Subject: [PATCH 1/2] x86, acpi: add MAX_LOCAL_APIC for 32bit
Date: Fri, 17 Dec 2010 03:09:24 +0000 [thread overview]
Message-ID: <4D0AD464.2020408@kernel.org> (raw)
In-Reply-To: <4D094703.7080701@zytor.com>
We should use MAX_LOCAL_APIC for max apic ids
and MAX_APICS as number of local apics.
also apic_version[] array should max apic id related.
