Can you please also share git tree path of corresponding kexec-tools changes?

Could it be a better idea (if things in user space become simpler)
that in stead of patch 5 and 6, we pass arch_phys_to_idmap_offset to
user space, and then user space manipulates existing "Crash kernel"
and "System RAM" resources.
