Now PowerPC Linux kernel supports hot-add to NUMA nodes not populated
initially with memory we can enable such support in qemu. This requires
two changes:
o Add device tree property "ibm,max-associativity-domains" to let
guest kernel chance to find max possible NUMA node
o Revert commit b556854bd852 ("spapr: Don't allow memory hotplug to
memory less nodes") to remove check for hot-add to memory-less node.
See description messges for individual changes for more details.
v2:
- Reorder patches in series according to description above.
- Add extra coment to revert noticing return to previous behaviour for
guests without support for hot-add to empty node.
- Drop max_cpus from topology in property due to vcpu id discontiguous
allocations. Thanks to David Gibson for extra explanation.
- Rebase to current state of master branch.
