 Recent versions of qemu will no longer print the "Trying to execute
 code outside RAM or ROM" message, as the code to do that was removed
 in the following qemu commit:

       accel/tcg: Return -1 for execution from MMIO regions in get_page_addr_code()
 
       Now that all the callers can handle get_page_addr_code() returning -1,
       remove all the code which tries to handle execution from MMIO regions
       or small-MMU-region RAM areas. This will mean that we can correctly
       execute from these areas, rather than ending up either aborting QEMU
       or delivering an incorrect guest exception.

 The problem remains, though - attempts by NetBSD to reboot itself
 still frequently fail, but now by silently hanging instead of printing
 the "Trying to execute code outside RAM or ROM" message.
