[Crash-utility] [PATCHv8 0/4] crash-utility/arm64: memory layout bug fixes

The patchset was very hard to review for me, maybe because of its fixing
order?  The 2/4 patch uses PAGE_OFFSET but it is changed by 4/4 finally,
I'm not sure what is fixed and why it can be fixed by 2/4.  so it might
be easier to review if it fixes them in order like:
  1) fix for PAGE_OFFSET issue on 5.4 and later
  2) fix for physvirt_offset loss on 5.10 and later.

But you don't have to rewrite it, just an idea.

And as you know, I cannot test arm64 crash, please let me know about
things I missed.

Thanks,
Kazu
