niu_add_ethtool_tcam_entry
When building with -Wsometimes-uninitialized, Clang warns:
drivers/net/ethernet/sun/niu.c:7466:5: warning: variable 'class' is used
uninitialized whenever switch default is taken
[-Wsometimes-uninitialized]
The default case can never happen because i can only be 0 to 3
(NIU_L3_PROG_CLS is defined as 4). To make this clear to Clang,
just zero initialize class in the default case (use the macro
CLASS_CODE_UNRECOG to make it clear this shouldn't happen).

On some architectures, the MMU can be disabled, leading to access_ok()
becoming an empty macro that does not evaluate its size argument,
which in turn produces an unused-variable warning:
drivers/vhost/vhost.c:1191:9: error: unused variable 's' [-Werror,-Wunused-variable]
size_t s = vhost_has_feature(vq, VIRTIO_RING_F_EVENT_IDX) ? 2 : 0;
Mark the variable as __maybe_unused to shut up that warning.

No compatible string for it yet, just the version-dependent changes.
They've now tied the hub and the core interrupt lines into a single
interrupt line coming out of the block. It also turns out I made a
mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
itself -- the bridge is going away in favor of an external reset
controller in a larger HW module.
v2: Use consistent checks for whether we're on 4.2, and fix a leak in
an error path.
v3: Use more general means of determining if the current 4.2 changes
are in place, as apparently other platforms may switch back (noted
by Dave). Update the binding doc.
v4: Improve error handling for IRQ init.

proc_exit_connector() uses ->real_parent lockless. This is not
safe that its parent can go away at any moment, so use RCU to

If we receive a packet while deleting a VXLAN device, there's a chance
vxlan_rcv() is called at the same time as vxlan_dellink(). This is fine,
except that vxlan_dellink() should never ever touch stuff that's still in
use, such as the GRO cells list.
Otherwise, vxlan_rcv() crashes while queueing packets via
gro_cells_receive().
Move the gro_cells_destroy() to vxlan_uninit(), which runs after the RCU
grace period is elapsed and nothing needs the gro_cells anymore.
This is now done in the same way as commit 8e816df87997 ("geneve: Use GRO
cells infrastructure.") originally implemented for GENEVE.

It is debatable whether having an error message on suspend for forcibly
cancelling outstanding work is worthwhile. We want to know if it occurs
in the wild (as we will then have to reconsider the approach!), but
equally is not fatal across suspend, as upon resume we automatically
clear the wedged status.
However, CI does trigger this scenario with gem_eio/suspend; as there we
are intentionally wedging the device upon suspend. The dilemma is how
not to trigger a failure report for the dmesg spam, for which the
quickest response is to suppress the warning in the kernel. I'd rather
mark it as accepted in gem_eio, but for now detecting when gem_eio is
playing games and cancelling the warning for that case seems a barely
acceptable hack.

Commit a72d785021cb ("clk: ti: Prepare for remove of OF node name")
changed the code to use kasprintf() for provider->clkdm_name but also
changed the offset used later on by three. We don't need to change the
offset as we already have the extra three characters in the format for
kasprintf with "%pOFnxxx".
This caused the clocks with TI_CLK_CLKCTRL_COMPAT to have NULL
clk->clkdm_name for omap4 and 5. And null clkdm_name can cause module
reset, enable, and idle to fail.
The issue can also be seen also when enabling DEBUG for clkctrl.c
and then we start seeing "clock: could not associate" messages for
omap4 and 5 as the generated name is something like "l4_wkclkdm" instead
of "l4_wkup_clkdm" that's needed.
Let's fix the issue with a partial revert of commit a72d785021cb ("clk:
ti: Prepare for remove of OF node name").
ALso note that in general code should not depend on the dts node names.
And the node names should be generic types like clock-domain in this case.
This could be fixed later by using separate compatible properties for the
clockdomains, or by adding soc_device_match() table with reg offsets
to the driver. But let's fix the regression first.

of_clk_get_by_name() is using -1 for __of_clk_get() index. It will go
to of_parse_clkspec(), and be used for of_parse_phandle_with_args().
Here, if user doesn't specify clock name (= of_clk_get_by_name(np,
NULL)), this index is still -1, and of_parse_phandle_with_args() will
return -EINVAL (This index will be updated if if it had clock name).
clk_get_by_name(np, NULL) should work, then, default index should be 0
instead of -1. This patch fixes it.

it was tested performing regular user workloads like browsing,
editing documents and compiling Linux, so it is time to enable it by
default and enjoy even more power-savings.

If PSR1 is active when pipe CRC is enabled the CRC calculations will
be inhibit by the transition to low power states that PSR1 brings.
So lets force a PSR1 exit and as soon as pipe CRC is enabled it will
block PSR1 activation and avoid CRC timeouts when running IGT tests.
There is a little window between the call to force exit PSR and the
write to pipe CRC registers that needs to happen within the minimum
of 6 idles frames otherwise PSR1 will be active again causing the CRC
timeouts but anyways this will at least reduce the occurrence of CRC
timeouts.
This can possibily fix issues present right now but I did not found
any open, I mostly got this issue from previous CI runs of this
series, bellow some exambles:

When PSR2 is active aka after the number of frames programmed in
PSR2_CTL 'Frames Before SU Entry' hardware stops to generate CRC
interrupts causing IGT tests to fail due timeout.
This same behavior don't happen with PSR1, as soon as pipe CRC is
enabled it blocks PSR1 activation so CRC calculation continues to
happens normaly.
This patch also set mode_changed as true when PSR is available to
force atomic check functions to compute new PSR state, otherwise PSR2
would not be disabled.
v4: Only setting mode_changed if has_psr is set(Dhinakaran)
v3: Reusing intel_crtc_crc_prepare() and crc_enabled, only setting
mode_changed if it can do PSR.
v2: Changed commit description to describe that PSR2 inhibit CRC
calculations.

Other features like PSR2 also needs to be disabled while getting CRC
so lets rename ips_force_disable to crc_enabled, drop all this checks
for pipe A and HSW and BDW and make it generic and
hsw_compute_ips_config() will take care of all the checks removed
from here.

If has_psr is set it means that CRTC has a EDP panel attached so the

In any commit, intel_modeset_pipe_config() will initialilly clear
and then recalculate most of the pipe states but it leave intel
specific color features states in reset state.
If after intel_pipe_config_compare() is detected that a fastset is
possible it will mark update_pipe as true and unsed mode_changed,
causing the color features state to be kept in reset state and then
latter being committed to hardware disabling the color features.
This issue can be reproduced by any code patch that duplicates the
actual(with color features already enabled) state and only mark
mode_changed as true.

Forcing a specific CRTC to the eDP connector was causing the
intel_psr_fastset_force() to mark mode_chaged in the wrong and
disabled CRTC causing no update in the PSR state.
Looks like our internal state track do not clear output_types and
has_psr in the disabled CRTCs, not sure if this is the expected
behavior or not but in the mean time this fix the issue.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
- The big change this time around is the irqchip handling in the
qualcomm pin controllers, closely coupled with the gpiochip. This
rework, in a classic fall-between-the-chairs fashion has been
sidestepped for too long.
The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms
have been rewritten to use hierarchical irqchip. This creates the
base from which I intend to gradually pull support for hierarchical
irqchips into the gpiolib irqchip helpers to cut down on duplicate
code.
We have too many hacks in the kernel because people have been
working around the missing hierarchical irqchip for years, and once
it was there, noone understood it for a while. We are now slowly
adapting to using it.
This is why this pull requests include changes to MFD, SPMI,
IRQchip core and some ARM Device Trees pertaining to the Qualcomm
chip family. Since Qualcomm have so many chips and such large
deployments it is paramount that this platform gets this right, and
now it (hopefully) does.
- Core support for pull-up and pull-down configuration, also from the
device tree. When a simple GPIO chip supports an "off or on" pull-up
or pull-down resistor, we provide a way to set this up using
machine descriptors or device tree.
If more elaborate control of pull up/down (such as resistance shunt
setting) is required, drivers should be phased over to use pin
control. We do not yet provide a userspace ABI for this pull
up-down setting but I suspect the makers are going to ask for it
soon enough. PCA953x is the first user of this new API.
- The GPIO mockup driver has been revamped after some discussion
improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for both testing
and virtual prototyping, e.g. when you do not yet have a GPIO
expander to play with but really want to get something to develop
code around before hardware is available. It's neat. The blackbox
testing usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating flags.
- A new device core helper for devm_platform_ioremap_resource() is
funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum driver.
- Wakeup support for PCA953x.
- A slew of cleanups in the various Intel drivers"

Legacy behaviour was to allow non-page-aligned mmap requests, as does the
linux mmap(2) implementation by virtue of automatically rounding up for
the caller.
To avoid breaking legacy userspace relax the newly introduced fix.

We may race the interrupt signaling with retirement, in which case the
order in which we acquire the reference inside the interrupt is vital to
provide the correct barrier against the request being freed in
retirement, i.e. we need to acquire our reference before marking the
breadcrumb as cancelled (as soon as the breadcrumb is cancelled
retirement may drop its reference to the request without serialisation
with the interrupt handler).

If we drop the engine lock, we may run execlists_dequeue which may free
the priolist. Therefore if we ever drop the execution lock on the
engine, we have to discard our cache and refetch the priolist to ensure
we do not use a stale pointer.

If we allocate while iterating the rbtree of active nodes, we may hit
the shrinker and so retire the i915_active, reaping the rbtree. Modifying
the rbtree as we iterate is not good behaviour, so acquire the
i915_active first to keep the tree intact whenever we allocate.

The downgrade of the fullmodeset into fastset
intel_encoder->update_pipe, in possible scenario, skips the En/Dis-able
DDI. Hence breaks the HDCP state change handling.
We also don't have any hdcp tests in CI, because the shard runs don't
have hdcp capable outputs :-/
So this change fixs it by handling the HDCP state change request at
intel_encoder->update_pipe too along with enable and disable of the DDI.
Fixes: d19f958db23c ("drm/i915: Enable fastset for non-boot modesets.")
v2:
Added commit id that broke the HDCP [Daniel]
