powerpc/mm: drop #ifdef CONFIG_MMU in is_ioremap_addr()
powerpc always selects CONFIG_MMU and CONFIG_MMU is not checked anywhere else in powerpc code. Drop the #ifdef and the alternative part of is_ioremap_addr() Fixes: 9bd3bb6703d8 ("mm/nvdimm: add is_ioremap_addr and use that to check ioremap address") Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/de395e444fb8dd7a6365c3314d78e15ebb3d7d1b.1566382245.git.christophe.leroy@c-s.fr
