  Modified files:
    sys/amd64/amd64      trap.c 
  Log:
  In syscall, always make a copy of parameters from trapframe, this
  becauses some syscalls using set_mcontext can sneakily change
  parameters and later when those syscalls references parameters,
  they will wrongly use register values in mcontext_t.
