Excellent.

Yunqiang, for the record is this mips64 or mips64r2?  If mips64r2, it might be
helpful to re-test with use_mips32r2_instructions forced to 0 in
tcg_target_detect_isa, since there are different paths selected based on that.

Excellent, thanks.

Ok, I guess we will just have to drop the R6 patches for now, until imgtec is
able to provide feedback on them.
