The commit 08a07904e182895e1205f399465a3d622c0115b8 (v3.16-rc1) entitled "MIPS: math-emu: Remove most ifdefery": switched from build time to runtime detection for the CPU ISA level. However, along the way, a typo was introduced in the code path to return the value to the register file. Previously, the MIPSInst_FD macro was used but the above commit switched to MIPSInst_RT leading to regressions.
