struct drive:

  Workaround size mismatch in struct drive on alpha platform only.
  This struct is shared between kernel and userland and contains a
  dev_t, which now refers to a completely different structure in
  userland and kernel: int the kernel, userland dev_t is called
  udev_t, and dev_t is struct specinfo *.  In practical terms, kernel
  dev_t is a pointer and userland dev_t is an int, which on the alpha
  are different sizes.

  As stated, this is a workaround.  The correct fix would be in two
  parts:

  1.  Don't define structures in the kernel with the same name and a
      different content as a userland structure.  This is a
      kernel-wide issue: kernel dev_t needs another name.

  2.  Don't export unnecessary kernel structures to userland.  This
      can be done within Vinum.  It is currently on the tuit queue.
