[RFC PATCH v5 7/8] mm: tlb: Pass struct mmu_gather to flush_tlb_range

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A few new fields were added to mmu_gather to make TLB flush smarter for
huge page by telling what level of page table is changed. However, we
can not get these infomations in flush_tlb_range() now.

This patch passes struct mmu_gather to flush_tlb_range interface, and
arm64 and power9 can all benefit from this.
