I assume this is 512M?

Hi,
I am seeing a problem with the kdump kernel running on my Freescale mpc8536
based board.
Specifically when the crash kernel boots after a forced panic, vmcore fails to
initialize.
The following errors are displayed by vmcore_init()
Warning: Core image elf header not found
Kdump: vmcore not

This patch implements the crash_map_pages() function for s390.
KEXEC_CRASH_MEM_ALIGN is set to HPAGE_SIZE, in order to support
kernel mappings that use large pages.

Hello Vivek, Andrew, Martin
Here the updated patch series for the removal of page tables for the
crashkernel memory:
[1] kdump: Add infrastructure for unmapping crashkernel memory
[2] s390: Add architecture code for unmapping crashkernel memory
The patches apply on top of the last kdump patch se
From: Michael Holzheu
This patch introduces a mechanism that allows architecture backends to
remove page tables for the crashkernel memory. This can protect the loaded
kdump kernel from being overwritten by broken kernel code. Two new
functions crash_map_reserved_pages() and crash_unmap_reserved

Yup. I am working on it, will post the patches very soon.
