Updated variant of a patch by Joel Schopp. The field containing the number of supported cores which we pass to firmware via the ibm,client-architecture call was set by a previous patch statically as high as is possible (NR_CPUS). However, that value isn't quite right for a system that supports multiple threads per core, thus permitting the firmware to assign more cores to a Linux partition than it can really cope with. This patch improves it by using the device-tree to determine the number of threads supported by the processors in order to adjust the value passed to firmware.
