+Subject: riscv: Replace function-like macro by static inline function
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Björn Töpel <bjorn@rivosinc.com>
+
+commit 121f34341d396b666d8a90b24768b40e08ca0d61 upstream.
+
+The flush_icache_range() function is implemented as a "function-like
+macro with unused parameters", which can result in "unused variables"
+warnings.
+
+Replace the macro with a static inline function, as advised by
+Documentation/process/coding-style.rst.
+
+Fixes: 08f051eda33b ("RISC-V: Flush I$ when making a dirty page executable")
