Log message:
The "USL" VT switch and keyboard ioctls are a hack and don't follow the
proper BSD way where the third argument is always a pointer and data is
transferred between userland and kernel using copyin(9) and copyout(9).
Intead an int is encoded in the thirs argument. This works on 32-bit
architectures and little-endian 64-bit architectures. But not on
big-endian 64-bit architectures. Deal with this by handling the argument
as long (which matches the size of a pointer).
Hopefully we can eliminate these ioctls in the near future.
