Bibo Mao 2292d9691c hugetlb: clear huge pte during flush function on mips platform ... [ Upstream commit 33ae8f801a ] If multiple threads are accessing the same huge page at the same time, hugetlb_cow will be called if one thread write the COW huge page. And function huge_ptep_clear_flush is called to notify other threads to clear the huge pte tlb entry. The other threads clear the huge pte tlb entry and reload it from page table, the reload huge pte entry may be old. This patch fixes this issue on mips platform, and it clears huge pte entry before notifying other threads to flush current huge page entry, it is similar with other architectures.
