Christoph Muellner <christoph.muellner@vrull.eu> says: From: Christoph Müllner <christoph.muellner@vrull.eu> When building the RISC-V selftests with a riscv32 compiler I ran into a couple of compiler warnings. While riscv32 support for these tests is questionable, the fixes are so trivial that it is probably best to simply apply them. Note that the missing-include patch and some format string warnings are also relevant for riscv64. * b4-shazam-merge: tools: selftests: riscv: Fix compile warnings in mm tests tools: selftests: riscv: Fix compile warnings in vector tests tools: selftests: riscv: Add missing include for vector test tools: selftests: riscv: Fix compile warnings in cbo tools: selftests: riscv: Fix compile warnings in hwprobe Link: https://lore.kernel.org/r/20231123185821.2272504-1-christoph.muellner@vrull.eu Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
