Benjamin LaHaise b2f680380d x86/mm/32: Add support for 64-bit __get_user() on 32-bit kernels ...

The existing __get_user() implementation does not support fetching
64-bit values on 32-bit x86.  Implement this in a way that does not
generate any incorrect warnings as cautioned by Russell King.

Test code available at:

  http://www.kvack.org/~bcrl/x86_32-get_user.tar .
