  Log:
  MFC revision 1.206
   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.
