Impact: use new cpumask API to reduce memory usage This is part of an effort to reduce structure sizes for machines configured with large NR_CPUS. cpumask_t gets replaced by cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or struct cpumask * (large NR_CPUS).

Impact: use new cpumask API to reduce memory and stack usage Allocate the following local cpumasks based on the number of cpus that are present. References will use new cpumask API. (Currently only modified for x86_64, x86_32 continues to use the *_map variants.) cpu_callin_mask cpu_callout_mask cpu_initialized_mask cpu_sibling_setup_mask Provide the following accessor functions: struct cpumask *cpu_sibling_mask(int cpu) struct cpumask *cpu_core_mask(int cpu) Other changes are when setting or clearing the cpu online, possible or present maps, use the accessor functions.

Impact: Reduce future system panics due to cpumask operations using NR_CPUS Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are allocated based on nr_cpu_ids, these extra bits will not be defined. Also some other minor updates: * change in to use cpu accessor function set_cpu_present() instead of directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c] * use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c] * optimize some cpu_mask_to_apicid_and functions.
