+You can use SPFLAGS to add debugging flags, for instance you may want to
+add both --profile --show-trying to SPFLAGS when debugging. For instance
+you may want to use:
+
+    rm -f err.log
+    export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci
+    make coccicheck DEBUG_FILE="err.log" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd/arizona-irq.c
+
+err.log will now have the profiling information, while stdout will
+provide some progress information as Coccinelle moves forward with
+work.
+
 DEBUG_FILE support is only supported when using coccinelle >= 1.2.
