Any reasons for not putting it into drivers/acpi/pptt.c specifically?
.
I don't think so.
One thing is that the code does a one-time scan of the PPTT to find all
processor package nodes with ID structures to register the soc devices -
so we would need some new call from from acpi_init() for that.

I don't see a problem if we want to use a soc driver, but that is
starting to look unlikely.
Alternatively, if we want to create some folder under
/sys/firmware/acpi, any restriction comes from the folder location.
For a folder like /sys/firmware/acpi/pptt, we need to ensure acpi_kobj
is initialized; acpi_kobj is set from subsys_init(acpi_init), so
module_init() for pptt module would suffice.
However if we wanted to make pptt folder a sub-folder from those created
in acpi_sysfs_init() - then we would need to make that parent folder
kobj non-static. Again, module_init() would suffice.
Thanks,
John
