Markus Armbruster d8592b05be hw/arm: do not free machine->fdt in arm_load_dtb() ... At this moment, arm_load_dtb() can free machine->fdt when binfo->dtb_filename is NULL. If there's no 'dtb_filename', 'fdt' will be retrieved by binfo->get_dtb(). If get_dtb() returns machine->fdt, as is the case of machvirt_dtb() from hw/arm/virt.c, fdt now has a pointer to machine->fdt. And, in that case, the existing g_free(fdt) at the end of arm_load_dtb() will make machine->fdt point to an invalid memory region. Since monitor command 'dumpdtb' was introduced a couple of releases ago, running it with any ARM machine that uses arm_load_dtb() will crash QEMU. Let's enable all arm_load_dtb() callers to use dumpdtb properly. Instead of freeing 'fdt', assign it back to ms->fdt.
