Pull RISC-V updates from Paul Walmsley:
"Four minor RISC-V-related changes:
- Add support for the new clone3 syscall for RV64, relying on the
generic support
- Add DT data for the gigabit Ethernet controller on the SiFive FU540
and the HiFive Unleashed board
- Update MAINTAINERS to add me to the arch/riscv maintainers' list
- Add support for PCIe message-signaled interrupts by reusing the
generic header file"
