The function is not called outside soc-dapm.c so there is no need for it
to be exported.

Now that every DAI has a component we can track the DAIs on a per component
basis. This simplifies the DAI lookup when we are only interested in DAIs of a
specific component and also makes it possible to have multiple components with
the same parent device and also register DAIs.

In order to allow other uses of the blkcipher walk API than the blkcipher
algos themselves, this patch copies some of the transform data members to the
walk struct so the transform is only accessed at walk init time.

security_xfrm_policy_alloc can be called in atomic context so the
allocation should be done with GFP_ATOMIC. Add an argument to let the
callers choose the appropriate way. In order to do so a gfp argument
needs to be added to the method xfrm_policy_alloc_security in struct
security_operations and to the internal function
selinux_xfrm_alloc_user. After that switch to GFP_ATOMIC in the atomic
callers and leave GFP_KERNEL as before for the rest.
The path that needed the gfp argument addition is:
security_xfrm_policy_alloc -> security_ops.xfrm_policy_alloc_security ->
all users of xfrm_policy_alloc_security (e.g. selinux_xfrm_policy_alloc) ->
selinux_xfrm_alloc_user (here the allocation used to be GFP_KERNEL only)
Now adding a gfp argument to selinux_xfrm_alloc_user requires us to also
add it to security_context_to_sid which is used inside and prior to this
patch did only GFP_KERNEL allocation. So add gfp argument to
security_context_to_sid and adjust all of its callers as well.

Pull ARM SoC fixes from from Olof Johansson:
"A collection of fixes for ARM platforms. A little large due to us
missing to do one last week, but there's nothing in particular here
that is in itself large and scary.
Mostly a handful of smaller fixes all over the place. The majority is
made up of fixes for OMAP, but there are a few for others as well. In
particular, there was a decision to rename a binding for the Broadcom
pinctrl block that we need to go in before the final release since we
then treat it as ABI"

The connection signature resolving key (CSRK) is used for attribute
protocol signed write procedures. This change generates a new local
key during pairing and requests the peer key as well.
Newly generated key and received key will be provided to userspace
using the New Signature Resolving Key management event.
The Master CSRK can be used for verification of remote signed write
PDUs and the Slave CSRK can be used for sending signed write PDUs
to the remote device.

This patch adds device_reset_optional and (devm_)reset_control_get_optional
variants that drivers can use to indicate they can function without control
over the reset line. For those functions, stubs are added so the drivers can
be compiled with CONFIG_RESET_CONTROLLER disabled.
Also, device_reset is annotated with __must_check. Drivers ignoring the return
value should use device_reset_optional instead.

While implementing atomic_write_len, 4d3773c4bb41 ("kernfs: implement
kernfs_ops->atomic_write_len") moved data copy from userland inside
kernfs_get_active() and kernfs_open_file->mutex so that
kernfs_ops->atomic_write_len can be accessed before copying buffer
from userland; unfortunately, this could lead to locking order
inversion involving mmap_sem if copy_from_user() takes a page fault.

Pull workqueue fix from Tejun Heo:
"This pull request contains a workqueue usage fix for firewire.
For quite a long time now, workqueue only treats two work items
identical iff both their addresses and callbacks match. This is to
avoid introducing false dependency through the work item being
recycled while being executed. This changes non-reentrancy guarantee
for the users of PREPARE[_DELAYED]_WORK() - if the function changes,
reentrancy isn't guaranteed against the previous instance. Firewire
depended on such nonreentrancy guarantee.
This is fixed by doing the work item multiplexing from firewire proper
while keeping the work function unchanged"

and it was taught about the new generic phy layer.
MUSB on AM335x now supports isochronous transfers thanks to

Function FS got a much needed fix to ffs_epfile_io() which was
copying too much data to userspace in some cases.
The printer gadget got a fix for a possible deadlock and plugged
a memory leak.
Ethernet drivers now use NAPI for RX which gives improved throughput.
Other than that, the usual miscelaneous fixes, cleanups, and

Pull tracing fix from Steven Rostedt:
"In the past, I've had lots of reports about trace events not working.
Developers would say they put a trace_printk() before and after the
trace event but when they enable it (and the trace event said it was
enabled) they would see the trace_printks but not the trace event.
I was not able to reproduce this, but that's because I wasn't looking
at the right location. Recently, another bug came up that showed the
issue.
If your kernel supports signed modules but allows for non-signed
modules to be loaded, then when one is, the kernel will silently set
the MODULE_FORCED taint on the module. Although, this taint happens
without the need for insmod --force or anything of the kind, it labels
the module with that taint anyway.
If this tainted module has tracepoints, the tracepoints will be
ignored because of the MODULE_FORCED taint. But no error message will
be displayed. Worse yet, the event infrastructure will still be
created letting users enable the trace event represented by the
tracepoint, although that event will never actually be enabled. This
is because the tracepoint infrastructure allows for non-existing
tracepoints to be enabled for new modules to arrive and have their
tracepoints set.
Although there are several things wrong with the above, this change
only addresses the creation of the trace event files for tracepoints
that are not created when a module is loaded and is tainted. This
change will print an error message about the module being tainted and
not the trace events will not be created, and it does not create the
trace event infrastructure"

Russell writes:
This set of changes reorganises imx-drm's DT bindings by re-using the OF
graph parsing code which was located in drivers/media, removing the
temporary bindings.
The result is that more TODO entries are now removed. While we're not
quite done with this yet as there's a few straggling updates to imx-ldb
to come, but leaving these out is not detrimental at this point in time
- they are more an enhancement.
However, this pull has the additional complication that we're sharing
seven commits with Mauro's V4L git tree, which move the OF graph parsing
code out of drivers/media into drivers/of. Philipp's imx-drm changes
depend on these and my previously committed round of imx-drm commits.
Hence, the diffstat below is from a test merge with your tree head
(17b02809cfa7).
Mauro merged those seven commits earlier today as a git pull, so both
trees will be sharing exactly the same commit IDs.
I've given these changes a spin here on both my Hummingboard and Cubox-i4
(one is iMX6Solo, the other is iMX6Quad based), which includes Xorg using
the DRM device directly, and I find nothing wrong.
The diffstat does look a little scarey - this is because we're having to
update the ARM DT files along with this change, and obviously the
dependency on the OF graph parsing code.

This commit takes care of the generated signature error CQE generated
by the HW (if happened). The underlying mlx5 driver will handle
signature error completions and will mark the relevant memory region
as dirty.
Once the consumer gets the completion for the transaction, it must
check for signature errors on signature memory region using a new
lightweight verb ib_check_mr_status().
In case the user doesn't check for signature error (i.e. doesn't call
ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the
memory region cannot be used for another signature operation
(REG_SIG_MR work request will fail).

This patch implements IB_WR_REG_SIG_MR posted by the user.
Baisically this WR involves 3 WQEs in order to prepare and properly
register the signature layout:
1. post UMR WR to register the sig_mr in one of two possible ways:
* In case the user registered a single MR for data so the UMR data segment
consists of:
- single klm (data MR) passed by the user
- BSF with signature attributes requested by the user.
* In case the user registered 2 MRs, one for data and one for protection,
the UMR consists of:
- strided block format which includes data and protection MRs and
their repetitive block format.
- BSF with signature attributes requested by the user.
2. post SET_PSV in order to set the memory domain initial
signature parameters passed by the user.
SET_PSV is not signaled and solicited CQE.
3. post SET_PSV in order to set the wire domain initial
signature parameters passed by the user.
SET_PSV is not signaled and solicited CQE.
* After this compound WR we place a small fence for next WR to come.
This patch also introduces some helper functions to set the BSF correctly
and determining the signature format selectors.

Support create_mr and destroy_mr verbs. Creating ib_mr may be done
for either ib_mr that will register regular page lists like
alloc_fast_reg_mr routine, or indirect ib_mrs that can register other
(pre-registered) ib_mrs in an indirect manner.
In addition user may request signature enable, that will mean that the
created ib_mr may be attached with signature attributes (BSF, PSVs).
Currently we only allow direct/indirect registration modes.

Introduce a verbs interface for signature-related operations. A
signature handover operation configures the layouts of data and
protection attributes both in memory and wire domains.
Signature operations are:
- INSERT:
Generate and insert protection information when handing over
data from input space to output space.
- validate and STRIP:
Validate protection information and remove it when handing over
data from input space to output space.
- validate and PASS:
Validate protection information and pass it when handing over
data from input space to output space.
Once the signature handover opration is done, the HCA will offload
data integrity generation/validation while performing the actual data
transfer.
Additions:
1. HCA signature capabilities in device attributes
Verbs provider supporting signature handover operations fills
relevant fields in device attributes structure returned by
ib_query_device.
2. QP creation flag IB_QP_CREATE_SIGNATURE_EN
Creating a QP that will carry signature handover operations may
require some special preparations from the verbs provider. So we
add QP creation flag IB_QP_CREATE_SIGNATURE_EN to declare that the
created QP may carry out signature handover operations. Expose
signature support to verbs layer (no support for now).
3. New send work request IB_WR_REG_SIG_MR
Signature handover work request. This WR will define the signature
handover properties of the memory/wire domains as well as the
domains layout. The purpose of this work request is to bind all
the needed information for the signature operation:
- data to be transferred: wr->sg_list (ib_sge).
* The raw data, pre-registered to a single MR (normally, before
signature, this MR would have been used directly for the data
transfer)
- data protection guards: sig_handover.prot (ib_sge).
* The data protection buffer, pre-registered to a single MR, which
contains the data integrity guards of the raw data blocks.
Note that it may not always exist, only in cases where the user is
interested in storing protection guards in memory.
- signature operation attributes: sig_handover.sig_attrs.
* Tells the HCA how to validate/generate the protection information.
Once the work request is executed, the memory region that will
describe the signature transaction will be the sig_mr. The
application can now go ahead and send the sig_mr.rkey or use the
sig_mr.lkey for data transfer.
4. New Verb ib_check_mr_status
check_mr_status verb checks the status of the memory region post
transaction. The first check that may be used is
IB_MR_CHECK_SIG_STATUS, which will indicate if any signature
errors are pending for a specific signature-enabled ib_mr. This
verb is a lightwight check and is allowed to be taken from
interrupt context. An application must call this verb after it is
known that the actual data transfer has finished.

This commit introduces verbs for creating/destoying memory
regions which will allow new types of memory key operations such
as protected memory registration.
Indirect memory registration is registering several (one
of more) pre-registered memory regions in a specific layout.
The Indirect region may potentialy describe several regions
and some repitition format between them.
Protected Memory registration is registering a memory region
with various data integrity attributes which will describe protection
schemes that will be handled by the HCA in an offloaded manner.
These memory regions will be applicable for a new REG_SIG_MR
work request introduced later in this patchset.
In the future these routines may replace or implement current memory
regions creation routines existing today:
- ib_reg_user_mr
- ib_alloc_fast_reg_mr
- ib_get_dma_mr
- ib_dereg_mr

Peter Hurley noticed that since a2c1c57be8d9 ("workqueue: consider
work function when searching for busy work items"), a work item which
gets assigned a different work function would break out of the
non-reentrancy guarantee as workqueue would consider it a different
work item.
This is fragile and extremely subtle. PREPARE_[DELAYED_]WORK() have
never been used widely and its semantics has always been somewhat
iffy. If the work item is known not to be on queue when
PREPARE_WORK() is called, there's no difference from using
INIT_WORK(). If the work item may be queued at the time of
PREPARE_WORK(), we can't really tell whether the old or new function
will be executed the next time.
We really don't want this level of subtlety in workqueue interface for
such marginal use cases. The previous patches converted all existing
users away from PREPARE_[DELAYED_]WORK(). Let's remove them.

PREPARE_[DELAYED_]WORK() are being phased out. They have few users
and a nasty surprise in terms of reentrancy guarantee as workqueue
considers work items to be different if they don't have the same work
function.
nvme_dev->reset_work is multiplexed with multiple work functions.
Introduce nvme_reset_workfn() which invokes nvme_dev->reset_workfn and
always use it as the work function and update the users to set the
->reset_workfn field instead of overriding the work function using
PREPARE_WORK().
It would probably be best to route this with other related updates
through the workqueue tree.
Compile tested.
