powerpc/mm: remove a couple of #ifdef CONFIG_PPC_64K_PAGES in mm/slice.c
This patch replaces a couple of #ifdef CONFIG_PPC_64K_PAGES by IS_ENABLED(CONFIG_PPC_64K_PAGES) to improve code maintainability. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
