Alexandre Ghiti 9d4e8d5fa7 riscv: Make __flush_tlb_range() loop over pte instead of flushing the whole tlb ... Currently, when the range to flush covers more than one page (a 4K page or a hugepage), __flush_tlb_range() flushes the whole tlb. Flushing the whole tlb comes with a greater cost than flushing a single entry so we should flush single entries up to a certain threshold so that: threshold * cost of flushing a single entry < cost of flushing the whole tlb.
