  Modified files:
    sys/alpha/alpha      trap.c 
  Log:
  - Change userret() to take a struct trapframe * as its second argument and
    to extract the PC from that to send to addupc_task() so that it can be
    called from MI code.
  - Remove all traces of have_giant with extreme prejudice and use
    mtx_owned(&Giant) instead where appropriate.
  - Proc locking.
  - P_FOO -> PS_FOO.
  - Don't grab Giant just to look in curproc's p_addr during a trap since we
    may choose to immediately exit.  Instead, delay grabbing Giant a bit
    until we actually need it.
  - Don't reset 'p' to 'curproc' in syscall() to handle the case of a child
    returning from fork1() since children don't return via syscall().
  - Remove an XXX comment in ast() that questions the correctness of the
    userland check.  The code is correct.
