Merge r221846 from largeSMP project branch:

Fix arguments passing to _long() version of atomic function for mips.

The native implementation is bogus in that regard and offers the same
problem solved for powerpc as r222198, but mips' guys just wanted a
small and self-contained patch for mips rather than rewriting the
whole support.
