Wondering why this need be updated.
In some architectures, additional kexec segments become obsolete during a
hotplug event,
so simply calling out the `elfcorehdr may be inaccurate` may not be
sufficient.
Therefore, it has been generalized with the kdump image.
OK, I forgot the case in ppc, makes sense to me, thx.
