Log Message:
DTrace: Add the Function Boundary Trace (FBT) provider moduile. This
module instruments every function in the kernel with entry and exit
probes. These probes are true zero-effect probes in that they don't
exist in the code until they are enabled. The probes are enabled by
directly patching the function entry and exit points to make jumps into
the dtrace framework.
This gives us over 29,000 trace points in the kernel.
