The length field value of non-array string properties is the length of the
string itself. Non-array string properties thus require specific handling.
Fix this.

Similar to OF endpoints, endpoint type nodes can be also supported on
ACPI. In order to make it possible for drivers to ignore the matter,
add a type for fwnode_endpoint and a function to parse them.
On ACPI, find the child node index instead of relying on the "endpoint"
property.

DT has had concept of remote endpoints for some time already. It makes
possible to reference another firmware node through a property called
remote-endpoint. This is already used by some subsystems like v4l2 for
parsing hardware properties related to camera.
This patch adds ACPI support for remote endpoints utilizing _DSD
hierarchical data extensions.

Since now we have means to enumerate all children of any fwnode even in
ACPI we can implement fwnode_get_named_child_node(). This is similar than
device_get_named_child_node() with the exception that it can be called to
any fwnode handle. Make device_get_named_child_node() call directly this
new function.
This is useful in cases where we need to be able to find child nodes which
are not direct descendants of the parent device.

The ACPI _DSD hierarchical data extension makes it possible to have
hierarchies deeper than one level in similar way than DT allows. These
"subsubnodes" have not been accessible because device property
implementation only provides device_get_next_child_node() that is limited
to direct descendants of a device.
We need this ability in order support things like remote endpoints
currently supported in DT with of_graph_* APIs.
Modify acpi_get_next_subnode() to accept fwnode handle instead and update
callers accordingly. Also add a new function fwnode_get_next_child_node()
that works directly with fwnodes and modify device_get_next_child_node() to
call it directly. While there add a macro fwnode_for_each_child_node()
analogous to the current device_for_each_child_node() but it works with
fwnodes instead of devices.

Sometimes it is useful to be able to navigate firmware node hierarchy
upwards toward parent nodes. ACPI device nodes are pretty much already
supported because ACPICA provides acpi_get_parent(). ACPI data nodes,
however, are all below the same parent ACPI device. Their hierarchy is
created by "linking" each other using references in the value field.
Add parent pointer to the parent data node while we create them so it is
easy to navigate the hierarchy backwards. We use this parent pointer in a
new function acpi_node_get_parent() that is able to extract parent of both
ACPI firmware node types.

Pull rdma fixes from Doug Ledford:
"This has been a slow -rc cycle for the RDMA subsystem. We really
haven't had a lot of rc fixes come in. This pull request is the first
of this entire rc cycle and it has all of the suitable fixes so far
and it's still only about 20 patches. The fix for the minor breakage
cause by the dma mapping patchset is in here, as well as a couple
other potential oops fixes, but the rest is more minor.
Summary:
- fix for dma_ops change in this kernel, resolving the s390, powerpc,
and IOMMU operation
- a few other oops fixes
- the rest are all minor fixes"

"We've got an audit fix, and unfortunately it is big.
While I'm not excited that we need to be sending you something this

This code has passed our testsuite without problem and it has held up

When the rdma device is removed, we must cleanup all
the rdma resources within the DEVICE_REMOVAL event
handler to let the device teardown gracefully. When
this happens with live I/O, some memory regions are
occupied. Thus, track them too and dereg all the mr's.
We are safe with mr access by iscsi_iser_cleanup_task.

This workqueue is used by our storage target mode ULPs
via the new CQ API. Recent observations when working
with very high-end flash storage devices reveal that
UNBOUND workqueue threads can migrate between cpu cores
and even numa nodes (although some numa locality is accounted
for).
While this attribute can be useful in some workloads,
it does not fit in very nicely with the normal
run-to-completion model we usually use in our target-mode
ULPs and the block-mq irq<->cpu affinity facilities.
The whole block-mq concept is that the completion will
land on the same cpu where the submission was performed.
The fact that our submitter thread is migrating cpus
can break this locality.
We assume that as a target mode ULP, we will serve multiple
initiators/clients and we can spread the load enough without
having to use unbound kworkers.
Also, while we're at it, expose this workqueue via sysfs which
is harmless and can be useful for debug.

According to C9-147, MSN should only be incremented when the last packet of
a multi packet request has been received.
"Logically, the requester associates a sequential Send Sequence Number
(SSN) with each WQE posted to the send queue. The SSN bears a one-
to-one relationship to the MSN returned by the responder in each re-
sponse packet. Therefore, when the requester receives a response, it in-
terprets the MSN as representing the SSN of the most recent request
completed by the responder to determine which send WQE(s) can be
completed."

Avoid that the following error message is reported on the console
while loading an RDMA driver with I/O MMU support enabled:
DMAR: Allocating domain for mlx5_0 failed
Ensure that DMA mapping operations that use to_pci_dev() to
access to struct pci_dev see the correct PCI device. E.g. the s390
and powerpc DMA mapping operations use to_pci_dev() even with I/O
MMU support disabled.
This patch preserves the following changes of the DMA mapping updates
patch series:
- Introduction of dma_virt_ops.
- Removal of ib_device.dma_ops.
- Removal of struct ib_dma_mapping_ops.
- Removal of an if-statement from each ib_dma_*() operation.
- IB HW drivers no longer set dma_device directly.

When vmalloc_user is used to create memory that is supposed to be mmap'd
to user space, it is necessary for the mmap cookie (eg the offset) to be
aligned to SHMLBA.
This creates a situation where all virtual mappings of the same physical
page share the same virtual cache index and guarantees VIPT coherence.
Otherwise the cache is non-coherent and the kernel will not see writes
by userspace when reading the shared page (or vice-versa).
