  Log:
  - Change the vm_mmap() function to accept an objtype_t parameter specifying
    the type of object represented by the handle argument.
  - Allow vm_mmap() to map device memory via cdev objects in addition to
    vnodes and anonymous memory.  Note that mmaping a cdev directly does not
    currently perform any MAC checks like mapping a vnode does.
  - Unbreak the DRM getbufs ioctl by having it call vm_mmap() directly on the
    cdev the ioctl is acting on rather than trying to find a suitable vnode
    to map from.
