f96884574d ARM: dts: TWL4030: fix mux and wakeup for SYS_NIRQ line
On most OMAP3 platforms, the twl4030 IRQ line is connected to the
SYS_NIRQ line on OMAP.  Add another DTS include file
(twl4030_omap3.dtsi) for boards that hook up the twl4030 this way
to include.

This allows RTC wake from off-mode to work again on OMAP3-based
platforms with twl4030.  Tested on 3530/Beagle, 3730/Beagle-xM,
3530/Overo, 3730/Overo-STORM.

Special thanks to Florian Vaussard for suggesting use of preprocessor
feature.

Using the gpio-keys bindings, configure the user button on Beagle

ensure the GPIO pin is mux'd correctly and has IO ring wakeups enabled,
so it can also wakeup from off mode.

fa63d03728 ARM: dts: omap5: Make uevm as the official board and deprecate sevm support
The uevm is the only official board supported for the OMAP5 soc
in mainline. The existent sevm platform will no more be supported.
Hence cleaning up the board dts file to have only the data
required for uevm.

Renaming the board dts file and adding the following cleanups.

 * There are no devices connected on I2C 2,3,4 buses. So remove
   the pinmux data for the same.

 * OMAP5432 and DDR3 memory is used in the uevm. Temperature polling
   is not supported with DDR3 memories. Because of DDR3 phy limitation
   the voltage change across DVFS and all shadow registers for DVFS on
   DDR3 is not supported. Hence the emif kernel driver is not required,
   so removing the DDR3 device file and emif nodes for uevm.

 * Keypad is not supported on uevm. So remove the device node.

958c4eb2aa ACPI / LPSS: override SDIO private register space size from ACPI tables
The SDIO device in Lynxpoint has its LTR registers reserved for a
WiFi device (a child of the SDIO device) in the ACPI namespace even
though those registers physically belong to the SDIO device itself.
In order to be able to access the SDIO LTR registers from the ACPI
LPSS driver for diagnostic purposes we need to use a size override
for the SDIO private register space.

Add a possibility to override the size of the private register space
of an LPSS device provided by the ACPI tables in the ACPI LPSS driver
and set the correct size for the SDIO device in there.

06d8641504 ACPI / LPSS: mask the UART TX completion interrupt
Intel LPSS provides an extra TX byte counter and an extra TX
completion interrupt for some of its bus controllers.  However,
there is no use for the extra UART interrupt and it has to be
masked out during initialization.

Otherwise, if the firmware does not mask the interrupt and
the driver does not clear it, it may cause an interrupt flood
freezing the board to happen.

Add code masking that problematic interrupt to the ACPI LPSS driver.

6c62a895e5 FMC: add a software carrier driver
This fake carrier is designed to help FMC users understand how a
carrier driver works, and to experiment the behaviour with EEPROM
reprogramming (with a mezzanine driver commited later). This carrier
can register up to 4 (fake) mezzanines.

We have real carriers (both on PCI-E and VME), but they are bigger
things and are not part of this submission.

This is selected sections of the current manual for fmc-bus, as
developed outside of the kernel before submission.

Like the other patches in this set, it corresponds to commit ab23167f of

77864f2e0a FMC: add core bus driver
This module offers registration services for both carriers
(i.e. devices) and mezzanines (i.e. drivers). The matching for devices
and drivers is performed according to the IPMI standard for FRU
devices (Field Replaceable Units).

The code includes support for parsing an SDB tree if present in the FPGA,
and dumping it for diagnostics. SDB is not mandatory.

Files in this commit correspond to commit ab23167f in the master branch
of the project hosted on ohwr.org.

7b175c4672 MAINTAINERS: add stable_kernel_rules.txt to stable maintainer information
This hopefully will help point developers to the proper way that patches
should be submitted for inclusion in the stable kernel releases.

e6abf12a77 kconfig/conf: fix randconfig setting multiple symbols in a choice
Currently, randconfig may set more than one symbol in a given choice.
Given this config file:
    config A
        bool "A"
    if A
    choice
        bool "B/C/D"
    config B
        bool "B"
    config C
        bool "C"
    config D
        bool "D"
    endchoice
    endif # A

Then randconfig generates such .config files (case where A is not set is not
shown below for brevity), and where only the right-most .config is valid:
  CONFIG_A=y                  CONFIG_A=y                  CONFIG_A=y
  CONFIG_B=y                  CONFIG_B=y                  CONFIG_B=y
  CONFIG_C=y                  # CONFIG_C is not set       # CONFIG_C is not set
  # CONFIG_D is not set       CONFIG_D=y                  # CONFIG_D is not set

That is, in a randomised choice, the first symbol is always selected,
and at most one other symbol may be selected.

This is due to symbol randomised in a choice not being properly flagged
as having a value.

Fix that by flagging those symbols adequately: have a user-defined value,
and be not valid (to force recalculation of the symbol).

Note: if the choice is not conditional, then the randomisation is properly
done.
