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. Signed-off-by:

Introduce a function to read the local APIC_ID. This change is in preparation for additional changes to the APICID functions that will come in a later patch. Signed-off-by:

This is to match i386. The former name was cuter, but the current is more meaningful and more general, since cpu_id can be a logical id. Signed-off-by:

After the inclusion, a lot of files needs fixing for conflicts, some of them in the headers themselves, to accomodate for both i386 and x86_64 versions. [ mingo@elte.hu: build fix ] Signed-off-by:

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:

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. Signed-off-by:

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.

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:

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:Andrew Morton <akpm@linux-foundation.org>
