I Recently noticed the Patch Queue Review meeting, and as mentioned in 
the previous notes, I am confused about the mean of RISCV maintainers 
are working on this. Does it mean that the RVV support provided by 
machine maintainers will come soon? Before that, any patches on RVV 
support will not be accepted?
