From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
This patch inverts the logic that distinguishes "Processor" statements
from "Device" statements, so we now check explicitly for "Processor" and
default to "Device". This removes the only real use of ACPI_PROCESSOR_HID,
so we can then remove the #define. It also has the theoretical advantage
that if a new processor _HID were ever added, we wouldn't have to change
the code here.
