        Remove trace_buf_size and trace_event from the kernel bootparameters of the kdump kernel
    
        The kdump kernel uses resources for ftrace because trace_buf_size, which
        specifies the ring buffer size for ftrace, and trace_event, which specifies
        a valid trace event, are not removed, but the kdump kernel does not require
        ftrace.
    
        trace_buf_size is ignored if the specified size is 0, so specify 1.
