The ChangeLog entry is not the same as the commit message.

A detailed explanation should become the body of the commit message for your patch.

If there is a release out for RISC-V alrady, then this needs a bug number.

So a meaningful, but minimal commit message would be:
~~~
rsicv: Fix fmax/fmin sNaN issues (Bug XXXXX)

If any input to these functions is a sNaN then the result
should be sNaN, regardless of the input.

See discussions:
https://www.sourceware.org/ml/libc-alpha/2018-02/msg00529.html
~~~

Which is fine.

You also have assumed consensus as a machine maintainer :-)
