As an explanation, the removal of add_event_entry is the whole point
of this patch. add_event_entry must only be called with buffer_mutex
held, but buffer_mutex itself is not exported.
I'm pretty sure that no other user of add_event_entry exists, as it
was exported specifically for the SPU support and that never worked.
Any other (theoretical) code using it would be broken in the same way
and need a corresponding fix.
We can easily leave the declaration in place, but I'd recommend removing
it eventually. If you prefer to keep it, how about marking it as
__deprecated?
