944de4847a net: hns3: fix RSS config lost after VF reset.
Currently, VF's RSS configuration would be set to default
after VF reset, the the user's one will loss.

To fix it, this patch separates hclgevf_rss_init_hw() into
two parts, one sets up the default RSS configuration and
just be called when driver loading, one configures the hardware
and be called by driver loading or reset.

74ef402e13 net: hns3: fix for fraglist SKB headlen not handling correctly
When the fraglist SKB headlen is larger than zero, current code
still handle the fraglist SKB linear data as frag data, which may
cause TX error.

This patch adds a new DESC_TYPE_FRAGLIST_SKB type to handle the
mapping and unmapping of the fraglist SKB linear data buffer.

According to [1] and [2]:

There seems to be no specific guidance about how to handling the
forward progress guarantee of network device's WQ yet, and other
network device's WQ seem to be marked with WQ_MEM_RECLAIM without
a clear reason.

So this patch removes the WQ_MEM_RECLAIM flag when allocating WQ
to aviod the above warning.

ee91a83e08 net: dsa: Simplify 'dsa_tag_protocol_to_str()'
There is no point in preparing the module name in a buffer. The format
string can be passed diectly to 'request_module()'.

This axes a few lines of code and cleans a few things:
   - max len for a driver name is MODULE_NAME_LEN wich is ~ 60 chars,
     not 128. It would be down-sized in 'request_module()'
   - we should pass the total size of the buffer to 'snprintf()', not the
     size minus 1

cf673ed0e0 net: fix fraglist segmentation reference count leak
Xin Long says:
 On udp rx path udp_rcv_segment() may do segment where the frag skbs
 will get the header copied from the head skb in skb_segment_list()
 by calling __copy_skb_header(), which could overwrite the frag skbs'
 extensions by __skb_ext_copy() and cause a leak.

 This issue was found after loading esp_offload where a sec path ext
 is set in the skb.

Fix this by discarding head state of the fraglist skb before replacing
its contents.

ad59ddd02d Crypto: chelsio - Fixes a hang issue during driver registration
This issue occurs only when multiadapters are present. Hang
happens because assign_chcr_device returns u_ctx pointer of
adapter which is not yet initialized as for this adapter cxgb_up
is not been called yet.

The last_dev pointer is used to determine u_ctx pointer and it
is initialized two times in chcr_uld_add in chcr_dev_add respectively.

The fix here is don't initialize the last_dev pointer during
chcr_uld_add. Only assign to value to it when the adapter's
initialization is completed i.e in chcr_dev_add.

the patch has been applied upstream. To avoid trailing whitespaces in

d7d50f801d drm/i915/perf: Schedule oa_config after modifying the contexts
We wish that the scheduler emit the context modification commands prior
to enabling the oa_config, for which we must explicitly inform it of the
ordering constraints. This is especially important as we now wait for
the final oa_config setup to be completed and as this wait may be on a
distinct context to the state modifications, we need that command packet
to be always last in the queue.

We borrow the i915_active for its ability to track multiple timelines
and the last dma_fence on each; a flexible dma_resv. Keeping track of
each dma_fence is important for us so that we can efficiently schedule
the requests and reprioritise as required.

793012c6c5 ASoC: Intel: bdw-rt5650: Remove ignore_suspend flag from SSP0 dai link
As of commit:
ASoC: soc-core: care .ignore_suspend for Component suspend

function soc-core::snd_soc_suspend no longer ignores 'ignore_suspend'
flag for dai links. While BE dai link for System Pin is
supposed to follow standard suspend-resume flow, appended
'ignore_suspend' flag disturbs that flow and causes audio to break
right after resume. Remove the flag to address this.

c2693514a0 pwm: jz4740: Obtain regmap from parent node
The TCU registers are shared between a handful of drivers, accessing
them through the same regmap.

While this driver is devicetree-compatible, it is never (as of now)
probed from devicetree, so this change does not introduce a ABI problem
with current devicetree files.

485b56f08f pwm: jz4740: Improve algorithm of clock calculation
The previous algorithm hardcoded details about how the TCU clocks work.
The new algorithm will use clk_round_rate to find the perfect clock rate
for the PWM channel.

This code relies on the fact that clk_round_rate() will always round
down, which is not a valid assumption given by the clk API, but only
happens to be true with the clk drivers used for Ingenic SoCs.

Right now, there is no alternative as the clk API does not have a
round-down function (and won't have one for a while), but if it ever
comes to light, a round-down function should be used instead.

ce1f9cece0 pwm: jz4740: Use clocks from TCU driver
The ingenic-timer "TCU" driver provides us with clocks, that can be
(un)gated, reparented or reclocked from devicetree, instead of having
these settings hardcoded in this driver.

The new code now uses a clk pointer per PWM (instead of a clk per
pwm-chip before). So the pointer is stored in per-pwm data now.
The calls to arch-specific timer code is replaced with standard
clock API calls to start and stop each channel's clock.

While this driver is devicetree-compatible, it is never (as of now)
probed from devicetree, so this change does not introduce a ABI problem
with current devicetree files.

Only the Timer control register(TCLR) cannot be updated when the timer
is running. Registers like Counter register (TCRR), loader register
(TLDR) and match register (TMAR) can be updated while the counter is
running. Since TCLR is not updated in pwm_omap_dmtimer_config(), do not
stop the timer for period/duty_cycle update.

867beb60d1 pwm: omap-dmtimer: Fix PWM enabling sequence
To configure DM timer in PWM mode the following needs to be set in
OMAP_TIMER_CTRL_REG using set_pwm callback:
- Set toggle mode on PORTIMERPWM output pin
- Set trigger on overflow and match on PORTIMERPWM output pin.
- Set auto reload

This is a one time configuration and needs to be set before the start of
the DM timer. But the current driver tries to set the same configuration
for every period/duty cycle update, which is not needed. So move the PWM
setup before enabling timer and do not update it in
pwm_omap_dmtimer_config().
