Include ath in my kernel builds now that I need it.
Merge branch 'master' into markj-kernel-config
Add a module unload hook for SDT; we want to be able to deregister a
provider when all of its probes have gone away as the result of a module
unload. However, we can't do that in the probe destroy method since we
already hold the provider lock.
Make sure that we don't create probes with whitespace in their names.
Merge branch 'markj-kernel-config' into 20130624-sdt-module-info
Add a new malloc type for SDT and get rid of an unsed macro.
Try using dtrace_condense to clean up probes before unloading a module.
