[PATCH] arc: include: asm: uaccess.h: include "asm-generic/uaccess-unaligned.h"

[Chen Gang]

Need include the default implementation, just like another platforms
(e.g. parisc, tile ...), or can not pass compiling.

The related error (with allmodconfig for arc):

    CC [M]  fs/btrfs/ioctl.o
  fs/btrfs/ioctl.c: In function ‘btrfs_ioctl_file_extent_same’:
  fs/btrfs/ioctl.c:2802: error: implicit declaration of function ‘__put_user_unaligned’
