The following patchset corrects a couple of issues with memory dlpar and adds support for the new memory layout in the device tree on the latest Power hardware and kernels.
On newer hardware and kernels, the device tree has changed so that all memory appears under the node ibm,dynamic-reconfiguration-memory. This node has several properties that describe lmbs, lmb-size and numa affinity. The ibm,dynamic-memory property is a list of all possible lmbs, where each list entry contains the base address, drc index, associativity array index and a set of flags. The ibm,associativity-lookup-arrays property contains a list of associativity arrays and the ibm,lmb-size contains the size of the lmbs For reference, memory was previously represented with a node, of the form [EMAIL PROTECTED], for each lmb assigned the system. Each of these memory nodes had properties such as ibm,my-drc-index for the drc index and regs for the base address and lmb size. With the new device tree layout, code associated with memory dlpar needs to be updated to parse the new device tree layout and properly call the memory hotplug notifier chains. Additionally, the numa associativity roiutine called during hotplug add of memory needs a seperate version for parsing the new device tree layout.
