Modified Files:
        src/sys/arch/i386/i386: copy.S syscall.c

Log Message:
- trace_enter/trace_exit/ktrace don't need kernel_lock.
- Use a RISC-style copyin optimised for pulling system call arguments.
  In tests I have done on Intel hardware this removes any measurable
  advantage to passing the syscall arguments in registers.
