update_mmu_tlb() can be used instead of update_mmu_cache() when the page fault handler detects that it lost the race to another page fault. It looks like this one call was missed in https://patchwork.kernel.org/project/linux-mips/patch/1590375160-6997-2-git-send-email-maobibo@xxxxxxxxxxx after Andrew asked to replace all update_mmu_cache() calls with an alias in the previous version of this patch here: https://patchwork.kernel.org/project/linux-mips/patch/1590031837-9582-2-git-send-email-maobibo@xxxxxxxxxxx/#23374625 Signed-off-by: Michel Lespinasse <michel@xxxxxxxxxxxxxx> --- mm/memory.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/memory.c b/mm/memory.c index c125c4969913..cd9432df3a27 100644 --- a/mm/memory.c +++ b/mm/memory.c @@ -3799,7 +3799,7 @@ static vm_fault_t do_anonymous_page(struct vm_fault *vmf) vmf->pte = pte_offset_map_lock(vma->vm_mm, vmf->pmd, vmf->address, &vmf->ptl); if (!pte_none(*vmf->pte)) { - update_mmu_cache(vma, vmf->address, vmf->pte); + update_mmu_tlb(vma, vmf->address, vmf->pte); goto release; } -- 2.20.1
