It seems the patch 39148e94e3e1f0477ce8ed3fda00123722681f3a
"MIPS: fork: Fix MSA/FPU/DSP context duplication race"
assumes that DSP/FPU and MSA context should be inherited in child at clone/fork
(look into patch description). It was done on Matthew Fortune request from
toolchain team, I guess.
Well, in this case it should prevent clearing TIF_MSA_CTX_LIVE in copy_thread().
