/proc/device-tree on power6 machines has ibm,dynamic-reconfiguration-memory 
node which stores in it the memory representation for most part of the system 
memory. This memory was earlier represented in 'memory@' nodes of the device 
tree.  Following patch series makes kexec-tools aware of this dynamic 
reconfiguration memory node. These patches were sent earlier for RFC. In 
addition to this, a change in the kernel was also required. The kernel change 
has been accepted in powerpc git tree.

Some part of the patch here is re-organization of the existing code to 
accommodate dynamic reconf memory.
