Following is a patch series that contains changes for kexec/kdump on Power6
machines. Power6 machines have most of their memory represented
in /proc/device-tree/ibm,dynamic-reconfiguration-memory node. kexec-tools
currently read only memory@ nodes of device-tree. Patch 1/4 contains changes
in the kernel. Patch {2,3,4}/4 are changes for kexec-tools. The kernel
changes are similar to what was earlier present for memory@ nodes
for 'linux,usable-memory' property. Unlike memory@ nodes, since now there is
one node under which most of the memory ranges are represented (
ibm,dynamic-memory) , I have appended the lmb entry number to
the 'linux,usable-memory' string so as to identify usable-memory ranges in
the device-tree.
