Do we have code using acpi_subtable_proce.count?
I think the answer is yes because of:
[Patch] x86, ACPI: Fix the wrong assignment when Handle apic/x2apic entries

So why don't you put these 2 patches together into a single series?
And help to validate if there are problems in other acpi_subtable_proce.count users.

Thanks
