No patches posted yet, but hopefully soon. These bits will likely be added as part of an effort that moves all memory hotplug/unplug into guest kernel instead of relying on drmgr. Most of the bits for in-kernel memory hotplug are already upstream, but there's a number of other requirements in the spec update (like a new hotplug interrupt/queue instead of re-using EPOW) that need to be addressed as part of the switchover. > > Thomas >
