Subject: [PATCH v3 13/16] kvm: lapic: Clean up APIC predefined macros
Date: Fri, 13 Sep 2019 19:01:07 +0000 [thread overview]
Message-ID: <1568401242-260374-14-git-send-email-suravee.suthikulpanit@amd.com> (raw)
In-Reply-To: <1568401242-260374-1-git-send-email-suravee.suthikulpanit@amd.com>
Move these duplicated predefined macros to the header file so that
it can be re-used in other places.
