There are some target-specific functions that qmp_dump_guest_memory()
(and its callees) depend on. For example, see "stubs/dump.c":
- cpu_get_dump_info()
- cpu_get_note_size()
and "qom/cpu.c":
- cpu_write_elf64_note()
- etc.
These have a real implementation for the i386 and s390x targets only.
I don't know why the 1.2 changelog stated otherwise. Probably a typo /
unwanted paste from the x86 section.
