The DesignWare GPIO IP can be configured for either 1 interrupt or 1
per GPIO in port A, but the driver currently only supports 1 interrupt.
See the DesignWare DW_apb_gpio Databook description of the
'GPIO_INTR_IO' parameter.
This change allows the driver to work with up to 32 interrupts, it will
get as many interrupts as specified in the DT 'interrupts' property.
It doesn't do anything clever with the different interrupts, it just calls
the same handler used for single interrupt hardware.
ACPI companion code provided by Hoan Tran <hotran@apm.com>. This was tested
on X-Gene by Hoan.

This is a driver so we should only include <linux/gpio/driver.h>.
However this driver was using gpio_get_value() to fetch the
current value of a GPIO used as IRQ line to determine trigger
direction, so we need a better way than looping over the
global GPIO numberspace.
Fix this by just calling the .get() function in the GPIO chip,
as we don't want to end up creating a consumer dependency
on ourselves.

The MVEBU driver is requesting GPIO descriptors from itself, which
is fine, but we have proper APIs to do this in a controlled way, so
stop calling into the private functions of the GPIO library and use
the gpiochip_* functions instead. Only include <linux/gpio/driver.h>
and <linux/gpio/consumer.h> since we are both producers and consumers
in this case.

It is pretty helpful to create some kind of device for backing the
GPIO chips, especially when preparing the driver for using
GENERIC_GPIO, so let's create a simple platform device and a simple
platform device driver and create the gpiochip in the .probe() routine
for the device driver. Keep all at the core initcall so the behaviour
is the same as before.

Board files constitute a significant part of the users of the legacy
GPIO framework. In many cases they only export a line and set its
desired value. We could use GPIO hogs for that like we do for DT and
ACPI but there's no support for that in machine code.
This patch proposes to extend the machine.h API with support for
registering hog tables in board files.

Pull SCSI fixes from James Bottomley:
"This is a set of minor (and safe changes) that didn't make the initial
pull request plus some bug fixes.
The status handling code is actually a running regression from the
previous merge window which had an incomplete fix (now reverted) and
most of the remaining bug fixes are for problems older than the
current merge window"
[ Side note: this merge also takes the base kernel git repository to 6+
million objects for the first time. Technically we hit it a couple of
merges ago already if you count all the tag objects, but now it
reaches 6M+ objects reachable from HEAD.
I was joking around that that's when I should switch to 5.0, because
3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
probably not, even if numerology is about as good a reason as any.

Pull irq affinity fixes from Thomas Gleixner:
- Fix error path handling in the affinity spreading code
- Make affinity spreading smarter to avoid issues on systems which
claim to have hotpluggable CPUs while in fact they can't hotplug
anything.
So instead of trying to spread the vectors (and thereby the
associated device queues) to all possibe CPUs, spread them on all
present CPUs first. If there are left over vectors after that first
step they are spread among the possible, but not present CPUs which
keeps the code backwards compatible for virtual decives and NVME
which allocate a queue per possible CPU, but makes the spreading
smarter for devices which have less queues than possible or present
CPUs.
* 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
genirq/affinity: Spread irq vectors among present CPUs as far as possible
genirq/affinity: Allow irq spreading from a given starting point
genirq/affinity: Move actual irq vector spreading into a helper function
genirq/affinity: Rename *node_to_possible_cpumask as *node_to_cpumask
genirq/affinity: Don't return with empty affinity masks on error

Pull OpenRISC fixlet from Stafford Horne:
"Just one small thing here, it came in a while back but I didnt have
anything in my 4.16 queue, still its the only thing for 4.17 so
sending it alone.
Small cleanup: remove unused __ARCH_HAVE_MMU define"

Pull powerpc fixes from Michael Ellerman:
- Fix crashes when loading modules built with a different
CONFIG_RELOCATABLE value by adding CONFIG_RELOCATABLE to vermagic.
- Fix busy loops in the OPAL NVRAM driver if we get certain error
conditions from firmware.
- Remove tlbie trace points from KVM code that's called in real mode,
because it causes crashes.
- Fix checkstops caused by invalid tlbiel on Power9 Radix.
- Ensure the set of CPU features we "know" are always enabled is
actually the minimal set when we build with support for firmware
supplied CPU features.
Thanks to: Aneesh Kumar K.V, Anshuman Khandual, Nicholas Piggin.

The code to verify the new kernels sha digest is applicable for all
architectures. Move it to common code.
One problem is the string.c implementation on x86. Currently sha256
includes x86/boot/string.h which defines memcpy and memset to be gcc
builtins. By moving the sha256 implementation to common code and
changing the include to linux/string.h both functions are no longer
defined. Thus definitions have to be provided in x86/purgatory/string.c
