evdev broken

Hey All,

It looks like evdev support in the kernel is broken.
sys/dev/kbdmux/kbdmux.c contains various unresolved symbols to
different evdev-related symbols.

I have the following options in my kernel config:

options         EVDEV_SUPPORT
options         EVDEV_DEBUG
options         UINPUT_DEBUG

Here's the build failure log:
