Ensuring that all the threads of a given process share an address space in an SMP is (select one from the following to complete the sentence)

• impossible

• trivially achieved since the page table is in shared memory

• achieved by careful replication of the page table by the operating system for each thread

• achieved by the hardware providing cache coherence
