Subject: [RFC Patch V2 04/16] ACPI: Make map_mat_entry handle x2apic entry
Date: Tue, 17 Jun 2014 13:29:43 +0800	[thread overview]
Message-ID: <1402982995-13747-5-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1402982995-13747-1-git-send-email-jiang.liu@linux.intel.com>

From: Yinghai Lu <yinghai@kernel.org>

Now we have map_madt_entry/MADT to handle x2apic, but does not do
that with map_mat_entry _MAT.

For hotplug on system with x2apic only support, we need to add
support for x2apic map in _MAT.
