[Yinghai Lu - Fri, May 01, 2009 at 09:48:34PM -0700] | | Ed found that on 32bit, boot_cpu_physical_apicid is not read right, | when mptable is broken. | | interesting, actually three path | 1. acpi: at that time, at that time that is already read from reg. | 2. mptable: that only read from mptable. | 3. no madt, and no mptable, that use default apic id 0 for 64bit, -1 for 32bit | | so could read that apic id for 2/3 path. | | also could avoid set fixmap that lapic two times when acpi_lapic is used. | and need to move cpu_has_apic earlier and call apic_disable() | | Reported-by: Ed Swierk <eswierk@aristanetworks.com> | Signed-off-by: Yinghai Lu <yinghai@kernel.org> | Cc: Cyrill Gorcunov <gorcunov@openvz.org> |
Thanks Yinghai! My Ack if needed.
