Consider the following method by which an operating system might implement sema- phore instructions. Whenever the CPU is about to do an up or down on a semaphore (an integer variable in memory), it first sets the CPU priority or mask bits in such a way as to disable all interrupts. Then it fetches the semaphore, modifies it, and branches accordingly. Finally, it enables interrupts again. Does this method work if
a. There is a single CPU that switches between processes every 100 msec?
b. Two CPUs share a common memory in which the semaphore is located?
