* x86: rename all fields of mpc_table mpc_X to XJaswinder Singh Rajput2009-01-05
| | | | | | | | | | | | Impact: cleanup, solve 80 columns wrap problems It would be cleaner to rename all the mpc->mpc_X fields to mpc->X - that alone would give 4 characters per usage site.

| | * x86: fix cpu_mask_to_apicid_and to include cpu_online_maskMike Travis2008-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

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.

This patch makes sure that the gfn will be unaliased and add gfn_to_memslot_unaliased() to save the calculating of the gfn unaliasing in case we have it unaliased already.

Only if the counter > 0, we push the PIT ticks via all LAPIC LVT0 lines to enable NMI watchdog support.
