Background: new aio code is adding __get_user() calls referencing 64
bit quantities (__u64 and __s64).  

There's lots more architectures which do not support 64-bit get_user()
_or_ __get_user(): avr32, blackfin, metag for example, and m68k which
has this interesting thing "/* case 8: disabled because gcc-4.1 has a
broken typeof \" in its *get_user() implementation.  

And if you enable it again, you get lots of "warning: cast to pointer from
integer of different size", like you mentioned.

Any thoughts?  I am still using the version of tha aio tree from
next-20160111.
