6454588092 vt: break a couple of obsolete SCOish codes.
No modern terminal supports them, and SGR 38 conflicts with detecting
xterm-256 colours.  This also makes SGR 39 consistent with other popular
terminals.  Neither are used by ncurses' terminfo.

1926d0aeec hvc_vio: Do not override preferred console set by kernel parameter
The original version of this was done by Bastian Blank, who wrote:

> The problem is the following:
> - Architecture specific code sets preferred console to something bogus.
> - Command line handling tries to set preferred console but is overruled
>   by the old setting.
>
> The udbg0 console is a boot console and independant.

216fce2e78 serial: clps711x: drop needless devm_clk_put
The nice thing about devm_* is that the driver doesn't need to free the
resources but the driver core takes care about that.

These calls were introduced in commit c08f015 (serial: clps711x: Using
CPU clock subsystem for getting base UART speed).

f377775dc0 TTY: hvc_dcc: probe for a JTAG connection before registering
Enabling the ARM DCC console and using without a JTAG connection will
simply hang the system. Since distros like to turn on all options, this
is a reoccurring problem to debug. We can do better by checking if
anything is attached and handling characters. There is no way to probe
this, so send a newline and check that it is handled.

03e1261778 tty: disassociate_ctty() sends the extra SIGCONT
Starting from v3.10 (probably commit f91e259041: "tty: Signal
foreground group processes in hangup") disassociate_ctty() sends SIGCONT
if tty && on_exit.  This breaks LSB test-suite, in particular test8 in
_exit.c and test40 in sigcon5.c.

Put the "!on_exit" check back to restore the old behaviour.

Review by Peter Hurley:
 "Yes, this regression was introduced by me in that commit.  The effect
  of the regression is that ptys will receive a SIGCONT when, in similar
  circumstances, ttys would not.

  The fact that two test vectors accidentally tripped over this
  regression suggests that some other apps may as well.

  Thanks for catching this"

Pull powerpc updates from Ben Herrenschmidt:
 "Here's the powerpc batch for this merge window.  Some of the
  highlights are:

   - A bunch of endian fixes ! We don't have full LE support yet in that
     release but this contains a lot of fixes all over arch/powerpc to
     use the proper accessors, call the firmware with the right endian
     mode, etc...

   - A few updates to our "powernv" platform (non-virtualized, the one
     to run KVM on), among other, support for bridging the P8 LPC bus
     for UARTs, support and some EEH fixes.

   - Some mpc51xx clock API cleanups in preparation for a clock API
     overhaul

   - A pile of cleanups of our old math emulation code, including better
     support for using it to emulate optional FP instructions on
     embedded chips that otherwise have a HW FPU.

   - Some infrastructure in selftest, for powerpc now, but could be
     generalized, initially used by some tests for our perf instruction
     counting code.

   - A pile of fixes for hotplug on pseries (that was seriously
     bitrotting)

   - The usual slew of freescale embedded updates, new boards, 64-bit
     hiberation support, e6500 core PMU support, etc..."

There are cleanups for some mpc5121 specific drivers and DTS files
in preparation to switch mpc5121 clock support to a clock driver
based on common clock framework. Additionally Sebastian fixed the

Here's the big tty/serial driver pull request for 3.12-rc1.
 
 Lots of n_tty reworks to resolve some very long-standing issues, removing the
 3-4 different locks that were taken for every character.  This code has been
 beaten on for a long time in linux-next with no reported regressions.
 
 Other than that, a range of serial and tty driver updates and revisions.  Full

dd910d98a2 tty: ar933x_uart: add device tree support and binding documentation
Modify the probe routine to get the port line number
from device tree if the 'of_node' is populated in the
platform device. The driver can be built as module,
thus add an OF specific module device table as well
to support module auto loading.

This makes it possible to use the driver for AR9330
UART devices specified in device tree.

1241553513 tty: ar933x_uart: use config_enabled() macro to clean up ifdefs
Add a new ar933x_uart_console_enabled() helper function
which uses the config_enable(CONFIG_SERIAL_AR933X_CONSOLE)
macro to decide if the console support is enabled or not.

Remove the 'ifdef CONFIG_SERIAL_AR933X_CONSOLE' statements
and use the new helper function to conditionally enable
console support instead.

If CONFIG_SERIAL_AR933X_CONSOLE is not enabled, the new
helper function will become a null stub which allows the
compiler to optimize out the unused console specific
functions/variables.
