Devices hot plugging support.
The hotplug pseudo-device passes device attachment and detachment events
to userland. When a device attaches or detaches, the corresponding event
is queued. The events can then be obtained from the queue through the
read(2) call on the /dev/hotplug device file. Each event consists of
event type (attach/detach), device class (DV_*) and device name (sd1 e.g.).
We have hotplug pseudo-device on alpha, amd64, i386, macppc and sparc64.
Since it was tested only on i386 other archs has it commented out
in GENERIC until tested.
The idea liked peter@ tedu@ drahn@ millert@ marco@ henning@.
Ok deraadt@.
