Some architectures set and maintain the mm_cpumask bits when loading
or removing process from cpu.
This Kconfig will mark those to allow different behavior between
kernels that maintain the mm_cpumask and those that do not.

to differentiate architectures that support mm_cpumask from
those that don't will allow safe usage of this feature.
Yair Podemsky (3):
arch: Introduce ARCH_HAS_CPUMASK_BITS
mm/mmu_gather: send tlb_remove_table_smp_sync IPI only to MM CPUs
mm/mmu_gather: send tlb_remove_table_smp_sync IPI only
the mask used should be
cpu_online_mask (Peter Zijlstra).
