This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
hisi_sas, smartpqi, megaraid_sas, arcmsr. In addition, with the
continuing absence of Nic we have target updates for tcmu and target
core (all with reviews and acks). The biggest observable change is
going to be that we're (again) trying to switch to mulitqueue as the
default (a user can still override the setting on the kernel command
line). Other major core stuff is the removal of the remaining
Microchannel drivers, an update of the internal timers and some
reworks of completion and result handling.

Rename target_alloc_session to target_setup_session to avoid confusion with
the other transport session allocation function that only allocates the
session and because the target_alloc_session does so much more. It
allocates the session, sets up the nacl and registers the session.
The next patch will then add a remove function to match the setup in this
one, so it should make sense for all drivers, except iscsi, to just call
those 2 functions to setup and remove a session.
iscsi will continue to be the odd driver.

The commit cited below checked that the port numbers provided in the
primary and alt AVs are legal.
That is sufficient to prevent a kernel panic. However, it is not
sufficient for correct operation.
In Linux, AVs (both primary and alt) must be completely self-described.
We do not accept an AV from userspace without an embedded port number.
(This has been the case since kernel 3.14 commit dbf727de74
("IB/core: Use GID table in AH creation and dmac resolution")).
For the primary AV, this embedded port number must match the port number
specified with IB_QP_PORT.
We also expect the port number embedded in the alt AV to match the

Convert all users of struct acpi_reference_args to more generic
fwnode_reference_args. This will
1) avoid an ACPI specific references to device nodes with integer
arguments as well as
2) allow making references to nodes other than device nodes in ACPI.
As a by-product, convert the fwnode interger arguments to u64. The
arguments were 64-bit integers on ACPI but the fwnode arguments were
just 32-bit.

The conversion from offsetof() calculations to sizeof()

In such scenario we got "create flow failed, flow 10: 8 bytes

Flows can be created on UD and RAW_PACKET QP types. Attempts to provide
other QP types as an input causes to various unpredictable failures.
The reason is that in order to support all various types (e.g. XRC), we
are supposed to use real_qp handle and not qp handle and expect to
driver/FW to fail such (XRC) flows. The simpler and safer variant is to
ban all QP types except UD and RAW_PACKET, instead of relying on
driver/FW.

While __atomic_add_unless() was originally intended as a building-block
for atomic_add_unless(), it's now used in a number of places around the
kernel. It's the only common atomic operation named __atomic*(), rather
than atomic_*(), and for consistency it would be better named
atomic_fetch_add_unless().
This lack of consistency is slightly confusing, and gets in the way of
scripting atomics. Given that, let's clean things up and promote it to
an official part of the atomics API, in the form of
atomic_fetch_add_unless().
This patch converts definitions and invocations over to the new name,
including the instrumented version, using the following script:
----
git grep -w __atomic_add_unless | while read line; do
sed -i '{s/\<__atomic_add_unless\>/atomic_fetch_add_unless/}' "${line%%:*}";
done
git grep -w __arch_atomic_add_unless | while read line; do
sed -i '{s/\<__arch_atomic_add_unless\>/arch_atomic_fetch_add_unless/}' "${line%%:*}";
done
----
Note that we do not have atomic{64,_long}_fetch_add_unless(), which will
be introduced by later patches.
There should be no functional change as a result of this patch.

In rxe_send, when network_type is not RDMA_NETWORK_IPV4 or
RDMA_NETWORK_IPV6, skb is freed and -EINVAL is returned.
Then rxe_xmit_packet will return -EINVAL, too. In rxe_requester,
this skb is double freed.
In rxe_requester, kfree_skb is needed only after fill_packet fails.
So kfree_skb is moved from label err to test fill_packet.
Fixes: 5793b46521 ("IB/rxe: remove unnecessary skb_clone in xmit")

This has been a quiet cycle for RDMA, the big bulk is the usual smallish
driver updates and bug fixes. About four new uAPI related things. Not as much
Szykaller patches this time, the bugs it finds are getting harder to fix.
- More work cleaning up the RDMA CM code
- Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns, i40iw, iw_cxgb4, mlx5, rxe
- Driver specific resource tracking and reporting via netlink
- Continued work for name space support from Parav
- MPLS support for the verbs flow steering uAPI
- A few tricky IPoIB fixes improving robustness
- HFI1 driver support for the '16B' management packet format
- Some auditing to not print kernel pointers via %llx or similar
- Mark the entire 'UCM' user-space interface as BROKEN with the intent to remove it
entirely. The user space side of this was long ago replaced with RDMA-CM and
syzkaller is finding bugs in the residual UCM interface nobody wishes to fix because
nobody uses it.
- Purge more bogus BUG_ON's from Leon
- 'flow counters' verbs uAPI
- T10 fixups for iser/isert, these are Acked by Martin but going through the RDMA
tree due to dependencies
