Subject[patch 29/46] ACPI: fix missing include for UP
From: Thomas Gleixner <>

apic.h does not get included on UP compiles. That way the
APICTIMER_STOPS_ON_C3 is not there and UP boxen have no support for
timer broadcasting. This was never noticed, because the lapic timer is
only used for profiling on UP.
