[-Werror=implicit-function-declaration] 515 | return get_clear_flush(vma->vm_mm, addr, ptep, pgsize, ncontig); | ^~~~~~~~~~~~~~~ | ptep_clear_flush arch/arm64/mm/hugetlbpage.c:515:16: error: incompatible types when returning type 'int' but 'pte_t' was expected 515 | return get_clear_flush(vma->vm_mm, addr, ptep, pgsize, ncontig); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/arm64/mm/hugetlbpage.c:516:1: error: control reaches end of non-void function [-Werror=return-type] git bisect could not find the offending commit. But looking at the changes, I think its caused by: fb396bb459c1 ("arm64/hugetlb: Drop TLB flush from get_clear_flush()") which renamed get_clear_flush() to get_clear_contig(). -- Regards Sudip _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
