But in both of those cases we have access to meaningful virtual address
maps, which isn't true here (or certainly not trivially true!)
In xen dump-core file, (pseudo) physical address(phdr.p_paddr) is true.
This seems reasonable.
And e.g. objcopy is designed for
manipulating sections (copying out contents of a section etc).
Sections and tools like objcopy are for linking.
Program headers are for describing memory layout in virtual/physical
address.
I don't think that we want linking manipulations for core dump file.
