The code is in the file:kexec-tools/kexec/crashdump-elf.c
nr_cpus = sysconf(_SC_NPROCESSORS_CONF);

kexec-tools always allocates program headers for each possible cpu. This
incurs zero PT_NOTE for offline cpu. We mark this case so that later,
the capture kernel can distinguish it from the mistake of allocated
program header.
The counterpart of the capture kernel comes in next patch.
kexec-tools always allocates program headers for possible cpus. But
when crashing, offline cpus have dummy headers. We do not copy these
dummy notes into ELF file, also have no need of warning on them.
