Subject: arm64: perf_event: Add missing header needed for smp_processor_id()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d91cc2f46ad5bd8020902093385fedf7e9e9d755;p=linux.git

arm64: perf_event: Add missing header needed for smp_processor_id()

In perf_event.c we use smp_processor_id(), but we haven't included
<linux/smp.h> where it is defined, and rely on this being pulled in
via a transitive include. Let's make this more robust by including
<linux.smp.h> explicitly.
