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