Apart from some code inside ttm itself and nouveau_bo_vma_del,
this is the only place where ttm_bo_wait is used without a reservation.
Fix this so we can remove the fence_lock later on.

removed again.

Currently the loadparm is only supported for CCW IPL. But also for SCSI
IPL it can be specified either on the HMC load panel respectively
z/VM console or via diagnose 308.
So fix this for SCSI and add the required sysfs attributes for reading the
IPL loadparm and for setting the loadparm for re-IPL.
With this patch the following two sysfs attributes are introduced:
- /sys/firmware/ipl/loadparm (for system that have been IPLed from SCSI)
- /sys/firmware/reipl/fcp/loadparm
Because the loadparm is now available for SCSI and CCW it is moved
now from "struct ipl_block_ccw" to the generic "struct ipl_list_hdr".

will make a new attempt for 3.18. I didn't see a need for a full revert of the whole

The rest is mostly:

* Some MTD/NAND fixes for OMAP
* Minor DT fixes for shmobile
* Warning fix for UP builds on vexpress/spc
There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
so it can boot. Drivers and the rest had landed for 3.17, and it's small

The quirk indicating whether the trf7970a has
the "IRQ Status Read" erratum or not is currently
implemented using the 'driver_data' member of the
'spi_device_id' structure. That requires the
driver to be modified to turn the quirk off when
a version of the trf7970a that doesn't have the
erratum is being used. To fix that, create a
new device tree property called
'irq-status-read-quirk' that indicates that the
trf7970a being used has the erratum.
While at it, rename 'TRF7970A_QUIRK_IRQ_STATUS_READ_ERRATA'

The trf7970a driver recently had support for the
'vin-voltage-override' property added to it. This
property is used to override the value given by
the regulator subsystem for the VIN pin's voltage.
Signed-off-by: Mark A. Greer <mgreer@animalcreek.com>
Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
The trf7970a driver uses the voltage from the
power/regulator subsystem to determine what the
voltage on the VIN pin is. Normally, this is
the right thing to do but sometimes the board
that the trf7970a is on may change the voltage.
This is the case for the trf7970atb board from
Texas Instruments where it boosts the VIN voltage
from 3.3V to 5V (see http://www.ti.com/tool/trf7970atb).
To handle this, add support for the 'vin-voltage-override'
device tree property which overrides the voltage value
given by the regulator subsystem. When the DT property
is not present, the value from the regulator subsystem
is used.
The value of 'vin-voltage-override' is in uVolts.
