2008-04-17x86: increase size of APICIDJack Steiner
Increase the number of bits in an apicid from 8 to 32. By default, MP_processor_info() gets the APICID from the mpc_config_processor structure. However, this structure limits the size of APICID to 8 bits. This patch allows the caller of MP_processor_info() to optionally pass a larger APICID that will be used instead of the one in the mpc_config_processor struct.

2008-04-17x86: change boot_cpu_id to boot_cpu_physical_apicidGlauber de Oliveira Costa

2008-04-17x86: get boot_cpu_id as early for k8_scan_nodesYinghai Lu
When acpi=off or there is no SRAT defined, apicid_to_node is got from K8 Northbridge PCI configuration space in k8_scan_nodes() in arch/x86_64/mm/k8toplogy.c. The problem is that it assumes bsp apic id is 0 at that point. For four socket system with Quad core cpus installed, all cpus apic id is offset by 4, and bsp apic id is 4. For eight socket system with dual core cpus installed, all cpus apic id is offset by 2, and bsp apic id is 2. We need get boot_cpu_id --- bsp apic id, before k8_scan_nodes by called. So create early_acpi_boot_init and early_get_smp_config for get boot_cpu_id. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-01-30x86: fix section mismatch warning in acpi/boot.cSam Ravnborg
Fix following warning: WARNING: arch/x86/kernel/built-in.o(.text+0x10ea0): Section mismatch: reference to .cpuinit.data:num_processors in 'acpi_unmap_lsapic' The exported function acpi_unmap_lsapic() references the variable num_processors that is annotated __cpuinitdata. Remove the annotation of num_processors as we never know when an exported function are called. And drop the needless initialsation to 0. Warning was seen on 64 bit but similar pattern were seen in 32 bit - so fix it up there too.

2008-01-30x86: change bios_cpu_apicid to percpu data variabletravis@sgi.com
Change static bios_cpu_apicid array to a per_cpu data variable. This includes using a static array used during initialization similar to the way x86_cpu_to_apicid[] is handled. There is one early use of bios_cpu_apicid in apic_is_clustered_box(). The other reference in cpu_present_to_apicid() is called after smp_set_apicids() has setup the percpu version of bios_cpu_apicid.

2008-01-30x86: change size of APICIDs from u8 to u16travis@sgi.com
Change the size of APICIDs from u8 to u16. This partially supports the new x2apic mode that will be present on future processor chips. (Chips actually support 32-bit APICIDs, but that change is more intrusive. Supporting 16-bit is sufficient for now). Signed-off-by: Jack Steiner <steiner@sgi.com> I've included just the partial change from u8 to u16 apicids. The remaining x2apic changes will be in a separate patch. In addition, the fake_node_to_pxm_map[] and fake_apicid_to_node[] tables have been moved from local data to the __initdata section reducing stack pressure when MAX_NUMNODES and MAX_LOCAL_APIC are increased in size.

2007-10-19x86: acpi use cpu_physical_idMike Travis
This is from an earlier message from Christoph Lameter: processor_core.c currently tries to determine the apicid by special casing for IA64 and x86. The desired information is readily available via cpu_physical_id() on IA64, i386 and x86_64. Signed-off-by: Christoph Lameter <clameter@sgi.com> Additionally, boot_cpu_id needed to be exported to fix compile errors in dma code when !CONFIG_SMP.

2007-10-19x86: convert cpu_to_apicid to be a per cpu variableMike Travis
This patch converts the x86_cpu_to_apicid array to be a per cpu variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions. MP_processor_info() is one of the functions that require access to the x86_cpu_to_apicid array before the per_cpu data area is setup. For this case, a pointer to the __initdata array is initialized in setup_arch() and removed in smp_prepare_cpus() after the per_cpu data area is initialized. A second change is included to change the initial array value of ARCH i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.
