Pull swiotlb fixes from Konrad Rzeszutek Wilk:
"This has one fix to make i915 work when using Xen SWIOTLB, and a
feature from Geert to aid in debugging of devices that can't do DMA
outside the 32-bit address space.
The feature from Geert is on top of v4.10 merge window commit
(specifically you pulling my previous branch), as his changes were
dependent on the Documentation/ movement patches.
I figured it would just easier than me trying than to cherry-pick the
Documentation patches to satisfy git.
The patches have been soaking since 12/20, albeit I updated the last
patch due to linux-next catching an compiler error and adding an
Tested-and-Reported-by tag"

"These fix a device enumeration problem related to _ADR matching and an
IOMMU initialization issue related to the DMAR table missing, remove
an excessive function call from the core ACPI code, update an error
message in the ACPI WDAT watchdog driver and add a way to work around
problems with unhandled GPE notifications.
Specifics:
- Fix a device enumeration issue leading to incorrect associations
between ACPI device objects and platform device objects
representing physical devices if the given device object has both
_ADR and _HID (Rafael Wysocki).
- Avoid passing NULL to acpi_put_table() during IOMMU initialization
which triggers a (rightful) warning from ACPICA (Rafael Wysocki).
- Drop an excessive call to acpi_dma_deconfigure() from the core code
that binds ACPI device objects to device objects representing
physical devices (Lorenzo Pieralisi).
- Update an error message in the ACPI WDAT watchdog driver to make it
provide more useful information (Mika Westerberg).
- Add a mechanism to work around issues with unhandled GPE
notifications that occur during system initialization and cannot be
prevented by means of sysfs (Lv Zheng)"

Pull ARM SoC fixes from Arnd Bergmann:
"This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
regressions introduced during the merge window, and about half of the
changes are for mach-omap2.
A couple of patches are just cleanups and dead code removal that I
would not normally have considered for merging after -rc2, but I
decided to take them along with the fixes this time.
Notable fixes include:
- removing the skeleton.dtsi include broke a number of machines, and
we have to put empty /chosen nodes back to be able to pass kernel
command lines as before
- enabling Samsung platforms no longer hardwires CONFIG_HZ to 200, as
it had been for no good reason for a long time"

The references to drivers/base/power/main.c and
drivers/acpi/scan.c from Documentation/driver-api/infrastructure.rst
are confusing. They both cause descriptions of functions that are
not relevant to device drivers at all to be generated and none of
them is sufficient to cover the API in a meaningful way.
Drop them for now.

Sometimes, the users may require a quirk to be provided from ACPI subsystem
core to prevent a GPE from flooding.
Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents
the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx
provided via AML table, and OSPM is lacking of the knowledge to get
_Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may
still occur.
The existing quirk mechanism can be enabled/disabled using the following
commands to prevent such kind of GPE flooding during runtime:
# echo mask > /sys/firmware/acpi/interrupts/gpe00
# echo unmask > /sys/firmware/acpi/interrupts/gpe00
To avoid GPE flooding during boot, we need a boot stage mechanism.
This patch provides such a boot stage quirk mechanism to stop this kind of
GPE flooding. This patch doesn't fix any feature gap but since the new
feature gaps could be found in the future endlessly, and can disappear if
the feature gaps are filled, providing a boot parameter rather than a DMI
table should suffice.
