bbbce516bb TTY/Serial fixes for 4.0-rc3
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.

dfd37668ea serial: 8250_dw: Fix get_mctrl behaviour
Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver

Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.

It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.

39ed853a24 Power management and ACPI fixes for v4.0-rc3
- Fix ACPI resources management problems introduced by the recent
    rework of the code in question (Jiang Liu) and a build issue
    introduced by those changes (Joachim Nilsson).
 
  - Fix a recent suspend-to-idle regression on systems where entering
    idle states causes local timers to stop, prevent suspend-to-idle
    from crashing in restricted configurations (no cpuidle driver,
    cpuidle disabled etc.) and clean up the idle loop somewhat while
    at it (Rafael J Wysocki).
 
  - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
 
  - Allow the ACPI backlight driver module to be loaded if ACPI is
    disabled which helps the i915 driver in those configurations
    (stable-candidate) and change the code to help debug unusual use
    cases (Chris Wilson).
 
  - Wakeup IRQ management changes in v3.18 caused some drivers on the
    at91 platform to trigger a warning from the IRQ core related to
    an unexpected combination of interrupt action handler flags.
    However, on at91 a timer IRQ is shared with some other devices
    (including system wakeup ones) and that leads to the unusual
    combination of flags in question.  To make it possible to avoid
    the warning introduce a new interrupt action handler flag (which
    can be used by drivers to indicate the special case to the core)
    and rework the problematic at91 drivers to use it and work as
    expected during system suspend/resume.  From Boris Brezillon,
    Rafael J Wysocki and Mark Rutland.
 
  - Clean up the generic power domains subsystem's debugfs interface
    (Kevin Hilman).

7438b633a6 genirq / PM: describe IRQF_COND_SUSPEND
With certain restrictions it is possible for a wakeup device to share
an IRQ with an IRQF_NO_SUSPEND user, and the warnings introduced by
commit cab303be91 are spurious. The new
IRQF_COND_SUSPEND flag allows drivers to tell the core when these
restrictions are met, allowing spurious warnings to be silenced.

This patch documents how IRQF_COND_SUSPEND is expected to be used,
updating some of the text now made invalid by its addition.

d2973697b3 mm: memcontrol: use "max" instead of "infinity" in control knobs
The memcg control knobs indicate the highest possible value using the
symbolic name "infinity", which is long and awkward to type.

Switch to the string "max", which is just as descriptive but shorter and
sweeter.

This changes a user interface, so do it before the release and before
the development flag is dropped from the default hierarchy.

737eb0301f genirq / PM: better describe IRQF_NO_SUSPEND semantics
The IRQF_NO_SUSPEND flag is intended to be used for interrupts required
to be enabled during the suspend-resume cycle. This mostly consists of
IPIs and timer interrupts, potentially including chained irqchip
interrupts if these are necessary to handle timers or IPIs. If an
interrupt does not fall into one of the aforementioned categories,
requesting it with IRQF_NO_SUSPEND is likely incorrect.

Using IRQF_NO_SUSPEND does not guarantee that the interrupt can wake the
system from a suspended state. For an interrupt to be able to trigger a
wakeup, it may be necessary to program various components of the system.
In these cases it is necessary to use {enable,disabled}_irq_wake.

Unfortunately, several drivers assume that IRQF_NO_SUSPEND ensures that
an IRQ can wake up the system, and the documentation can be read
ambiguously w.r.t. this property.

This patch updates the documentation regarding IRQF_NO_SUSPEND to make
this caveat explicit, hopefully making future misuse rarer. Cleanup of
existing misuse will occur as part of later patch series.

74ad752442 amd-xgbe-phy: PHY KX/KR mode differences
The PHY requires different settings for the Decision Feedback Analyzer
(DFE) when running in KX mode vs. KR mode. Update the code to change
these settings when changing modes in order to provide a more stable
link.

Additionally, adjust the 10GbE PQ skew default setting to a more sane
value.

 "This is the main pull request for MIPS:

   - a number of fixes that didn't make the 3.19 release.

   - a number of cleanups.

   - preliminary support for Cavium's Octeon 3 SOCs which feature up to
     48 MIPS64 R3 cores with FPU and hardware virtualization.

   - support for MIPS R6 processors.

     Revision 6 of the MIPS architecture is a major revision of the MIPS
     architecture which does away with many of original sins of the
     architecture such as branch delay slots.  This and other changes in
     R6 require major changes throughout the entire MIPS core
     architecture code and make up for the lion share of this pull
     request.

   - finally some preparatory work for eXtendend Physical Address
     support, which allows support of up to 40 bit of physical address
     space on 32 bit processors"

18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

53861af9a1 OK, this has the big virtio 1.0 implementation, as specified by OASIS.
On top of tht is the major rework of lguest, to use PCI and virtio 1.0, to
 double-check the implementation.
 
 Then comes the inevitable fixes and cleanups from that work.
 
 Thanks,

ba804a9510 watchdog: gpio_wdt: Add "always_running" feature to GPIO watchdog
On some chips, like the TPS386000, the trigger cannot be disabled
and the CPU must keep toggling the line at all times. Add a switch
"always_running" to keep toggling the GPIO line regardless of the
state of the soft part of the watchdog. The "armed" member keeps
track of whether a timeout must also cause a reset.

 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down

878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

ea7531ac4a ARM: SoC cleanups
This is a good healthy set of various code removals. Total net delta is 8100
 lines removed.
 
 Among the larger cleanups are:
 
 - Removal of old Samsung S3C DMA infrastructure by Arnd
 - Removal of the non-DT version of the 'lager' board by Magnus Damm
 - General stale code removal on OMAP and Davinci by Rickard Strandqvist
 - Removal of non-DT support on am3517 platforms by Tony Lindgren
 
 ... plus several other cleanups of various platforms across the board.
