c4177479 "spapr: make sure RMA is in first mode of first memory node"
introduced regression which prevents from running guests with memoryless
NUMA node#0 which may happen on real POWER8 boxes and which would make
sense to debug in QEMU.
This patchset aim is to fix that and also fix various code problems in
memory nodes generation.
These 2 patches could be merged (the resulting patch looks rather ugly):
spapr: Use DT memory node rendering helper for other nodes
spapr: Move DT memory node rendering to a helper
Changes:
v2:
* minor cosmetic change in spapr_node0_size()
* spapr_populate_memory() fixed to work in a no-numa config
* patch changing max numa nodes is removed
Please comment. Thanks!
