From 4650d02ad2d9b2c1c7aa36055166db6aee68f72e Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Tue, 14 Nov 2017 11:35:37 -0800 Subject: [PATCH] RISC-V: Remove unused arguments from ATOMIC_OP Our atomics are generated from a complicated series of preprocessor macros, each of which is slightly different from the last. When writing the macros I'd accidentally left some unused arguments floating around. This patch removes the unused macro arguments.
