OK, I asked the corresponding maintainers to review them.

I think that it was my mistake that I referred to makedumpfile-related
VMCOREINFO's in my patch.
Since I'm not a user nor author of makedumpfile command for arm64,
my changes should have been minimized, exluding any non-mandatory symbols.
(Patch#13/14 is necessary for me to verify generated vmcore files
with crash utility.)
So I asked Pratyush to post his kernel patch based on his own requirements
as he wants.
I believe it's fair enough.

Since I've got no comments on kdump patches and had no updates
so far, I don't plan to post v21 this week (at this point).
(I will add "reviewed-by James" to patch#7/14 in future releases.)
