If you run checkpatch.pl on this patch: http://patchwork.ozlabs.org/patch/84189/
it complains:
WARNING: braces {} are necessary even for single statement blocks
#29: FILE: tcg/tcg.c:454:
+#if defined(CONFIG_DEBUG_TCG)
+ s->temps_in_use++;
...but braces on a cpp conditional are a bit tricky :-)
The script is sufficiently hairy perl that I'm afraid I
can't suggest a solution, only report the problem.
