[Xen-devel] [PATCH] xen/cpuidle: Reduce logging level for unknown apic_ids

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Dom0 uses this hypercall to pass ACPI information to Xen.

It is not very uncommon for more cpus to be listed in the ACPI tables than are
present on the system, particularly on systems with a common BIOS for a 2 and
4 socket server varients.

As Dom0 does not control the number of entries in the ACPI tables, and is
required to pass everything it finds to Xen, reduce the ERR to an INFO.
