  Log:
  Almost nine years ago, when support for 1TB files was introduced in
  revision 1.55, the address parameter to vnode_pager_addr() was changed
  from an unsigned 32-bit quantity to a signed 64-bit quantity.  However,
  an out-of-range check on the address was not updated.  Consequently,
  memory-mapped I/O on files greater than 2GB could cause a kernel panic.
  Since the address is now a signed 64-bit quantity, the problem resolution
  is simply to remove a cast.
