Pull tty/serial fixes from Greg KH:
 "Here are some tty and serial driver fixes for 4.0-rc3.

  Along with the atime fix that you know about, here are some other
  serial driver bugfixes as well.  Most notable is a wait_until_sent
  bugfix that was traced back to being around since before 2.6.12 that
  Johan has fixed up.

  All have been in linux-next successfully"

  serial: 8250: Revert "tty: serial: 8250_core: read only RX if there is something in the FIFO"
  Revert "tty/serial: of_serial: add DT alias ID handling"

In case an infinite timeout (0) is requested, the irda wait_until_sent
implementation would use a zero poll timeout rather than the default
200ms.

Note that wait_until_sent is currently never called with a 0-timeout
argument due to a bug in tty_wait_until_sent.

Use helper functions to access current->state.
Direct assignments are prone to races and therefore buggy.

current->state = TASK_RUNNING can be replaced by __set_current_state()

Thanks to Peter Zijlstra for the exact definition of the problem.

This is only an API consolidation and should make things more readable
it replaces  var * HZ / 1000  constructs by  msecs_to_jiffies(var).

Making things const is a good thing.

sge.c was overlapping two changes, one to use the new
__dev_alloc_page() in net-next, and one to use s->fl_pg_order in net.

ixgbe_phy.c was a set of overlapping whitespace changes.

Fix the build failures that result from the use of pr_debug

Use the normal kernel debugging mechanism which also
enables dynamic_debug at the same time.

Other miscellanea:

o Remove sysctl for irda_debug
o Remove function tracing like uses (use ftrace instead)
o Coalesce formats
o Realign arguments
o Remove unnecessary OOM messages
