Things dealing with libstdc++-v3 should also be sent to that list.
I'll leave the guts of the patch to a MIPS maintainer to approve, but here
are some things you'll need to change:

> + _Atomic_word __result, __tmp, temp;
The name must have two leading underscores, so it would have to be __temp,
not temp. Likewise for the second function.
Please consider renaming these to something more descriptive. We know
they're temporary. :-) We don't know what they're used for without
studying the assembly. (Feel free to rename tmp as well.)

Watch the extra space in the first line. (Might as well get the cosmetic
aspects right from the beginning.)
