alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.
The workqueue "workq" queues work item &skb_work. It has been
identity converted.
WQ_MEM_RECLAIM has been set to ensure forward progress under

The workqueue "addr_wq" queues a single work item &work and hence
doesn't require ordering. Also, it is being used on a memory reclaim
path. Hence, it has been converted to use alloc_workqueue with
WQ_MEM_RECLAIM set.
WQ_MEM_RECLAIM has been set to ensure forward progress under

When LAG is active, port up/down events should be triggered
by tracking the LAG master, and not one of the two slave
netdevs.
In the same manner, ib_query_port() should return the details
of the LAG master.

This is done in two steps:
1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from
both ports arriving on PF0 root flowtable, so we will be able to catch
all raw-eth traffic on PF0.
2) Creation of LAG demux flowtable in order to direct all non-raw-eth
traffic back to its source port, assuring that normal Ethernet
traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port
state, it makes sense to propagate the port up/down events to ib_core
when the netdev port state changes, instead of relying on traditional
core events.
This also keeps both the event and ib_query_port() synchronized.

Flow steering specifications structures were implemented as in an
extensible way that allows one to add new filters and new fields
to existing filters.
These specifications have never been extended, therefore the
kernel flow specifications size and the user flow specifications size
were must to be equal.
In downstream patch, the IPv4 flow specifications type is extended to
support TOS and TTL fields.
To support an extension we change the flow specifications size
condition test to be as following:
* If the user flow specifications is bigger than the kernel
specifications, we verify that all the bits which not in the kernel
specifications are zeros and the flow is added only with the kernel
specifications fields.
* Otherwise, we add flow rule only with the user specifications fields.
User space filters must be aligned with 32bits.

- Bit mask of the supported RX fields that can participate

Pull SCSI updates from James Bottomley:
"This update includes the usual round of major driver updates (hpsa,
be2iscsi, hisi_sas, zfcp, cxlflash). There's a new incarnation of hpsa
called smartpqi for which a driver is added, there's some cleanup work
of the ibm vscsi target and updates to libfc, plus a whole host of
minor fixes and updates and finally the removal of several ISA drivers
which seem not to have been used for years"

Increase the initial kernel default page mapping size for SMP kernels to 32MB
and add a runtime check which panics early if the kernel is bigger than the
initial mapping size.
This fixes boot crashes of 32bit SMP kernels. Due to the introduction of huge
page support in kernel 4.4 and it's required initial kernel layout in memory, a
32bit SMP kernel usually got bigger (in layout, not size) than 16MB.

Similar to BLK regions, publish new seed namespace devices to allow
unused PMEM region capacity to be consumed by additional namespaces.

Short-circuit doomed-to-fail label validation attempts by skipping
labels that are outside the given region. For example a DIMM that has
multiple PMEM regions will waste time attempting to create namespaces
only to find that the interleave-set-cookie does not validate, e.g.:
nd_region region6: invalid cookie in label: 73e608dc-47b9-4b2a-b5c7-2d55a32e0c2
Similar to how we skip BLK labels when performing PMEM validation we can
skip out-of-range labels early.

Now that we have nd_region_available_dpa() able to handle the presence
of multiple PMEM allocations in aliased PMEM regions, reuse that same
infrastructure to track allocations from free space. In particular
handle allocating from an aliased PMEM region in the case where there
are dis-contiguous holes. The allocation for BLK and PMEM are
documented in the space_valid() helper:
BLK-space is valid as long as it does not precede a PMEM
allocation in a given region. PMEM-space must be contiguous
and adjacent to an existing existing allocation (if one
exists).

Instead of assuming that there will only ever be one allocated range at
the start of the region, account for additional namespaces that might
start at an offset from the region base.
After this change pmem namespaces now have a reason to carry an array of
resources similar to blk. Unifying the resource tracking infrastructure
in nd_namespace_common is a future cleanup candidate.

The free dpa (dimm-physical-address) space calculation reports how much
free space is available with consideration for aliased BLK + PMEM
regions. Recall that BLK capacity is allocated from high addresses and
PMEM is allocated from low addresses in their respective regions.
nd_region_available_dpa() accounts for the fact that the largest
encroachment (lowest starting address) into PMEM capacity by a BLK
allocation limits the available capacity to that point, regardless if
there is BLK allocation hole at a higher address. Similarly, for the
multi-pmem case we need to track the largest encroachment (highest
ending address) of a PMEM allocation in BLK capacity regardless of
whether there is an allocation hole that a BLK allocation could fill at
a lower address.

If label scanning finds multiple valid pmem namespaces allow them to be
surfaced rather than fail namespace scanning. Support for creating
multiple namespaces per region is saved for a later patch.
Note that this adds some new error messages to clarify which of the pmem
namespaces in the set are potentially impacted by invalid labels.

Update nfit_test to handle multiple sub-allocations within a given pmem
region. The mock resource now tracks and un-tracks sub-ranges as they
are requested and released (either explicitly or via devm callback).
