+Subject: [PATCH] tools/gen_module_code: atomically rewrite the generated files
+
+The gen_module rule in rules.mk is marked as .PHONY, so make will
+execute it whenever it is mentioned. This results in gen_module_code
+being executed 64 times for a Juno build.
+
+However in heavily parallel builds there's a good chance that
+gen_module_code is writing a file whilst the compiler is reading it
+because make also doesn't know what files are generated by
+gen_module_code.
+
+The correct fix is to adjust the Makefiles so that the dependencies are
+correct but this isn't trivial, so band-aid the problem by atomically
+writing the generated files.
