[PATCH] dma/fence: Export enable-signaling tracepoint for emission by drivers

[PATCH] dma/fence: Export enable-signaling tracepoint for emission by drivers

[Chris Wilson]

Currently this tracepoint is solely used by dma_fence_enable_sw_signaling,
however I have a need to manually perform the hw enabling of the
signaling and would like to emit this tracepoint for completeness.
