Description of problem:
Kdump tests of below aarch64 baremetal models failed:

• https://beaker.engineering.redhat.com/recipes/13219212 (hpe-apache)
• https://beaker.engineering.redhat.com/recipes/13219142 (ampere-mtjade)
  Both were running into OOM after triggering panic.

Version-Release number of selected component (if applicable):
kernel-64k-5.14.0-228.dd64kv4.el9
(https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=49980272)
kexec-tools-2.0.25-10.el9
crash-8.0.2-1.el9
RHEL-9.2.0-20230110.5

How reproducible:
Always

Steps to Reproduce:
1. install and active kernel-64k-5.14.0-228.dd64kv4.el9 as the default grub entry

1. yum install -y kernel-64k-5.14.0-228.dd64kv4.el9; grubby --set-default=/boot/vmlinuz-5.14.0-228.dd64kv4.el9.aarch64+64k
   2. turn off swap device
2. sed -i '/swap/s/^/#/g' /etc/fstab;
   3. reboot into the 64k kernel and turn on the swap again.
3. sed -i '/swap/s/#//g' /etc/fstab; swapon -fav; swapoff -av; swapon -av;
4. getconf PAGESIZE
   4. trigger panic

Actual results:
after kernel-64k panic, kdump will running into OOM:
