Merge tag 'riscv/for-v5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

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"
