2008-10-22x86: fix section mismatch warning - apic_x2apic_clusterMarcin Slusarz
Impact: cleanup only, no functionality changed WARNING: vmlinux.o(.data+0xbf88): Section mismatch in reference from the variable apic_x2apic_cluster to the function .init.text:x2apic_acpi_madt_oem_check() The variable apic_x2apic_cluster references the function __init x2apic_acpi_madt_oem_check() Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-08-23x86: use x2apic id reported by cpuid during topology discoverySuresh Siddha
use x2apic id reported by cpuid during topology discovery, instead of the apic id configured in the APIC. For most of the systems, x2apic id reported by cpuid leaf 0xb will be same as the physical apic id reported by the APIC_ID register of the APIC. We follow the suggested guidelines and use the apic id reported by the cpuid. No change to non-generic UV platforms, will use the apic id reported in the APIC_ID register as the cpuid reported apic id's may not be unique.

2008-07-22x86: add apic probe for genapic 64bit, v2Yinghai Lu
introducing an APIC handling probing abstraction: static struct genapic *apic_probe[] __initdata = { &apic_x2apic_uv_x, &apic_x2apic_phys, &apic_x2apic_cluster, &apic_physflat, NULL, }; This way we can remove UV, x2apic specific code from genapic_64.c and move them to their specific genapic files.

2008-07-13x86: make 64bit have get_apic_idYinghai Lu
generalize the x2apic code some more. let read_apic_id become a macro (later on a function/inline) GET_APIC_ID(apic_read(APIC_ID)) +#define read_apic_id() (GET_APIC_ID(apic_read(APIC_ID))) instead of this weird construct: -#define read_apic_id (genapic->read_apic_id) Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
