Impact: cleanup, reduce kernel size a bit, avoid sparse warnings Fixes sparse warnings: arch/x86/kernel/genx2apic_phys.c:164:6: warning: symbol 'x2apic_send_IPI_self' was not declared. Should it be static? arch/x86/kernel/genx2apic_phys.c:169:6: warning: symbol 'init_x2apic_ldr' was not declared. Should it be static?

Impact: fix potential APIC crash In determining the destination apicid, there are usually three cpumasks that are considered: the incoming cpumask arg, cfg->domain and the cpu_online_mask. Since we are just introducing the cpu_mask_to_apicid_and function, make sure it includes the cpu_online_mask in it's evaluation. [Added with this patch.] There are two io_apic.c functions that did not previously use the cpu_online_mask: setup_IO_APIC_irq and msi_compose_msg. Both of these simply used cpu_mask_to_apicid(cfg->domain & TARGET_CPUS), and all but one arch (NUMAQ[*]) returns only online cpus in the TARGET_CPUS mask, so the behavior is identical for all cases. [*: NUMAQ bug?] Note that alloc_cpumask_var is only used for the 32-bit cases where it's highly likely that the cpumask set size will be small and therefore CPUMASK_OFFSTACK=n. But if that's not the case, failing the allocate will cause the same return value as the default. Signed-off-by: NMike Travis <travis@sgi.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

Impact: new API Add a helper function that takes two cpumask's, and's them and then returns the apicid of the result. This removes a need in io_apic.c that uses a temporary cpumask to hold (mask & cfg->domain). Signed-off-by: NMike Travis <travis@sgi.com> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

Impact: cleanup, change parameter passing * Change genapic interfaces to accept cpumask_t pointers where possible. * Modify external callers to use cpumask_t pointers in function calls. * Create new send_IPI_mask_allbutself which is the same as the send_IPI_mask functions but removes smp_processor_id() from list. This removes another common need for a temporary cpumask_t variable. * Functions that used a temp cpumask_t variable for: cpumask_t allbutme = cpu_online_map; cpu_clear(smp_processor_id(), allbutme); if (!cpus_empty(allbutme)) ... become: if (!cpus_equal(cpu_online_map, cpumask_of_cpu(cpu))) ... * Other minor code optimizations (like using cpus_clear instead of CPU_MASK_NONE, etc.) Applies to linux-2.6.tip/master.

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.

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.
