In the function hfi1_create_ctxts the array "dd->rcd" is allocated and
then populated with allocated resources in a loop. Previously, if
error happened during the loop, only resource allocated in the current
iteration would be freed. The array itself would then be freed, leaving
the resources that were allocated in previous iterations and referenced
by the array elements in limbo.
This patch makes sure all allocated resources are freed before freeing
the array "dd->rcd". Also the resource allocation now takes account of
the numa node the device is attached to.

This patch fixes an Oops on device unbind, when the device is used
by a PSM user process. PSM processes access device resources which
are freed on device removal. Similar protection exists in uverbs
in ib_core for Verbs clients, but PSM doesn't use ib_uverbs hence
a separate protection is required for PSM clients.

The initial code for rdmavt carried with it a restriction that was a
vestige from the qib driver, that to dma map a page it had to be less
than a page size. This is not the case on modern hardware, both qib and
hfi1 will be just fine with unaligned map requests.
This fixes a 4.8 regression where by an IPoIB transfer of > PAGE_SIZE
will hang because the dma map page call always fails. This was
introduced after commit 5faba5469522 ("IB/ipoib: Report SG feature
regardless of HW UD CSUM capability") added the capability to use SG by
default. Rather than override this, the HW supports it, so allow SG.

Pull tracing fixes from Steven Rostedt:
"Alexei discovered a race condition in modules failing to load that can
cause a ftrace check to trigger and disable ftrace.
This is because of the way modules are registered to ftrace. Their
functions are loaded in the ftrace function tables but set to
"disabled" since they are still in the process of being loaded by the
module. After the module is finished, it calls back into the ftrace
infrastructure to enable it.
Looking deeper into the locations that access all the functions in the
table, I found more locations that should ignore the disabled ones"

When locking a GPIO line as IRQ, we go to lengths to
double-check that the line is really set as input before
marking it as used for IRQ. This is not good on GPIO chips
that can sleep, because this function is called in IRQ-safe
context. Just skip this if it can't be checked quickly.
Currently this happens on sleeping expanders such as STMPE
or TC3589x:

The tile architecture already marks RO_DATA as read-only in
the kernel, so grouping RO_AFTER_INIT_DATA with RO_DATA, as is
done by default, means the kernel faults in init when it tries
to write to RO_AFTER_INIT_DATA. For now, just arrange that
__ro_after_init is handled like __write_once, i.e. __read_mostly.

Since commit b45f64d16d45 ("mlxsw: spectrum_router: Use FIB notifications
instead of switchdev calls") we reflect to the device the entire FIB
table and not only FIBs that point to netdevs created by the driver.
During module removal, FIBs of the second type are removed following
NETDEV_UNREGISTER events sent. The other FIBs are still present in both
the driver's cache and the device's table.
Fix this by iterating over all the FIB tables in the device and flush
them. There's no need to take locks, as we're the only writer.

Commit 52f95bbfcf72 ("stmmac: fix adjust link call in case of a switch
is attached") added some logic to avoid polling the fixed PHY and
therefore invoking the adjust_link callback more than once, since this
is a fixed PHY and link events won't be generated.
This works fine the first time, because we start with phydev->irq =
PHY_POLL, so we call adjust_link, then we set phydev->irq =
PHY_IGNORE_INTERRUPT and we stop polling the PHY.
Now, if we called ndo_close(), which calls both phy_stop() and does an
explicit netif_carrier_off(), we end up with a link down. Upon calling
ndo_open() again, despite starting the PHY state machine, we have
PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the
link is permanently down.

When a module is first loaded and its function ip records are added to the
ftrace list of functions to modify, they are set to DISABLED, as their text
is still in a read only state. When the module is fully loaded, and can be
updated, the flag is cleared, and if their's any functions that should be
tracing them, it is updated at that moment.
But there's several locations that do record accounting and should ignore
records that are marked as disabled, or they can cause issues.
Alexei already fixed one location, but others need to be addressed.

ftrace_shutdown() checks for sanity of ftrace records
and if dyn_ftrace->flags is not zero, it will warn.
It can happen that 'flags' are set to FTRACE_FL_DISABLED at this point,
since some module was loaded, but before ftrace_module_enable()
cleared the flags for this module.
In other words the module.c is doing:
ftrace_module_init(mod); // calls ftrace_update_code() that sets flags=FTRACE_FL_DISABLED
... // here ftrace_shutdown() is called that warns, since
err = prepare_coming_module(mod); // didn't have a chance to clear FTRACE_FL_DISABLED
Fix it by ignoring disabled records.
It's similar to what __ftrace_hash_rec_update() is already doing.

Now when users shutdown a sock with SEND_SHUTDOWN in sctp, even if
this sock has no connection (assoc), sk state would be changed to
SCTP_SS_CLOSING, which is not as we expect.
Besides, after that if users try to listen on this sock, kernel
could even panic when it dereference sctp_sk(sk)->bind_hash in
sctp_inet_listen, as bind_hash is null when sock has no assoc.
This patch is to move sk state change after checking sk assocs
is not empty, and also merge these two if() conditions and reduce
indent level.

bnx2: Wait for in-flight DMA to complete at probe stage
This is v2 post.
In commit 3e1be7a ("bnx2: Reset device during driver initialization"),
firmware requesting code was moved from open stage to probe stage.
The reason is in kdump kernel hardware iommu need device be reset in
driver probe stage, otherwise those in-flight DMA from 1st kernel
will continue going and look up into the newly created io-page tables.
However bnx2 chip resetting involves firmware requesting issue, that
need be done in open stage.
Michale Chan suggested we can just wait for the old in-flight DMA to
complete at probe stage, then though without device resetting, we
don't need to worry the old in-flight DMA could continue looking up
the newly created io-page tables.
v1->v2:
Michael suggested to wait for the in-flight DMA to complete at probe
stage. So give up the old method of trying to reset chip at probe
stage, take the new way accordingly.

It's the code trying to clear drvdata of the assigned usb_device where
the usb_device itself was already released in usb_release_dev() after
the disconnect callback.
This patch fixes it by checking whether the code path is via the
disconnect callback, i.e. chip->shutdown flag is set.

In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data
usage") the stream specific information initialization was broken, with
the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.
Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc(). When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

This reverts commit bfd8d3f23b51018388be0411ccbc2d56277fe294.
It turns out that this flushes things much too aggressiverly, and causes
lines to break up when the system logger races with new continuation
lines being printed.
There's a pending patch to make printk() flushing much more
straightforward, but it's too invasive for 4.9, so in the meantime let's
just not make the system message logging flush continuation lines.
They'll be flushed by the final newline anyway.

This file was converted to a separate module at commit 7a0786c19d65
("gp8psk: Fix DVB frontend attach"), because the DVB attach routines
require it to work. However, I forgot to copy the MODULE_foo() macros
from the original module, causing this warning:

draining the qp right after disconnect might not suffice because
the nvmet sq is not fully drained (in nvmet_sq_destroy) and we might
see completions after the drain. Instead, drain right before the
qp destroy which comes after the sq destruction and we can be sure
that no posts come after the drain.

While testing nvme-rdma with the spdk nvmf target over iw_cxgb4, I
configured the target (mistakenly) to generate an error creating the
NVMF IO queues. This resulted a "Invalid SQE Parameter" error sent back
to the host on the first IO queue connect:
[ 9610.928182] nvme nvme1: queue_size 128 > ctrl maxcmd 120, clamping down
[ 9610.938745] nvme nvme1: creating 32 I/O queues.
So nvmf_connect_io_queue() returns an error to
nvmf_connect_io_queue() / nvmf_connect_io_queues(), and that
is returned to nvme_rdma_create_io_queues(). In the error path,
nvmf_rdma_create_io_queues() frees the queue tagset memory _before_
stopping and freeing the IB queues, which causes yet another
touch-after-free crash due to SQ CQEs being flushed after the ib_cqe
structs pointed-to by the flushed WRs have been freed (since they are
part of the nvme_rdma_request struct).
The fix is to stop and free the queues in nvmf_connect_io_queues()
if there is an error connecting any of the queues.

In case we accepted a queue connection and it failed, we might not
remove the queue from the list until we unload and clean it up.
We should delete it from the queue list on the relevant handler.

In the transport, in case of an interal queue error like
error completion in rdma we trigger a fatal error. However,
multiple queues in the same controller can serr error completions
and we don't want to trigger fatal error work more than once.

If we reconncect we might have command queue up that get resent as soon
as the queue is restarted. But until the connect command succeeded we
can't send other command. Add a new flag that marks a queue as live when
connect finishes, and delay any non-connect command until the queue is
live based on it.
