2205369a31 vlan: Fix header ops passthru when doing TX VLAN offload.
When the vlan code detects that the real device can do TX VLAN offloads
in hardware, it tries to arrange for the real device's header_ops to
be invoked directly.

But it does so illegally, by simply hooking the real device's
header_ops up to the VLAN device.

This doesn't work because we will end up invoking a set of header_ops
routines which expect a device type which matches the real device, but
will see a VLAN device instead.

Fix this by providing a pass-thru set of header_ops which will arrange
to pass the proper real device instead.

To facilitate this add a dev_rebuild_header().  There are
implementations which provide a ->cache and ->create but not a
->rebuild (f.e. PLIP).  So we need a helper function just like
dev_hard_header() to avoid crashes.

Use this helper in the one existing place where the
header_ops->rebuild was being invoked, the neighbour code.

With lots of help from Florian Westphal.

f18650ace3 crush: apply chooseleaf_tries to firstn mode too
Parameterize the attempts for the _firstn choose method, and apply the
rule-specified tries count to firstn mode as well.  Note that we have
slightly different behavior here than with indep:

 If the firstn value is not specified for firstn, we pass through the
 normal attempt count.  This maintains compatibility with legacy behavior.
 Note that this is usually *not* actually N^2 work, though, because of the
 descend_once tunable.  However, descend_once is unfortunately *not* the
 same thing as 1 chooseleaf try because it is only checked on a reject but
 not on a collision.  Sigh.

 In contrast, for indep, if tries is not specified we default to 1
 recursive attempt, because that is simply more sane, and we have the
 option to do so.  The descend_once tunable has no effect for indep.

be3226acc5 crush: new SET_CHOOSE_LEAF_TRIES command
Explicitly control the number of sample attempts, and allow the number of
tries in the recursive call to be explicitly controlled via the rule. This
is important because the amount of time we want to spend looking for a
solution may be rule dependent (e.g., higher for the wide indep pool than
the rep pools).

(We should do the same for the other tunables, by the way!)

Pull networking fixes from David Miller:
 "Some holiday bug fixes for 3.13...  There is still one bug I'd like to
  get fixed before 3.13-final.

  The vlan code erroneously assignes the header ops of the underlying
  real device to the VLAN device above it when the real device can
  hardware offload VLAN handling.  That's completely bogus because
  header ops are tied to the device type, so they only expect to see a
  'dev' argument compatible with their ops.

  The fix is the have the VLAN code use a special set of header ops that
  does the pass-thru correctly, by calling the underlying real device's
  header ops but _also_ passing in the real device instead of the VLAN
  device.

  That fix is currently waiting some testing.

Almost every function in include/linux/iommu.h has an empty stub

This adds an empty stub for iommu_group_get_by_id() for IOMMU_API

caa73ea158 ACPI / hotplug / driver core: Handle containers in a special way
ACPI container devices require special hotplug handling, at least
on some systems, since generally user space needs to carry out
system-specific cleanup before it makes sense to offline devices in
the container.  However, the current ACPI hotplug code for containers
first attempts to offline devices in the container and only then it
notifies user space of the container offline.

Moreover, after commit 202317a573 (ACPI / scan: Add acpi_device
objects for all device nodes in the namespace), ACPI device objects
representing containers are present as long as the ACPI namespace
nodes corresponding to them are present, which may be forever, even
if the container devices are physically detached from the system (the
return values of the corresponding _STA methods change in those
cases, but generally the namespace nodes themselves are still there).
Thus it is useful to introduce entities representing containers that
will go away during container hot-unplug.

The goal of this change is to address both the above issues.

The idea is to create a "companion" container system device for each
of the ACPI container device objects during the initial namespace
scan or on a hotplug event making the container present.  That system
device will be unregistered on container removal.  A new bus type
for container devices is added for this purpose, because device
offline and online operations need to be defined for them.  The
online operation is a trivial function that is always successful
and the offline uses a callback pointed to by the container device's
offline member.

For ACPI containers that callback simply walks the list of ACPI
device objects right below the container object (its children) and
checks if all of their physical companion devices are offline.  If
that's not the case, it returns -EBUSY and the container system
devivce cannot be put offline.  Consequently, to put the container
system device offline, it is necessary to put all of the physical
devices depending on its ACPI companion object offline beforehand.

Container system devices created for ACPI container objects are
initially online.  They are created by the container ACPI scan
handler whose hotplug.demand_offline flag is set.  That causes
acpi_scan_hot_remove() to check if the companion container system
device is offline before attempting to remove an ACPI container or
any devices below it.  If the check fails, a KOBJ_CHANGE uevent is
emitted for the container system device in question and user space
is expected to offline all devices below the container and the
container itself in response to it.  Then, user space can finalize
the removal of the container with the help of its ACPI device
object's eject attribute in sysfs.

ARM: tegra: powergate driver changes

This branch includes all the changes to Tegra's powergate driver for 3.14.
These are separate out, since the Tegra DRM changes for 3.14 rely on the
new APIs introduced here.

A few cleanups and fixes are included, plus additions of Tegra124 SoC
support, and a new API for manipulating Tegra's IO rail deep power down
states.

This branch is based on tag tegra-for-3.14-dmas-resets-rework, in order
to avoid conflicts with the addition of common reset controller support
to the powergate driver.

From Stephen Warren:
ARM: tegra: implement common DMA and resets DT bindings

This series converts the Tegra DTs and drivers to use the common/
standard DMA and reset bindings, rather than custom bindings. It also
adds complete documentation for the Tegra clock bindings without
actually changing any binding definitions.

This conversion relies on a few sets of patches in branches from outside
the Tegra tree:

1) A patch to add an DMA channel request API which allows deferred probe
   to be implemented.

2) A patch to implement a common part of the of_xlate function for DMA
   controllers.

3) Some ASoC patches (which in turn rely on (1) above), which support
   deferred probe during DMA channel allocation.

4) The Tegra clock driver changes for 3.14.

Consequently, this branch is based on a merge of all of those external
branches.

In turn, this branch is or will be pulled into a few places that either
rely on features introduced here, or would otherwise conflict with the
patches:

a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
   conflicts.

b) The DRM tree, which introduces new code that relies on the reset
   controller framework introduced in this branch, and to avoid
   conflicts.
