SGI UV cpumask: use static temp cpumask in flush_tlb Impact: Improve tlb flush performance for UV Calling alloc_cpumask_var a zillion times a second does affect performance. Replace with static cpumask. Note: when CONFIG_X86_UV is defined, this extra PER_CPU memory will be optimized out for non-UV configs as is_uv_system() will then return a constant 0.
