It seems that cpu_path and cpu_bus_path in include/device/path.h are not
So what do you prefer
unsigned node id;

Stepan: No, the information has to be reorganized. Currently pirq and
Stepan: have to be hand crafted, and this is the complicated thing.
Stepan: abstract information should be put to the configuration filess,
Stepan: can not be probed.
YH: I suggest to add
1. one node id to ram_resource, so the index will be (idx<<8 | nodeid),
So I can re-use ram_resource in pci_domain for SRAT creating.
2. for apci_cluster_id, will add two fields core_id and node_id, (
instantiate it when cpu_init)...
3. pci device: add pci_irq_routing, and pci_possiable_resource ( for
apci _PRT and _PRS...)
how about ioapci in the internal tree?
