Rik van Riel 016c4d92cd x86/mm/tlb: Add freed_tables argument to flush_tlb_mm_range 
Add an argument to flush_tlb_mm_range to indicate whether page tables
are about to be freed after this TLB flush. This allows for an
optimization of flush_tlb_mm_range to skip CPUs in lazy TLB mode.

No functional changes.
