#     alpha: move __udiv_qrnnd library function to arch/alpha/lib/
#     
#     We already had the implementation for __udiv_qrnnd (unsigned divide for
#     multi-precision arithmetic) as part of the alpha math emulation code.
#     
#     But you can disable the math emulation code - even if you shouldn't -
#     and then the MPI code that actually wants this functionality (and is
#     needed by various crypto functions) will fail to build.
#     
#     So move the extended-precision divide code to be a regular library
#     function, just like all the regular division code is.  That way ie is
#     available regardless of math-emulation.
#
