From e0da33646826b66ef933d47ea2fb7a693fd849bf Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 8 Jun 2008 18:29:22 -0700 Subject: x86: introduce max_physical_apicid for bigsmp switching a multi-socket test-system with 3 or 4 ioapics, when 4 dualcore cpus or 2 quadcore cpus installed, needs to switch to bigsmp or physflat. CPU apic id is [4,11] instead of [0,7], and we need to check max apic id instead of cpu numbers. also add check for 32 bit when acpi is not compiled in or acpi=off.
