Looking through the tarball that was provided via this bugzilla, it looks to me like the xvnegsp fix was not included.

The functional fix for xvnegsp would need to be pulled in. this is upstream commit:

PPC64, add support for the xvnegsp instruction. Add test case for the instruction.

Also recommend the testcase output checking changes, which is upstream commit:
