>     kexec/kdump: RMO region does not exist in drconf memory

>     The RMO region can only exist in '/memory@0' node in the device tree.
>     While adding support for '/ibm,dynamic-reconfiguration-memory' in
>     kexec-tools, I incorrectly extended the code of '/memory@' nodes to
>     drconf memory with the assumption that what applies to '/memory@'

>     
>     With this code in place, kexec on kexec fails. The first kexec
>     works because '/memory@0' node is read after drconf memory and
>     that correctly sets rmo_base and rmo_top from '/memory@0' node.
>     While in the kexec'ed kernel, '/ibm,dynamic-reconfiguration-memory'
>     is read after '/memory@xxx' nodes and this incorrectly sets both

>     
>     x86_64 specific support, including crash memory range and purgatory setup.
>     Corresponding kernel support has been merged already.
>     
>     Together with the kexec jump features in Linux kernel, kexec jump can
>     be used for following:
>     
>     - A simple hibernation implementation without ACPI support. You can
>       kexec a hibernating kernel, save the memory image of original system
>       and shutdown the system. When resuming, you restore the memory image
>       of original system via ordinary kexec load then jump back.
>     
>     - Kernel/system debug through making system snapshot. You can make
>       system snapshot with kexec/kdump, jump back, do some thing and make
>       another system snapshot.
>     
>     - Cooperative multi-kernel/system. With kexec jump, you can switch
>       between several kernels/systems quickly without boot process except
>       the first time. This appears like swap a whole kernel/system out/in.
>     
>     - A general method to call program in physical mode (paging turning
>       off). This can be used to invoke BIOS code under Linux.

>     This patch allows one to load a lzma compressed kernel using kexec -l.
