This series originate from two independent bugs. Since they are closely related
to arm64 memory layout changes, finally I organize them in a batch.

This series can play with vmcore and kcore on RHEL9 (kernel v5.12, v5.13-rc).
Without it, the crash-utility fails. For compatibility, RHEL-8.5 can work
fine with this series (kernel v4.18)
