The `dma_map_XXX()` functions can fail and must be checked using
`dma_mapping_error()`. This patch adds proper error handling for all
DMA mapping calls.
In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is
deallocated and marked accordingly.
In `atl1_tx_map()`, previously mapped buffers are unmapped and the
packet is dropped on failure.
If `atl1_xmit_frame()` drops the packet, increment the tx_error counter.

====================
Octeontx2-pf: extend link modes support
This series of patches adds multi advertise mode support along with
other improvements in link mode management code flow.
Patch1: Currently all SGMII modes 10/100/1000baseT are mapped with
single firmware mode. This patch updates these link modes
with corresponding firmware modes.
Patch2: Due to limitation in current kernel <-> firmware communication,
link modes are divided into multiple groups, and identified
with their group index.
Patch3: Adds support for multi advertise mode.

Current implementation considers only first advertise
mode and passes the same to firmware to process.
This patch extends code such that user can advertise
multiple modes on the given interface.
Below are high level changes:
1. Remove unnecessary speed/duplex/autoneg validation as its
already verified as part of "set_link_ksettings"
2. Since scratch csr framework designed to support single mode at a time,
use "shared firmware data" for multi mode support.

To resolve the issue, the unused port field is modified as below
uint64_t reserved2:6;
uint64_t mode_group_idx:2;
'mode_group_idx' categorize the mode ID range to accommodate more modes.
To specify mode ID range of 0 - 41, this field will be 0.
To specify mode ID range of 42 - 83, this field will be 1.
mode ID will be still mentioned as 1 << (0 - 41). But the mode_group_idx

Current implementation maps ethtool link modes 10baseT/100baseT/1000baseT
to single firmware mode SGMII. This create a problem for end users who want
to advertise only one speed among them.
This patch addresses the issue by mapping each ethtool link mode

Arkadiusz Kubalewski says:
====================
dpll: add Reference SYNC feature
The device may support the Reference SYNC feature, which allows the
combination of two inputs into a input pair. In this configuration,
clock signals from both inputs are used to synchronize the DPLL device.
The higher frequency signal is utilized for the loop bandwidth of the DPLL,
while the lower frequency signal is used to syntonize the output signal of
the DPLL device. This feature enables the provision of a high-quality loop
bandwidth signal from an external source.
A capable input provides a list of inputs that can be bound with to create
Reference SYNC. To control this feature, the user must request a
desired state for a target pin: use ``DPLL_PIN_STATE_CONNECTED`` to
enable or ``DPLL_PIN_STATE_DISCONNECTED`` to disable the feature. An input
pin can be bound to only one other pin at any given time.
Verify pins bind state/capabilities:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--do pin-get \
--json '{"id":0}'
{'board-label': 'CVL-SDP22',
'id': 0,
[...]
'reference-sync': [{'id': 1, 'state': 'disconnected'}],
[...]}
Bind the pins by setting connected state between them:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--do pin-set \
--json '{"id":0, "reference-sync":{"id":1, "state":"connected"}}'

$ ./tools/net/ynl/pyynl/cli.py \

The Rx rings are filled with Rx buffers. Which are supposed to fit
packet headers (or MTU if HW-GRO is disabled). The aggregation buffers
are filled with "device pages". Adjust the sizes of the page pool
recycling ring appropriately, based on ratio of the size of the
buffer on given ring vs system page size. Otherwise on a system
with 64kB pages we end up with >700MB of memory sitting in every
single page pool cache.
Correct the size calculation for the head_pool. Since the buffers
there are always small I'm pretty sure I meant to cap the size
at 1k, rather than make it the lowest possible size. With 64k pages
1k cache with a 1k ring is 64x larger than we need.

net: dsa: ks8995: Fix up bindings
After looking at the datasheets for KS8995 I realized this is
a DSA switch and need to have DT bindings as such and be implemented
as such.
This series just fixes up the bindings and the offending device tree.
The existing kernel driver which is in drivers/net/phy/spi_ks8995.c
does not implement DSA. It can be forgiven for this because it was
merged in 2011 and the DSA framework was not widely established
back then. It continues to probe fine but needs to be rewritten
to use the special DSA tag and moved to drivers/net/dsa as time
permits. (I hope I can do this.)
It's fine for the networking tree to merge both patches, I maintain
ixp4xx as well. But I can also carry the second patch through the
SoC tree if so desired.

Fix up the KS8995 switch and PHYs the way that is most likely:
- Phy 1-4 is certainly the PHYs of the KS8995 (mask 0x1e in
the outoftree code masks PHYs 1,2,3,4).
- Phy 5 is the MII-P5 separate WAN phy of the KS8995 directly
connected to EthC.
- The EthB MII is probably connected as CPU interface to the
KS8995.
Properly integrate the KS8995 switch using the new bindings.

After studying the datasheets for some of the KS8995 variants
it becomes pretty obvious that this is a straight-forward
and simple MII DSA switch with one port in (CPU) and four outgoing
ports, and it even supports custom tags by setting a bit in
a special register, and elaborate VLAN handling as all DSA
switches do.
What is a bit odd with KS8995 is that it uses an extra MII-P5
port to access one of the PHYs separately, on the side of the
switch fabric, such as when using a WAN port separately from
a LAN switch in a home router.
Rewrite the terse bindings to YAML, and move to the proper
subdirectory. Include a verbose example to make things clear.

Currently, for controllers with extended advertising, the advertising
data is set in the asynchronous response handler for extended
adverstising params. As most advertising settings are performed in a
synchronous context, the (asynchronous) setting of the advertising data
is done too late (after enabling the advertising).
Move setting of adverstising data from asynchronous response handler
into synchronous context to fix ordering of HCI commands.

The unconditional call of hci_disable_advertising_sync() in
mesh_send_done_sync() also disables other LE advertisings (non mesh
related).
I am not sure whether this call is required at all, but checking the
adv_instances list (like done at other places) seems to solve the
problem.

According to the message of commit b338d91703fa ("Bluetooth: Implement
support for Mesh"), MGMT_OP_SET_MESH_RECEIVER should set the passive scan
parameters. Currently the scan interval and window parameters are
silently ignored, although user space (bluetooth-meshd) expects that
they can be used [1]

It always seems to be generic/753 that triggers this, and repeating
a quick group test run triggers it every 10-15 iterations. Hence it
generally triggers once up every 30-40 minutes of test time. just
running generic/753 by itself or concurrently with a limited group
of tests doesn't reproduce this issue at all.
Tracing on a hung system shows the AIL repeating every 50ms a log
force followed by an attempt to push pinned, aborted inodes from the
AIL (trimmed for brevity):

....
The inode log items are marked as aborted, which means that either:
a) a transaction commit has occurred, seen an error or shutdown, and
called xfs_trans_free_items() to abort the items. This should happen
before any pinning of log items occurs.
or
b) a dirty transaction has been cancelled. This should also happen
before any pinning of log items occurs.
or
c) AIL insertion at journal IO completion is marked as aborted. In
this case, the log item is pinned by the CIL until journal IO
completes and hence needs to be unpinned. This is then done after
the ->iop_committed() callback is run, so the pin count should be
balanced correctly.
Yet none of these seemed to be occurring. Further tracing indicated
this:
d) Shutdown during CIL pushing resulting in log item completion
being called from checkpoint abort processing. Items are unpinned
and released without serialisation against each other, journal IO
completion or transaction commit completion.
In this case, we may still have a transaction commit in flight that
holds a reference to a xfs_buf_log_item (BLI) after CIL insertion.
e.g. a synchronous transaction will flush the CIL before the
transaction is torn down. The concurrent CIL push then aborts
insertion it and drops the commit/AIL reference to the BLI. This can
leave the transaction commit context with the last reference to the
BLI which is dropped here:
xfs_trans_free_items()
->iop_release
xfs_buf_item_release
xfs_buf_item_put
if (XFS_LI_ABORTED)
xfs_trans_ail_delete
xfs_buf_item_relse()
Unlike the journal completion ->iop_unpin path, this path does not
run stale buffer completion process when it drops the last
reference, hence leaving the stale inodes attached to the buffer
sitting the AIL. There are no other references to those inodes, so
there is no other mechanism to remove them from the AIL. Hence
unmount hangs.
The buffer lock context for stale buffers is passed to the last BLI
reference. This is normally the last BLI unpin on journal IO
completion. The unpin then processes the stale buffer completion and
releases the buffer lock. However, if the final unpin from journal
IO completion (or CIL push abort) does not hold the last reference
to the BLI, there -must- still be a transaction context that
references the BLI, and so that context must perform the stale
buffer completion processing before the buffer is unlocked and the
BLI torn down.
The fix for this is to rework the xfs_buf_item_relse() path to run
stale buffer completion processing if it drops the last reference to
the BLI. We still hold the buffer locked, so the buffer owner and
lock context is the same as if we passed the BLI and buffer to the
->iop_unpin() context to finish stale process on journal commit.
However, we have to be careful here. In a shutdown state, we can be
freeing dirty BLIs from xfs_buf_item_put() via xfs_trans_brelse()
and xfs_trans_bdetach(). The existing code handles this case by
considering shutdown state as "aborted", but in doing so
largely masks the failure to clean up stale BLI state from the
xfs_buf_item_relse() path. i.e regardless of the shutdown state and
whether the item is in the AIL, we must finish the stale buffer
cleanup if we are are dropping the last BLI reference from the
->iop_relse path in transaction commit context.

The stale buffer item completion handling is currently only done
from BLI unpinning. We need to perform this function from where-ever
the last reference to the BLI is dropped, so first we need to
factor this code out into a helper.

The code to initialise, release and free items is all the way down
the bottom of the file. Upcoming fixes need to these functions
earlier in the file, so move them to the top.
There is one code change in this move - the parameter to
xfs_buf_item_relse() is changed from the xfs_buf to the
xfs_buf_log_item - the thing that the function is releasing.
