[PATCH -next] m68k/m68knommu: Implement __get_user_unaligned/__put_user_unaligned()

[Geert Uytterhoeven]

fs/btrfs/ioctl.c:2802: error: implicit declaration of function â__put_user_unalignedâ

Btrfs is the first user of __put_user_unaligned() outside the compat code,
hence now all 32-bit architectures should make sure to implement this, too.
