I would like to provide an update on our side. Ruidong has left Alibaba and is no longer focusing on kernel development. I will be taking over the development and upstreaming of the arm64 ARCH_HAS_COPY_MC series, building on Tiangen's and Ruidong's work. This work is already underway. I will follow up on the feedback from previous revisions and plan to submit an updated series in the near future. I have also added my colleagues Shuai Xue and Baolin Wang to Cc. Please keep me copied on further discussions of this series. Any additional guidance on outstanding issues or priorities for the next revision would be appreciated. Best regards, Weilin
