Okay, I will prepare a PR with following patchsets: 1. Fixmap support and MM cleanups (Author: Anup Patel) 2. riscv: minor fixes and cleanups (Author: Johan Hovold) 3. RISC-V related changes from "Various SMP related fixes" (Author: Atish Patra) All above patchsets touch same source files so this will help you. Regards, Anup
