We see *lots* of new warnings in RISC-V with Clang 17. Here's one:
-----8<----- /builds/linux/mm/oom_kill.c:1195:1: warning: unused function '___se_sys_process_mrelease' [-Wunused-function] 1195 | SYSCALL_DEFINE2(process_mrelease, int, pidfd, unsigned int, flags) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /builds/linux/include/linux/syscalls.h:221:36: note: expanded from macro 'SYSCALL_DEFINE2' 221 | #define SYSCALL_DEFINE2(name, ...)

riscv: Fix syscall wrapper for >word-size arguments
[ Upstream commit a9ad73295cc1e3af0253eee7d08943b2419444c4 ]
Reverting that patch makes the (300+) warnings disappear.
Reproducer:
tuxmake --runtime podman --target-arch riscv --toolchain clang-17 --kconfig allnoconfig --kconfig-add rv32_defconfig LLVM=1
