On architectures like PowerPC the crash notes are available for all
possible CPUs. So let's populate the elfcorehdr for all possible
CPUs having crash notes to avoid updating elfcorehdr during in-kernel
crash update on CPU hotplug events.

The similar technique is used in kexec-tool for kexec_load case.

This patch is not applying on ppc/next (53ab112a9508).

As far as I could see, crash_prepare_elf64_headers() is defined in the file
kernel/kexec_file.c and that's not recent, see babac4a84a88 (kexec_file,
x86: move re-factored code to generic side, 2018-04-13)

Am I missing something?

My mistake, sounds that your series is based on top of the Eric's one (not yet upstream):

https://lore.kernel.org/lkml/20230118213544.2128-1-eric.devolder@oracle.com/ (local)

Yes this patch series is dependent on the above patch series. In the 
next version I will
share a git repo link that will have this patch series applied along 
with dependent
patch series for easy try.
