IIRC the address space extension wasn't that complex change and I would expect
that the kexec works out of the box. It is different with 64-bit ARM which is
regarded as a completely different arch (last time I checked) in the Linux
kernel world.

Good to know. I started the ARM port only when the kernel kexec/kdump support
was working and only added the live dump support in the last minute before we
submitted the ARM patches to you :)
