Ed Maste a0cd78bf2c kbd: replace vestigial spl calls with Giant assertions ... The keyboard driver was initially protected via spl* interrupt priority calls but (as part of a comprehensive effort) migrated to use the Giant lock (mutex). The spl calls left behind became NOPs but they can be confusing as they have no bearing on the actual mutual exclusion that is now present. Remove them from kbd and add assertions that Giant is held. markj notes that there is conflation between the "bus topo" lock (which is Giant under the hood) and Giant. The assertions could either be addressed as a small item along with bus topology locking work or they'll be removed if kbd is decoupled from Giant.
