Subject: [kernel 3.13.0-06058-g2d08cd0] Strange ACPI error messages

Kernel 3.13.0-06058-g2d08cd0 displays following errors on the console:

ACPI: \_PR_.CPU4: failed to get CPU APIC ID.
ACPI: \_PR_.CPU5: failed to get CPU APIC ID.
ACPI: \_PR_.CPU6: failed to get CPU APIC ID.
ACPI: \_PR_.CPU7: failed to get CPU APIC ID.

I don't have CPUs 4..7! Error messages regarding not existing
CPUs should not be displayed.
kernel 3.13.0-05617-g3aacd62 and before did'nt show this messages.

This is a regression. I never saw this messages before.

Processor model: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
$ cat /proc/cpuinfo | grep processor
processor       : 0
processor       : 1
processor       : 2
processor       : 3
