The of_device_is_available() check only needs to be done once per device
node, there's no need to repeat it for each thread. Move it out of the
loop.

Right... I think it's better practice to use an explicitly sized type
where the data is directly derived from the device tree and ultimately
passed to the firmware call interface. Gradually enacting this while
tolerating some cosmetic inconsistency in the code seems OK to me, but
I'm open to other opinions.

The /proc/powerpc/ofdt interface allows the root user to freely alter
the in-kernel device tree, enabling arbitrary physical address writes
via drivers that could bind to malicious device nodes, thus making it

numa_setup_cpu can return nodes that are not online. But setup_node_data()
only initialize NODE_DATA for only online numa nodes. Hence avoid returning

That isn't compliant though? If your implementation does not have LPAR
it must set MSR[HV]=1 always.

Looks okay. Can sparse be run on arch/powerpc/boot? Would be nice to
get that working and endian annotations at some point.

Just like any other embedded platform.
Add an empty soc node.

Microwatt currently runs with MSR[HV] = 0, hence the usable-privilege
properties don't have bit 2 (for HV support) set, and we need the
/chosen/ibm,architecture-vec-5 property.
