* Arrange for a function to be invoked neatly, after a cpu_switch().
*
* Invokes fork_exit() passing in three arguments: a callout function,
* a pointer to the executing process's proc structure, and a trapframe
* pointer.
* an argument to the callout, and a trapframe pointer. For child processes
* returning from fork(2), the argument is a pointer to the child process.
*
* The callout function is in s0, the address to return to after executing
* fork_exit() is in s1, and the argument is in s2.
