vma_mmu_pagesize() is only required for slices, otherwise there is a generic weak version doing the exact same thing. Move it to slice.c Signed-off-by: Christophe Leroy <redacted> --- arch/powerpc/mm/hugetlbpage.c | 11 ----------- arch/powerpc/mm/slice.c | 9 +++++++++ 2 files changed, 9 insertions(+), 11 deletions(-)
