I'm not sure whether you are testing ppc on a dumpfile or a live
system using /dev/mem, and I don't know what your paddr value and
vs your vt->high_memory are.
But I'm testing x86_64 on a live system with the crash memory
driver, so DEVMEM is not set. And as it turns out, it doesn't
print the header because it returns here:
if (!(section = valid_section_nr(section_nr))) {
#ifdef NOTDEF
break; /* On a real sparsemem system we need to check
* every section as gaps may exist. But this
* can be slow. If we know we don't have gaps
* just stop validating sections when we
* get to the end of the valid ones.
* In the future find a way to short circuit
* this loop.

#endif
if (mi->flags & ADDRESS_SPECIFIED)
break;
continue;
}
if (print_hdr) {
