The recent change to validate the RTC turned out to be overly tight.
While it cures the problem on the reporters machine it breaks machines
with Intel chipsets which use bit 0-5 of the D register. So check only
for bit 6 being 0 which is the case on these Intel machines as well.

mlx5 fixes 2021-02-01
Please note the first patch in this series
("Fix function calculation for page trees") is fixing a regression
due to previous fix in net which you didn't include in your previous
rc pr. So I hope this series will make it into your next rc pr,
so mlx5 won't be broken in the next rc.

So far phy_disconnect() is called before free_irq(). If CONFIG_DEBUG_SHIRQ
is set and interrupt is shared, then free_irq() creates an "artificial"
interrupt by calling the interrupt handler. The "link change" flag is set
in the interrupt status register, causing phylib to eventually call
phy_suspend(). Because the net_device is detached from the PHY already,
the PHY driver can't recognize that WoL is configured and powers down the
PHY.

Commit 0a038c1c29a7 ("drm/vc4: Move LBM creation out of
vc4_plane_mode_set()") changed the LBM allocation logic from first
allocating the LBM memory for the plane to running mode_set,
adding a gap in the LBM, and then running the dlist allocation filling
that gap.
The gap was introduced by incrementing the dlist array index, but was
never checking whether or not we were over the array length, leading
eventually to memory corruptions if we ever crossed this limit.
vc4_dlist_write had that logic though, and was reallocating a larger
dlist array when reaching the end of the buffer. Let's share the logic
between both functions.

The DP PHY vswing/pre-emphasis level programming the driver does is
related to the DPTX -> first LTTPR link segment only. Accordingly it
should be only programmed when link training the first LTTPR and kept
as-is when training subsequent LTTPRs and the DPRX. For these latter
PHYs the vs/pe levels will be set in response to writing the
DP_TRAINING_LANEx_SET_PHY_REPEATERy DPCD registers (by an upstream LTTPR
TX PHY snooping this write access of its downstream LTTPR/DPRX RX PHY).
The above is also described in DP Standard v2.0 under 3.6.6.1.
While at it simplify and add the LTTPR that is link trained to the debug
message in intel_dp_set_signal_levels().

Atm the driver will calculate a wrong MST timeslots/MTP (aka time unit)
value for MST streams if the link parameters (link rate or lane count)
are limited in a way independent of the sink capabilities (reported by
DPCD).
One example of such a limitation is when a MUX between the sink and
source connects only a limited number of lanes to the display and
connects the rest of the lanes to other peripherals (USB).
Another issue is that atm MST core calculates the divider based on the
backwards compatible DPCD (at address 0x0000) vs. the extended
capability info (at address 0x2200). This can result in leaving some
part of the MST BW unused (For instance in case of the WD19TB dock).
Fix the above two issues by calculating the PBN divider value based on
the rate and lane count link parameters that the driver uses for all
other computation.

Receiving the first packet in an AMS sequence signals the
beginning of AMS. Set in_ams flag to true when SRC_CAPS are
received during POWER_NEGOTIATION AMS.
This fixes the failure flagged while running TD.PD.SNK.E9
compliance test.
>From Deterministic PD compliance MOI spec:
TD.PD.SNK.E9. GetSinkCap in Place of Accept
Description:
As Provider, the Tester intentionally sends a GetSinkCap message in place
of Accept message and verifies the UUT will send a SoftReset and recover
from the error.
Steps:
a) Run PROC.PD.E1 Bring-up according to the UUT role.
b) The Tester cycles VBus.
c) The Tester sends a Source Capabilities message to the UUT.
d) Upon receipt of a Request message from the UUT, the Tester replies with
a GoodCRC message.
e) The Tester sends a GetSinkCap message to the UUT.
f) If a SoftReset is not received within 15 ms after the GetSinkCap EOP was
sent, the test fails.
g) If a SoftReset is received timely, the Tester replies with an Accept
message.
h) The Tester sends Source Capabilities message to the UUT repeatedly until
nCapsCount reached or a GoodCRC is received. If nCapsCount reached, the
test fails.
i) If a Request is not received timely within 30 ms after the GoodCRC EOP
corresponding to Source Capabilities message was received, the test
fails.

While in source mode, vbus could be shutoff by protections
circuits. TCPM does not move back to toggling state to
re-initiate connection. Fix this by moving to SRC_UNATTACHED
state when vbus shuts off while in source mode.

Simplify the frontbuffer unpin by removing the lock requirement. The LRU
bumping was primarily to protect the GTT from being evicted and from
frontbuffers being eagerly shrunk. Now we protect frontbuffers from the
shrinker, and we avoid accidentally evicting from the GTT, so the
benefit from bumping LRU is no more, and we can save more time by not.

If we enable_breadcrumbs for a request while that request is being
removed from HW; we may see that the request is active as we take the
ce->signal_lock and proceed to attach the request to ce->signals.
However, during unsubmission after marking the request as inactive, we
see that the request has not yet been added to ce->signals and so skip
the removal. Pull the check during cancel_breadcrumbs under the same
spinlock as enabling so that we the two tests are consistent in
enable/cancel.
Otherwise, we may insert a request onto ce->signals that we expect should
not be there:
intel_context_remove_breadcrumbs:488 GEM_BUG_ON(!__i915_request_is_complete(rq))
While updating, we can note that we are always called with
irqs-disabled, due to the engine->active.lock being held at the single
caller, and so remove the irqsave/restore making it symmetric to
enable_breadcrumbs.

v2: Tweak reference counting so that we only acquire a new reference on

Prevent the ICL HDR plane pipeline from performing YUV color range
correction twice when the input is in limited range. This is done by
removing the limited-range code from icl_program_input_csc().
Before this patch the following could happen: user space gives us a YUV
buffer in limited range; per the pipeline in [1], the plane would first
go through a "YUV Range correct" stage that expands the range; the plane
would then go through the "Input CSC" stage which would also expand the
range because icl_program_input_csc() would use a matrix and an offset
that assume limited-range input; this would ultimately cause dark and
light colors to appear darker and lighter than they should respectively.
This is an issue because if a buffer switches between being scanned out
and being composited with the GPU, the user will see a color difference.
If this switching happens quickly and frequently, the user will perceive
this as a flickering.

Some Kingston A2000 NVMe SSDs sooner or later get confused and stop
working when they use the deepest APST sleep while running Linux. The
system then crashes and one has to cold boot it to get the SSD working
again.
Kingston seems to known about this since at least mid-September 2020:
https://bbs.archlinux.org/viewtopic.php?pid=1926994#p1926994
Someone working for a German company representing Kingston to the German
press confirmed to me Kingston engineering is aware of the issue and
investigating; the person stated that to their current knowledge only
the deepest APST sleep state causes trouble. Therefore, make Linux avoid
it for now by applying the NVME_QUIRK_NO_DEEPEST_PS to this SSD.
I have two such SSDs, but it seems the problem doesn't occur with them.
I hence couldn't verify if this patch really fixes the problem, but all
the data in front of me suggests it should.
This patch can easily be reverted or improved upon if a better solution
surfaces.
FWIW, there are many reports about the issue scattered around the web;
most of the users disabled APST completely to make things work, some
just made Linux avoid the deepest sleep state:
