set_huge_pte_at() expects the size of the hugepage as an int, not the psize which is the index of the page definition in table mmu_psize_defs[] Fixes: 935d4f0c6dc8 ("mm: hugetlb: add huge page size param to set_huge_pte_at()") Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> --- arch/powerpc/mm/nohash/8xx.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
