There is currently a warning when building the Kryo cpufreq driver into
the kernel image:

WARNING: vmlinux.o(.text+0x8aa424): Section mismatch in reference from
the function qcom_cpufreq_kryo_probe() to the function

The function qcom_cpufreq_kryo_probe() references
the function __init qcom_cpufreq_kryo_get_msm_id().
This is often because qcom_cpufreq_kryo_probe lacks a __init
annotation or the annotation of qcom_cpufreq_kryo_get_msm_id is wrong.

Remove the '__init' annotation from qcom_cpufreq_kryo_get_msm_id
so that there is no more mismatch warning.

Additionally, Nick noticed that the remove function was marked as
'__init' when it should really be marked as '__exit'.

[Why]
EDID emulation didn't work properly for linux, as we stop programming
if nothing is connected physically.

[How]
We get a flag from DRM when we want to do edid emulation. We check if
this flag is true and nothing is connected physically, if so we only
program the front end using VIRTUAL_SIGNAL.

[Why]
There have been a few reports of Vega10 display remaining blank

change on Vega10 - skip set_bandwidth if stream count is 0.
As a result we skipped dispclk reset on suspend, thus on resume
we may skip the clock update assuming it hasn't been changed.
On some systems it causes display blank or 'out of range'.

This reverts commit 0c08754b.

commit 0c08754b
("drm/panel: Add device_link from panel device to DRM device")
creates a circular dependency under these circumstances:

1. The panel depends on dsi-host because it is MIPI-DSI child
   device.
2. dsi-host depends on the drm parent device (connector->dev->dev)
   this should be allowed.
3. drm parent dev (connector->dev->dev) depends on the panel
   after this patch.

This makes the dependency circular and while it appears it
does not affect any in-tree drivers (they do not seem to have
dsi hosts depending on the same parent device) this does not
seem right.

As noted in a response from Andrzej Hajda, the intent is
likely to make the panel dependent on the DRM device
(connector->dev) not its parent. But we have no way of
doing that since the DRM device doesn't contain any
struct device on its own (arguably it should).

Revert this until a proper approach is figured out.

HP 6730b laptop has an ethernet NIC connected to one of the PCIe root
ports.  The root ports themselves are native PCIe hotplug capable.  Now,
during boot after PCI devices are scanned the BIOS triggers ACPI bus check
directly to the NIC:

  ACPI: \_SB_.PCI0.RP06.NIC_: Bus check in hotplug_event()

It is not clear why it is sending bus check but regardless the ACPI hotplug
notify handler calls enable_slot() directly (instead of going through
acpiphp_check_bridge() as there is no bridge), which ends up handling
special case for non-hotplug bridges with native PCIe hotplug.  This
results a crash of some kind but the reporter only sees black screen so it
is hard to figure out the exact spot and what actually happens.  Based on
a few fix proposals it was tracked to crash somewhere inside
pci_assign_unassigned_bridge_resources().

In any case we should not really be in that special branch at all because
the ACPI notify happened to a slot that is not a PCI bridge (it is just a
regular PCI device).

Fix this so that we only go to that special branch if we are calling
enable_slot() for a bridge (e.g., the ACPI notification was for the
bridge).

We attempt to get fences earlier in the hopes that everything will

in getting a fence, getting one a second time will result in a duplicate

Currently add_modify_gid() for IB link layer has followong issue
in cache update path.

When GID update event occurs, core releases reference to the GID

                                   	This is incorrect.

GID entry state and entry pointer is provides the accurate GID enty
state. Such fields must be updated with rwlock to protect against
readers and, such fields must be in sane state before refcount can drop
to zero. Otherwise above race condition can happen leading to
use-after-free situation.

Following backtrace has been observed when cache update for an IB port
is triggered while IPoIB ULP is creating an AH.

Therefore, when updating GID entry, first mark a valid entry as invalid
through state and set the barrier so that no callers can acquired
the GID entry, followed by release reference to it.

  "libnvdimm/dax for 4.19-rc6

  * (2) fixes for the dax error handling updates that were merged for
  v4.19-rc1. My mails to Al have been bouncing recently, so I do not have
  his ack but the uaccess change is of the trivial / obviously correct
  variety. The address_space_operations fixes a regression.

  * A filesystem-dax fix to correct the zero page lookup to be compatible
   with non-x86 (mips and s390) architectures."

  "USB fixes for 4.19-rc6

   Here are some small USB core and driver fixes for reported issues for
   4.19-rc6.

   The most visible is the oops fix for when the USB core is built into the
   kernel that is present in 4.18.  Turns out not many people actually do
   that so it went unnoticed for a while.  The rest is some tiny typec,
   musb, and other core fixes.

   All have been in linux-next with no reported issues."
