The acpi_table_parse() function has a callback that
passes a pointer to a table_header. Add a new function
which takes this pointer and parses its entries. This
eliminates the need to re-traverse all the tables for
each call. e.g. as in acpi_table_parse_madt() which is
normally called after acpi_table_parse().

Third set of IIO fixes for the 3.18 cycle.
Most of these are fairly standard little fixes, a bmc150 and bmg160 patch
is to make an ABI change to indicated a specific axis in an event rather
than the generic option in the original drivers. As both of these drivers
are new in this cycle it would be ideal to push this minor change through
even though it isn't strictly a fix. A couple of other 'fixes' change
defaults for some settings on these new drivers to more intuitive calues.
Looks like some useful feedback has been coming in for this driver
since it was applied.
* IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while
0xCF clearly doesn't give a contiguous bitmask.
* kxcjk-1013 range setting was failing to mask out the previous value
in the register and hence was 'enable only'.
* men_z188 device id table wasn't null terminated.
* bmg160 and bmc150 both failed to correctly handling an error in mode
setting.
* bmg160 and bmc150 both had a bug in setting the event direction in the
event spec (leads to an attribute name being incorrect)
* bmg160 defaulted to an open drain output for the interrupt - as a default
this obviously only works with some interrupt chips - hence change the
default to push-pull (note this is a new driver so we aren't going to
cause any regressions with this change).
* bmc150 had an unintuitive default for the rate of change (motion detector)
so change it to 0 (new driver so change of default won't cause any
regressions).

Drivers can use the of_regulator_match() function to parse the regulator
init_data from DT. A match table is used to specify the name of the node
containing the regulators, the device node and to return the init_data
to the caller.
But also the static regulator descriptor is needed to correctly extract
some DT properties like the regulator initial and suspend modes. Use the
match table to pass that information.

The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).
Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.
of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.

The "regulator-initial-mode" and "regulator-mode" DT properties allows
to configure the regulator operating modes at startup or when a system
enters into a susend state.
But these properties use as valid values the operating modes supported
by each device while the core deals with the standard operating modes.
So a mapping function is needed to translate from the hardware specific
modes to the standard ones.
This mapping is a non-varying configuration for each regulator, so add
a function pointer to struct regulator_desc that will allow drivers to
define their callback to do the modes translation.

There are two SPI controllers exported by PCI subsystem for Intel Quark X1000.
The SPI memory mapped I/O registers supported by Quark are different from
the current implementation, and Quark only supports the registers of 'SSCR0',
'SSCR1', 'SSSR', 'SSDR', and 'DDS_RATE'. This patch is to enable the SPI for
Intel Quark X1000.
This piece of work is derived from Dan O'Donovan's initial work for Intel Quark
X1000 SPI enabling.

The basic GICv3 driver has almost no use for the redistributor

a lot more from them.
As such, rework the set of data structures. The behaviour of the

This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in
kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn.
The problem being addressed by the patch above was that some ARM code
based the memory mapping attributes of a pfn on the return value of
kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should
be mapped as device memory.
However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,
and the existing non-ARM users were already using it in a way which
suggests that its name should probably have been 'kvm_is_reserved_pfn'
from the beginning, e.g., whether or not to call get_page/put_page on
it etc. This means that returning false for the zero page is a mistake
and the patch above should be reverted.

omap_hsmmc supports only one slot per controller, see OMAP_MMC_MAX_SLOTS.
This unnecessary indirection leads to confusion in the omap_hsmmc driver.
For example the card_detect callback is not installed by platform code
but from the driver probe function. So it should be a field of
omap_hsmmc_host. But since it is declared under the platform slot while
the drivers struct omap_hsmmc_host has no slot abstraction, this looks
like a bug, especially when not familiar that this driver only supports
1 slot anyway.
Either we should add a slot abstraction to omap_hsmmc_host or remove
it from the platform data struct. Removed since slot multiplexing is
an un-implemented feature

- omap mmc driver supports multiplexing, omap_mmc_hs doesn't
this leads to one of the major confusions in the omap_hsmmc driver
- platform data should be read-only for the driver
most callbacks are not set by the omap3 platform init code while still
required. So they are set from the driver probe function, which is against
the paradigm that platform-data should not be modified by the driver
typical examples are card_detect, read_only callbacks
un-bundling by searching for driver name \"omap_hsmmc in the
arch/arm folder. omap_hsmmc_platform_data is not initialized directly,
but from omap2_hsmmc_info, which is defined in a separate header file
not touched by this patch
hwmod includes platform headers to declare features of the platform. All
the declared features are prefixed OMAP_HSMMC. There is no need to
include platform header from hwmod other except for feature defines

MMC core already has support for HS400. Add HS400
support to SDHCI driver. The SDHC Standard specification
does not define HS400 so consequently HS400 support is
non-standard. However HS400 is not selected without
the host controller setting the corresponding capability
flags so host controllers not yet supporting HS400
will not be affected. To support that, a quirk
SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400 is introduced to
enable the use of capabilities register reserved bit-63
to indicate HS400 support.
Because HS400 is non-standard for SDHCI, it is possible
that different vendors will do things in different ways.
However HS200 support faced the same issue but currently
there is only one solution. As such, no attempt has
been made to provide for alternate HS400 solutions except
for SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400.

Basically, some (radeon) adapters have issues with MSI addresses above

listed a specific revision of an adapter that we shipped with our

distros enable nowadays.
So we made the quirk generic and fixed both the graphic and audio
drivers properly to use it.
Without that, ppc64 server machines will crash at boot with a radeon

Since pNFS filelayout can invoke rpc_count_iostats() on another

This time, a very pull request with 216 non-merge

sparse or coccinelle fixes ranging from missing
'static' to returning 0 in case of errors.
More importantly, we have the removal the now
unnecessary 'driver' argument to ->udc_stop().
DWC2 learned about Dual-Role builds. Users of
this IP can now have a single driver built for
host and device roles.
DWC3 got support for two new HW platforms: Exynos7
and AMD.
The Broadcom USB 3.0 Device Controller IP is now
supported and so is PLX USB338x, which means DWC3
has lost is badge as the only USB 3.0 peripheral
IP supported on Linux.
Thanks for Tony Lindgren's work, we can now have
a distro-like kernel where all MUSB glue layers
can be built into the same kernel (statically
or dynamically linked) and it'll work in PIO (DMA
will come probably on v3.20).
Other than these, the usual set of cleanups and
