It can be set for a non-leaf entry, I assumed it would always be set for a leaf.
Is anyone doing this with a PPTT table?

QDF2400 takes a strict interpretation of the spec, and does not set the flag
for leaf nodes.  I believe there are other implementations which do set the
flag for leaf nodes.

IIRC, based on the discussions when this was added, the ACPI Processor
ID  *must be* valid for the lead nodes.T he flag bit corresponding
to that should be considered as don't care as it's always guaranteed
to be valid.

Correct.
