5ef03dbd91 xfs, proc: hide unused xfs procfs helpers
These two functions now trigger a warning when CONFIG_PROC_FS is disabled:

fs/xfs/xfs_stats.c:128:12: error: 'xqmstat_proc_show' defined but not used [-Werror=unused-function]
 static int xqmstat_proc_show(struct seq_file *m, void *v)

 static int xqm_proc_show(struct seq_file *m, void *v)
            ^~~~~~~~~~~~~

Previously, they were referenced from an unused 'static const' structure,
which is silently dropped by gcc.

We can address the warning by adding the same #ifdef around them that
hides the reference.

05909babce net/mlx5e: Avoid reset netdev stats on configuration changes
Move all RQ, SQ and channel counters from the channel objects into the
priv structure.  With this change, counters will not be reset upon
channel configuration changes.

Channel's statistics for SQs which are associated with TCs higher than
zero will be presented in ethtool -S, only for SQs which were opened at
least once since the module was loaded (regardless of their open/close
current status).  This is done in order to decrease the total amount of
statistics presented and calculated for the common out of box use (no
QoS).

mlx5e_channel_stats is a compound of CH,RQ,SQs stats in order to
create locality for the NAPI when handling TX and RX of the same
channel.

Align the new statistics struct per ring to avoid several channels
update to the same cache line at the same time.
Packet rate was tested, no degradation sensed.

e646e17713 media: vsp1: Move video configuration to a cached dlb
We are now able to configure a pipeline directly into a local display
list body. Take advantage of this fact, and create a cacheable body to
store the configuration of the pipeline in the pipeline object.

vsp1_video_pipeline_run() is now the last user of the pipe->dl object.
Convert this function to use the cached pipe->stream_config body and
obtain a local display list reference.

Attach the pipe->stream_config body to the display list when needed
before committing to hardware.

Use a flag 'configured' to know when we should attach our stream_config
to the next outgoing display list to reconfigure the hardware in the
event of our first frame, or the first frame following a suspend/resume
cycle.

Our video DL usage now looks like the below output:

dl->body0 contains our disposable runtime configuration. Max 41.
dl_child->body0 is our partition specific configuration. Max 12.
dl->bodies shows our constant configuration and LUTs.

  These two are LUT/CLU:
     * dl->bodies[x]->num_entries 256 / max 256
     * dl->bodies[x]->num_entries 4914 / max 4914

Which shows that our 'constant' configuration cache is currently
utilised to a maximum of 64 entries.

5d7936b8e2 media: vsp1: Convert display lists to use new body pool
Adapt the dl->body0 object to use an object from the body pool. This
greatly reduces the pressure on the TLB for IPMMU use cases, as all of
the lists use a single allocation for the main body.

The CLU and LUT objects pre-allocate a pool containing three bodies,
allowing a userspace update before the hardware has committed a previous
set of tables.

Bodies are no longer 'freed' in interrupt context, but instead released
back to their respective pools. This allows us to remove the garbage
collector in the DLM.

5de0473982 media: vsp1: Provide a body pool
Each display list allocates a body to store register values in a dma
accessible buffer from a dma_alloc_wc() allocation. Each of these
results in an entry in the IOMMU TLB, and a large number of display list
allocations adds pressure to this resource.

Reduce TLB pressure on the IPMMUs by allocating multiple display list
bodies in a single allocation, and providing these to the display list
through a 'body pool'. A pool can be allocated by the display list
manager or entities which require their own body allocations.

The suspend and resume handlers are only utilised by video pipelines,
yet the functions currently reside in the vsp1_pipe object.

This causes an issue with resume, as the functions incorrectly call

83967993f2 media: vsp1: Release buffers for each video node
Commit 372b2b0399 ("media: v4l: vsp1: Release buffers in
start_streaming error path") introduced a helper to clean up buffers on
error paths, but inadvertently changed the code such that only the
output WPF buffers were cleaned, rather than the video node being
operated on.

Since then vsp1_video_cleanup_pipeline() has grown to perform both video
node cleanup, as well as pipeline cleanup. Split the implementation into
two distinct functions that perform the required work, so that each
video node can release its buffers correctly on streamoff. The pipe
cleanup that was performed in the vsp1_video_stop_streaming() (releasing
the pipe->dl) is moved to the function for clarity.

3c785e4878 media: adv7511: fix clearing of the CEC receive buffer
The CEC receive buffer was not always cleared correctly. The
datasheet was a bit confusing since sometimes it mentioned that the
bit in CEC register 0x4a had to be toggled, and sometimes it suggested
it was a 'Clear-on-write' bit. But it really needs to be toggled.

The patch also enables/disables the CEC irqs after the other irq are
enabled/disabled instead of doing it before. It may not matter, but it
feels more logical to do it in that order, and the implementation that
we (Cisco) have used until now and that is known to be reliable also
did it in that order.

0220eddac6 udf: Simplify calls to udf_disk_stamp_to_time
Subsequent patches in the series convert inode timestamps
to use struct timespec64 instead of struct timespec as
part of solving the y2038 problem.

commit fd3cfad374 ("udf: Convert udf_disk_stamp_to_time() to use mktime64()")
eliminated the NULL return condition from udf_disk_stamp_to_time().
udf_time_to_disk_time() is always called with a valid dest pointer and
the return value is ignored.
Further, caller can as well check the dest pointer being passed in rather
than return argument.
Make both the functions return void.

This will make the inode timestamp conversion simpler.

e5b1db0186 PCI: Remove unused pcie_get_minimum_link()
In some cases pcie_get_minimum_link() returned misleading information
because it found the slowest link and the narrowest link without
considering the total bandwidth of the link.

For example, consider a path with these two links:

  - 16.0 GT/s  x1 link  (16.0 * 10^9 * 128 / 130) *  1 / 8 = 1969 MB/s
  -  2.5 GT/s x16 link  ( 2.5 * 10^9 *   8 /  10) * 16 / 8 = 4000 MB/s

The available bandwidth of the path is limited by the 16 GT/s link to about
1969 MB/s, but pcie_get_minimum_link() returned 2.5 GT/s x1, which
corresponds to only 250 MB/s.

Callers should use pcie_print_link_status() instead, or
pcie_bandwidth_available() if they need more detailed information.

Remove pcie_get_minimum_link() since there are no callers left.

4695ca9d17 ixgbe: Report PCIe link properties with pcie_print_link_status()
Previously the driver used pcie_get_minimum_link() to warn when the NIC
is in a slot that can't supply as much bandwidth as the NIC could use.

pcie_get_minimum_link() can be misleading because it finds the slowest link
and the narrowest link (which may be different links) without considering
the total bandwidth of each link.  For a path with a 16 GT/s x1 link and a
2.5 GT/s x16 link, it returns 2.5 GT/s x1, which corresponds to 250 MB/s of
bandwidth, not the true available bandwidth of about 1969 MB/s for a
16 GT/s x1 link.

Use pcie_print_link_status() to report PCIe link speed and possible
limitations instead of implementing this in the driver itself.  This finds
the slowest link in the path to the device by computing the total bandwidth
of each link and compares that with the capabilities of the device.

The dmesg change is:

  - PCI Express bandwidth of %dGT/s available
  - (Speed:%s, Width: x%d, Encoding Loss:%s)
  + %u.%03u Gb/s available PCIe bandwidth (%s x%d link)

or, if the device is capable of better performance than is available in the
current slot:

  - This is not sufficient for optimal performance of this card.
  - For optimal performance, at least %dGT/s of bandwidth is required.
  - A slot with more lanes and/or higher speed is suggested.
  + %u.%03u Gb/s available PCIe bandwidth, limited by %s x%d link at %s (capable of %u.%03u Gb/s with %s x%d link)

Note that the driver previously used dev_warn() to suggest using a
different slot, but pcie_print_link_status() uses dev_info() because if the
platform has no faster slot available, the user can't do anything about the
warning and may not want to be bothered with it.

5ab99d48da ARM: stm32: Don't select DMA unconditionally on STM32MP157C
The patch that enabled these had no useful changelog that explains
why it is done, and it causes a build warning:

WARNING: unmet direct dependencies detected for STM32_DMA
  Depends on [n]: DMADEVICES [=n] && (ARCH_STM32 [=y] || COMPILE_TEST [=y])
  Selected by [y]:
  - MACH_STM32MP157 [=y] && ARCH_STM32 [=y] && ARCH_MULTI_V7 [=y]

Generally, platforms should not select arbitrary drivers, so let's
just revert that change.

bd6cc4f2d2 Late omap soc changes for v4.18 merge window
This series contains two omap1 ams-delta GPIO clean-up patches to get
 started with removal of hard-coded GPIO numbers from drivers. And then
 the removal of board mach includes from drivers. The second patch mostly
 touches the ams-delta audio driver but is included here because of the
 removal of the latch gpios and is acked by Mark Brown.
 
 And there are two more am437x related PM patches to save and restore
 control module and timer registers for RTC only suspend mode. Looks like
 the patch title for the timer changes is a bit misleading, not all the
 timer code is yet living under drivers/clocksource. But I had already
 pushed out the branch before I noticed this.

d8f8d467f5 arm64: dts: apq8096-db820c: Removed bt-en-1-8v regulator
This patch removes the unused bt-en-1-8v regulator and moves the
bt_en_gios claim to the pm8994_gpios node.

This bt_en_gpio could have been moved to the bluetooth serial node but
instead this node declares an 'enable' gpio addressing the bt_en_gpio.
This is needed by the Qualcomm QCA6174 WLAN/BT combo chip that needs to
have the bt_en_gpio claimed even if only WLAN is used.

da34314f72 arm64: dts: fix regulator property name for wlan pcie endpoint
The property name vddpe-supply is not included in
Documentation/devicetree/bindings/pci/qcom,pcie.txt
nor in the pcie-qcom PCIe Root Complex driver.

This property name was used in an initial patchset for pcie-qcom,
but was renamed in a later revision.

Therefore, the regulator is currently never enabled, leaving us with
unoperational wlan.

Fix this by using the correct regulator property name, so that wlan
comes up correctly.
