Subject: [PATCH] ACPI: fix missing include for UP
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3434933b17fa64adddf83059603c61296f6e1ee2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] ACPI: fix missing include for UP

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.
