RE: \_PR\CPU\_INI not called during initialization

[Nate Lawson <nate-Y6VGUYTwhu0@public.gmane.org>]

Here is the info I'm going on, section 5.3.1:

%%%
\_PR
ACPI 1.0 Processor Namespace. ACPI 1.0 requires all Processor objects to
be defined under this namespace. ACPI 2.0 allows Processor object
definitions under the \_SB namespace. ACPI 2.0-compatible systems may
maintain the \_PR namespace for compatibility with ACPI 1.0 operating
systems. An ACPI 2.0-compatible namespace may define Processor objects in
either the \_SB or \_PR scope but not both.

\_SB
All Device/Bus Objects are defined under this namespace.
%%%

I read this to mean that in ACPI 2.0, Processor objects are devices
regardless of whether they are defined under \_SB or under \_PR.
