The proximal cause of the pain is that I #included <sys/mutex.h> in
<sys/device.h>. <sys/mutex.h> #includes <machine/intr.h> that, on
some systems, #includes a device driver's xxxvar.h that #includes
ISTM that the root cause of the pain is that <machine/intr.h> #includes
a driver's xxxvar.h, but that is just my interpretation.
