Pull tty/serial driver updates from Greg KH:
 "Here's the big tty/serial driver update for 3.19-rc1.

  There are a number of TTY core changes/fixes in here from Peter Hurley
  that have all been teted in linux-next for a long time now.  There are
  also the normal serial driver updates as well, full details in the
  changelog below"

+Note: Aliases may be defined to ensure the correct ordering of the UARTs.
+The alias serialN will result in the UART being assigned port N.  If any
