Pull driver core updates from Greg Kroah-Hartman:
"Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This
is going to be a pain for the merge with different subsystem trees, I
know, but all of the patches included here have been ACKed by their
various subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them
all, it's up to you. The merges should all be trivial, and Stephen
has been doing them all in linux-next for a few weeks now quite
easily.
Other than the __dev* marking removals, there's nothing major here,
some firmware loading updates and other minor things in the driver
core.
All of these have (much to Stephen's annoyance), been in linux-next
for a while.

gpio_chip.can_sleep is 0, but current code uses mutex in pch_gpio_set
pch_gpio_get and pch_gpio_direction_input functions.
Thus those functions are not callable from interrupt context.
This patch converts mutex into spinlock.

Pull GPIO driver changes from Grant Likely:
"Lots of gpio changes, both to core code and drivers.
Changes do touch architecture code to remove the need for separate
arm/gpio.h includes in most architectures.
Some new drivers are added, and a number of gpio drivers are converted
to use irq_domains for gpio inputs used as interrupts. Device tree
support has been amended to allow multiple gpio_chips to use the same
device tree node.
Remaining changes are primarily bug fixes."

This patch converts the drivers in drivers/gpio/* to use
module_pci_driver() macro which makes the code smaller and a bit
simpler by having less boilerplate.

Jean-Francois Dagenais reported:
Configuring a gpio pin with the gpio-pch driver with
"IRQF_TRIGGER_LOW | IRQF_ONESHOT" generates an interrupt storm for
threaded ISR until the ISR thread actually gets to physically clear
the interrupt on the triggering chip!! The immediate observable
symptom is the high CPU usage for my ISR thread task and the
interrupt count in /proc/interrupts incrementing radically.
The driver is wrong in several ways:
1) Using handle_simple_irq() does not provide proper flow control
handling. In the case of oneshot threaded handlers for the
demultiplexed interrupts this results in an interrupt storm because
the simple handler does not deal with masking/unmasking. Even
without threaded oneshot handlers an interrupt storm for level type
interrupts can easily be triggered when the interrupt is disabled
and the interrupt line is activated from the device.
2) Acknowlegding the demultiplexed interrupt before calling the
handler is wrong for level type interrupts.
3) The set_type function unconditionally enables the interrupt. It's
supposed to set the type and nothing else. The unmasking is done by
the core code.
Move the acknowledge code into a separate function and add it to the
demux irqchip callbacks.
Remove the unconditional enabling from the set_type() callback and set
the proper flow handlers depending on the selected type (level/edge).

The __iomem annotation is to be used together with pointers used
as iowrite32() parameter. For more details see [1] and [2].
This patch will remove the following sparse warnings ("make C=1"):
* warning: incorrect type in assignment (different address spaces)
* warning: incorrect type in argument 1 (different address spaces)
* warning: incorrect type in argument 2 (different address spaces)

Currently, GFP_KERNEL is used as parameter of irq_alloc_descs like below.
irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j],
GFP_KERNEL);
This is not true.
So, this patch uses NUMA_NO_NODE not GFP_KERNEL.
