Subject: [PATCH v4 14/17] kvm: lapic: Clean up APIC predefined macros
Date: Fri, 1 Nov 2019 22:41:39 +0000	[thread overview]
Message-ID: <1572648072-84536-15-git-send-email-suravee.suthikulpanit@amd.com> (raw)
In-Reply-To: <1572648072-84536-1-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.
