b3d5f311d3 parisc: asm: psw.h: missing header guard
The psw.h header file contains #ifndef directive of the guard,
but the complimentary #define directive is missing. The patch
adds the appropriate #define to fix the header guard.

a7d8814641 i.MX SoC changes for 5.3:
- Switch imx7d to imx-cpufreq-dt for speed-grading, as imx-cpufreq-dt
    driver can handle speed grading bits on imx7d just like on imx8mq.
  - Improve imx6 cpuidle driver to use raw_spinlock_t.  The change makes
    no difference for !RT build, but is required by RT kernel.

b2c200e3f2 pwm: Add consumer device link
Add a device link between the PWM consumer and the PWM provider. This
enforces the PWM user to get suspended before the PWM provider. It
allows proper synchronization of suspend/resume sequences: the PWM user
is responsible for properly stopping PWM, before the provider gets
suspended: see [1]. Add the device link in:
- of_pwm_get()
- pwm_get()
- devm_*pwm_get() variants
as it requires a reference to the device for the PWM consumer.

9d740d6380 ath10k: Add wrapper function to ath10k debug
ath10k_dbg() is called in ath10k_process_rx() with huge set of arguments
which is causing CPU overhead even when debug_mask is not set.
Good improvement was observed in the receive side performance when call
to ath10k_dbg() is avoided in the RX path.

Since currently all debug messages are sent via tracing infrastructure,
we cannot entirely avoid calling ath10k_dbg. Therefore, call to
ath10k_dbg() is made conditional based on tracing config in the driver.

Trasmit performance remains unchanged with this patch; below are some
experimental results with this patch and tracing disabled.

This is done in order to make the *htt_h2t_aggr_cfg_msg* op align better
with the rest of the htt ops (whom all have inline wrappers).

It also adds support for the case when the op is missing (function
pointer is NULL).

As a result of this, the name of the 32 bit implementation in htt_tx.c
was changed and the function was made static.

9cda7807ee veth: Support bulk XDP_TX
XDP_TX is similar to XDP_REDIRECT as it essentially redirects packets to
the device itself. XDP_REDIRECT has bulk transmit mechanism to avoid the
heavy cost of indirect call but it also reduces lock acquisition on the
destination device that needs locks like veth and tun.

XDP_TX does not use indirect calls but drivers which require locks can
benefit from the bulk transmit for XDP_TX as well.

This patch introduces bulk transmit mechanism in veth using bulk queue
on stack, and improves XDP_TX performance by about 9%.

Here are single-core/single-flow XDP_TX test results. CPU consumptions
are taken from "perf report --no-child".

- Before:

  7.26 Mpps

  _raw_spin_lock  7.83%
  veth_xdp_xmit  12.23%

- After:

  7.94 Mpps

  _raw_spin_lock  1.08%
  veth_xdp_xmit   6.10%

v2:
- Use stack for bulk queue instead of a global variable.

6dbc6e6f58 pinctrl: mcp23s08: Fix add_data and irqchip_add_nested call order
Currently probing of the mcp23s08 results in an error message
"detected irqchip that is shared with multiple gpiochips:
please fix the driver"

This is due to the following:

Call to mcp23s08_irqchip_setup() with call hierarchy:
mcp23s08_irqchip_setup()
  gpiochip_irqchip_add_nested()
    gpiochip_irqchip_add_key()
      gpiochip_set_irq_hooks()

Call to devm_gpiochip_add_data() with call hierarchy:
devm_gpiochip_add_data()
  gpiochip_add_data_with_key()
    gpiochip_add_irqchip()
      gpiochip_set_irq_hooks()

The gpiochip_add_irqchip() returns immediately if there isn't a irqchip
but we added a irqchip due to the previous mcp23s08_irqchip_setup()
call. So it calls gpiochip_set_irq_hooks() a second time.

Fix this by moving the call to devm_gpiochip_add_data before
the call to mcp23s08_irqchip_setup

503d90b306 ALSA: hda/realtek: Add quirks for several Clevo notebook barebones
This adds 4 SND_PCI_QUIRK(...) lines for several barebone models of the ODM
Clevo. The model names are written in regex syntax to describe/match all clevo
models that are similar enough and use the same PCI SSID that this fixup works
for them.

Additionally the lines regarding SSID 0x96e1 and 0x97e1 didn't fix audio for the
all our Clevo notebooks using these SSIDs (models Clevo P960* and P970*) since
ALC1220_FIXP_CLEVO_PB51ED_PINS swapped pins that are not necesarry to be
swapped. This patch initiates ALC1220_FIXUP_CLEVO_P950 instead for these model
and fixes the audio.

4f41845b34 iommu/io-pgtable: Replace IO_PGTABLE_QUIRK_NO_DMA with specific flag
IO_PGTABLE_QUIRK_NO_DMA is a bit of a misnomer, since it's really just
an indication of whether or not the page-table walker for the IOMMU is
coherent with the CPU caches. Since cache coherency is more than just a
quirk, replace the flag with its own field in the io_pgtable_cfg
structure.
