    This installs the machine name as recorded by setup_machine_fdt()
    as dump stack arch description. This results in the string to be
    included in call stack dumps, as is shown here:
    
      ...
      Bad mode in Synchronous Abort handler detected, code 0x84000005
      CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.18.0-rc2+ #548
    > Hardware name: linux,dummy-virt (DT)
      task: ffffffc07c870000 ti: ffffffc07c878000 task.ti: ffffffc07c878000
      PC is at 0x0
      ...
    
    Note that systems that support DMI/SMBIOS may override this later.
