* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6: (49 commits)
  serial8250: ratelimit "too much work" error
  serial: bfin_sport_uart: speed up sport RX sample rate to be 3% faster
  serial: abstraction for 8250 legacy ports
  serial/imx: check that the buffer is non-empty before sending it out
  serial: mfd: add more baud rates support
  jsm: Remove the uart port on errors
  Alchemy: Add UART PM methods.
  8250: allow platforms to override PM hook.
  altera_uart: Don't use plain integer as NULL pointer
  altera_uart: Fix missing prototype for registering an early console
  altera_uart: Fixup type usage of port flags
  altera_uart: Make it possible to use Altera UART and 8250 ports together
  altera_uart: Add support for different address strides
  altera_uart: Add support for getting mapbase and IRQ from resources
  altera_uart: Add support for polling mode (IRQ-less)
  serial: Factor out uart_poll_timeout() from 8250 driver
  serial: mark the 8250 driver as maintained
  serial: 8250: Don't delay after transmitter is ready.
  tty: MAINTAINERS: add drivers/serial/jsm/ as maintained driver
  vcs: invoke the vt update callback when /dev/vcs* is written to
