Hi, These are the patches that are required to support CPU hotplug for sPAPR guests. Until now these patches were carried as part of the combined patchset for sPAPR CPU and Memory hotplug. Since some of these patches are well reviewed and can be included before the core hotplug changes, I am posting them as a separate series.
The last post of these patches were with the combined series version 3. https://lists.nongnu.org/archive/html/qemu-devel/2015-04/msg02910.html This split-out series starts with v4 which has the following minor changes: - Using maxram_size from MachineState instead of sPAPREnvironment. (2/8) - Added a patch to walk CPUs list in reverse order. (3/8) - Walking CPUs list in reverse order to ensure CPU device tree entries are filled up in proper order in device tree. (4/8) - Use of MSR_EP define instead of using direct number. (5/8) - Don't set irq for those CPUs that are already removed during XICS reset. (8/8) - Removed David Gibson's SoB from some patches as there were some minor changes in them. This series applies against spapr-next branch of David Gibson's tree.
