On the original WaaG, split-lock was rarely triggered by WaaG kernel.
We didn't find any problems when removing this patch. So this patch
was discarded in the final patch set merge.
Now, the latest Windows graphic driver will trigger lots of
split-lock very frequently. The test team reports this patch will
affect the stability.
Add this patch back to improve stability by using a dedicate lock.
Please note: This patch is only for release 2.5 test.

When "signal_event" is called, "wait_event" will actually not block.
So it is ok to remove this line.
