Core fixes:
- Defer GPIO device setup until after gpiolib is initialized.
It turns out that a few very tightly integrated GPIO platform
drivers initialize so early (befor core_initcall()) so that
the gpiolib isn't even initialized itself. That limits what
the library can do, and we cannot reference uninitialized
fields until later. Defer some of the initialization until
right after the gpiolib is initialized in these (rare) cases.
- As a consequence: do not use devm_* resources when allocating
the states in the initial set-up of the gpiochip.
Driver fixes:
- In ACPI retrieveal: ignore GpioInt when looking for output
GPIOs.
- Fix legacy builds on the PXA without a backing pin controller.
- Use correct datatype on pca953x register writes.

One staging driver patch reverts the deletion of a driver that happened
in 4.6-rc1. We thought that laptop.org was dead, but it's still alive

deleting a driver for their machines. So that driver is added back and

Signed-off-by: Helge Deller <deller@gmx.de>
Handling exceptions from modules never worked on parisc.
It was just masked by the fact that exceptions from modules
don't happen during normal use.
When a module triggers an exception in get_user() we need to load the
main kernel dp value before accessing the exception_data structure, and
afterwards restore the original dp value of the module on exit.

In legacy pxa builds, ie. non device-tree and platform-data only builds,
pinctrl is not yet available. As a consequence, the pinctrl gpio
direction change function is a stub, returning always success.
In the current state, the gpio driver direction function believes the
pinctrl direction change was successful, and exits without actually
changing the gpio direction.
This patch changes the logic :
- if the pinctrl direction function fails, gpio direction will report
that failure
- if the pinctrl direction function succeeds, gpio direction is changed
by the gpio driver anyway.
This is sub optimal in the pinctrl aware case, as the gpio direction
will be changed twice: once by pinctrl function and another time by
the gpio direction function.
Yet it should be acceptable in this form, as this is functional for all
pxa platforms (device-tree and platform-data), and moreover changing a
gpio direction is very very seldom, usually in machine initialization,
seldom in drivers probe, and an exception for ac97 reset bug.

When firmware does not use _DSD properties that allow properly name GPIO
resources, the kernel falls back on parsing _CRS resources, and will
return entries described as GpioInt() as general purpose GPIOs even
though they are meant to be used simply as interrupt sources for the
device:
Device (ETSA)
{
Name (_HID, "ELAN0001")
...
Method(_CRS, 0x0, NotSerialized)
{
Name(BUF0,ResourceTemplate ()
{
I2CSerialBus(
0x10, /* SlaveAddress */
ControllerInitiated, /* SlaveMode */
400000, /* ConnectionSpeed */
AddressingMode7Bit, /* AddressingMode */
"\\_SB.I2C1", /* ResourceSource */
)
GpioInt (Edge, ActiveLow, ExclusiveAndWake, PullNone,,
"\\_SB.GPSW") { BOARD_TOUCH_GPIO_INDEX }
} )
Return (BUF0)
}
...
}
This gives troubles with drivers such as Elan Touchscreen driver
(elants_i2c) that uses devm_gpiod_get to look up "reset" GPIO line and
decide whether the driver is responsible for powering up and resetting
the device, or firmware is. In the above case the lookup succeeds, we
map GPIO as output and later fail to request client->irq interrupt that
is mapped to the same GPIO.
Let's ignore resources described as GpioInt() while parsing _CRS when
requesting output GPIOs (but allow them when requesting GPIOD_ASIS or
GPIOD_IN as some drivers, such as i2c-hid, do request GPIO as input and
then map it to interrupt with gpiod_to_irq).

When section alignment padding is in effect we need to shift / truncate
the range that is queried for poison by the 'start_pad' or 'end_trunc'
reservations.
It's easiest if we just pass in an adjusted resource range rather than
deriving it from the passed in namespace. With the resource range
resolution pushed out to the caller we can also push the
namespace-to-region lookup to the caller and drop the implicit pmem-type
assumption about the passed in namespace object.

contexts properly. All the initializations performed by
srpt_alloc_ioctx() are skipped.
- It swaps the order of the send ioctx allocation and the transition to
RTR mode which is wrong.
- The amount of memory that is needed for I/O contexts is doubled.
- srpt_rdma_ch.free_list is no longer used but is not removed.

The IMX ones are for more stricter plane checks and some cleanups.
I'm off until Monday, so therre might be some fixes early next week if
anyone missed me"

When PAGE_SIZE > 4k single page can contain 2 RDS fragments. If
'rds_ib_cong_recv' ignore the RDS fragment offset in to the page it
then read the data fragment as far congestion map update and lead to
corruption of the RDS connection far congestion map.
