state.
