    Pull misc compat stuff updates from Al Viro:
     "This part is basically untangling various compat stuff. Compat
      syscalls moved to their native counterparts, getting rid of quite a
      bit of double-copying and/or set_fs() uses. A lot of field-by-field
      copyin/copyout killed off.
    
       - kernel/compat.c is much closer to containing just the
         copyin/copyout of compat structs. Not all compat syscalls are gone
         from it yet, but it's getting there.
    
       - ipc/compat_mq.c killed off completely.
    
       - block/compat_ioctl.c cleaned up; floppy compat ioctls moved to
         drivers/block/floppy.c where they belong. Yes, there are several
         drivers that implement some of the same ioctls. Some are m68k and
         one is 32bit-only pmac. drivers/block/floppy.c is the only one in
         that bunch that can be built on biarch"
