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.
