2008-08-21x86: fix apic version warningYinghai Lu
after following patch, commit 1b313f4a6d7bee7b2c034b3f1e203bc360a71cca Author: Cyrill Gorcunov <gorcunov@gmail.com> Date: Mon Aug 18 20:45:57 2008 +0400 x86: apic - generic_processor_info - use physid_set instead of phys_cpu and physids_or - set phys_cpu_present_map bit AFTER check for allowed number of processors - add checking for APIC valid version in 64bit mode (mostly not needed but added for merging purpose) - add apic_version definition for 64bit mode which is used now we are getting warning for acpi path on 64 bit system. make the 64-bit side fill in apic_version[] as well.

2008-07-22x86: consolidate header guardsVegard Nossum
This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>

2008-07-08x86: fix stack overflow for large values of MAX_APICSJack Steiner
physid_mask_of_physid() causes a huge stack (12k) to be created if the number of APICS is large. Replace physid_mask_of_physid() with a new function that does not create large stacks. This is a problem only on large x86_64 systems. this paves the way to increase MAX_APICS.

2008-07-08x86: update mptable fix with no ioapic v2Yinghai Lu
if the system doesn't have ioapic, we don't need to store entries for mptable update also let mp_config_acpi_gsi not call func in mpparse so later could decouple mpparse with acpi more easily Reported-by: Daniel Exner <dex@dragonslave.de> Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Daniel Exner <dex@dragonslave.de> Cc: Len Brown <lenb@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-08x86: keep MP_intsrc_info untouched if we do not update mptableYinghai Lu
Daniel Exner reported IO-APIC enumeration breakage in linux-next. Alexey Starikovskiy found out that it might be related to commit 2944e16b25 "x86: update mptable". use enable_update_mptable to decide if need check before add mp_irqs array.

2008-06-10x86: make generic arch support NUMAQYinghai Lu
... so it could fall back to normal numa and we'd reduce the impact of the NUMAQ subarch. NUMAQ depends on GENERICARCH also decouple genericarch numa from acpi. also make it fall back to bigsmp if apicid > 8.

2008-06-10x86: introduce max_physical_apicid for bigsmp switchingYinghai Lu
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.

2008-06-03x86: update mptableYinghai Lu
make mptable to be consistent with acpi routing, so we could: 1. kexec kernel with acpi=off 2. work around BIOSes where acpi routing is working, but mptable is not right, so can use kernel/kexec to start other OSes that don't have good acpi support. command line: update_mptable Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

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: 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>
