Leonid Yegoshin b0e2e3acfe MIPS: R2-on-R6 MULTU/MADDU/MSUBU emulation bugfix 
commit d65e5677ad5b3a49c43f60ec07644dc1f87bbd2e upstream.

MIPS instructions MULTU, MADDU and MSUBU emulation requires registers HI/LO
to be converted to signed 32bits before 64bit sign extension on MIPS64.

Bug was found on running MIPS32 R2 test application on MIPS64 R6 kernel.

Fixes: b0a668fb2038 ("MIPS: kernel: mips-r2-to-r6-emul: Add R2 emulator for MIPS R6")
