gpio: max732x: Fix possible NULL pointer dereference on i2c_new_dummy error
In max732x_probe() driver allocates dummy I2C device (if number of ports
is greater than 8) with i2c_new_dummy() but it does not check the return
value of this call.
In case of error (i2c_new_device(): memory allocation failure or I2C
address cannot be used) this function returns NULL which is later
dereferenced by i2c_smbus_read_byte() (called from max732x_readb()).

The driver missed an of_xlate function to translate gpio numbers
as found in the DT to the correct chip and number.
While there I've set #gpio_cells to a fixed value of 2.
I've used gpio-pxa.c as template for those changes and tested my changes
successfully on a da850 board using entries for gpio-leds in a DT. So I didn't
reinvent the wheel but just copied and tested stuff.
Thanks to Grygorii Strashko for the hint to the existing code in gpio-pxa.

gpio: adp5588: get value from data out when dir is out
As discussed here: http://ez.analog.com/message/35852,
the 5587 revC and 5588 revB spec sheets contain a mistake
in the GPIO_DAT_STATx register description.
According to R.Shnell at ADI, as well as my own
observations, it should read:
"GPIO data status (shows GPIO state when read for inputs)".
This commit changes the get value function accordingly.
Some drivers dealing with a gpio_chip might need to act on its
descriptors directly; one example is pinctrl drivers that need to lock a
GPIO for being used as IRQ using gpiod_lock_as_irq().
This patch exports a gpiochip_get_desc() function that returns the
GPIO descriptor at the requested index. It also sweeps the
gpio_to_chip() function out of the consumer interface since any holder
of a gpio_chip reference can manipulate its GPIOs way beyond what a
consumer should be allowed to do.
As a result, gpio_chip is not visible anymore to simple GPIO consumers.
gpio: mvebu: use chained_irq_{enter,exit} for GIC compatibility
On currently supported SoCs, the GPIO block used on Marvell EBU SoCs
is always connected to the Marvell MPIC. However, we are going to
introduce the support for newer Marvell EBU SoCs that use the
Cortex-A9 core, and therefore use the GIC as their main interrupt
controller, to which the GPIO block controlled by the gpio-mvebu
driver is connected.
The GIC interrupt controller driver uses the fasteoi flow handler. In
order to ensure that the eoi hook of the GIC driver gets called, the
GPIO driver should call chained_irq_enter() and chained_irq_exit() in
its handler. Without this, the first GPIO interrupt locks up the
system because it doesn't get acked at the GIC level.

hpfs: optimize quad buffer loading
HPFS needs to load 4 consecutive 512-byte sectors when accessing the
directory nodes or bitmaps. We can't switch to 2048-byte block size
because files are allocated in the units of 512-byte sectors.
Previously, the driver would allocate a 2048-byte area using kmalloc,
copy the data from four buffers to this area and eventually copy them
back if they were modified.
In the current implementation of the buffer cache, buffers are allocated
in the pagecache. That means that 4 consecutive 512-byte buffers are
stored in consecutive areas in the kernel address space. So, we don't
need to allocate extra memory and copy the content of the buffers there.
This patch optimizes the code to avoid copying the buffers. It checks
if the four buffers are stored in contiguous memory - if they are not,
it falls back to allocating a 2048-byte area and copying data there.

New versions of wine are hammering on the statfs syscall very heavily,

times in minutes.
This should be backported to the stable kernels because it fixes

Revert "PCI: Remove from bus_list and release resources in pci_release_dev()"
Revert commit ef83b0781a73 "PCI: Remove from bus_list and release
resources in pci_release_dev()" that made some nasty race conditions
become possible. For example, if a Thunderbolt link is unplugged
and then replugged immediately, the pci_release_dev() resulting from
the hot-remove code path may be racing with the hot-add code path
which after that commit causes various kinds of breakage to happen
(up to and including a hard crash of the whole system).
Moreover, the problem that commit ef83b0781a73 attempted to address
cannot happen any more after commit 8a4c5c329de7 "PCI: Check parent
kobject in pci_destroy_dev()", because pci_destroy_dev() will now
return immediately if it has already been executed for the given
device.
Note, however, that the invocation of msi_remove_pci_irq_vectors()
removed by commit ef83b0781a73 from pci_free_resources() along with
the other changes made by it is not added back because of subsequent
code changes depending on that modification.

ARM: multi_v7_defconfig: remove redundant entries and re-enable TI_EDMA
TI_EDMA fell out of automatically selected options in the multi_v7
defconfig due to a select being removed from the davinci Kconfig entry. So
we need to re-enable explicitly to not regress some platforms.
The rest is just the result of running 'make multi_v7_defconfig + make
savedefconfig' to remove entries that are no longer needed due to changed
dependencies/selects or defaults.
