[PATCH 0/4] kdump : add support for ibm, dynamic-reconfiguration-memory for kexec/kdump

[Chandru]

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.
