779cb5ba64 drm/i915/dpt: Treat the DPT BO as a framebuffer
Currently i915_gem_object_is_framebuffer() doesn't treat the
BO containing the framebuffer's DPT as a framebuffer itself.
This means eg. that the shrinker can evict the DPT BO while
leaving the actual FB BO bound, when the DPT is allocated
from regular shmem.

That causes an immediate oops during hibernate as we
try to rewrite the PTEs inside the already evicted
DPT obj.

TODO: presumably this might also be the reason for the
DPT related display faults under heavy memory pressure,
but I'm still not sure how that would happen as the object
should be pinned by intel_dpt_pin() while in active use by
the display engine...

5f5ac460df PCI: imx6: Install the fault handler only on compatible match
commit bb38919ec5 ("PCI: imx6: Add support for i.MX6 PCIe controller")
added a fault hook to this driver in the probe function. So it was only
installed if needed.

commit bde4a5a00e ("PCI: imx6: Allow probe deferral by reset GPIO")
moved it from probe to driver init which installs the hook unconditionally
as soon as the driver is compiled into a kernel.

When this driver is compiled as a module, the hook is not registered
until after the driver has been matched with a .compatible and
loaded.

commit 415b6185c5 ("PCI: imx6: Fix config read timeout handling")
extended the fault handling code.

commit 2d8ed461db ("PCI: imx6: Add support for i.MX8MQ")
added some protection for non-ARM architectures, but this does not
protect non-i.MX ARM architectures.

Since fault handlers can be triggered on any architecture for different
reasons, there is no guarantee that they will be triggered only for the
assumed situation, leading to improper error handling (i.MX6-specific
imx6q_pcie_abort_handler) on foreign systems.

I had seen strange L3 imprecise external abort messages several times on
OMAP4 and OMAP5 devices and couldn't make sense of them until I realized
they were related to this unused imx6q driver because I had
CONFIG_PCI_IMX6=y.

Note that CONFIG_PCI_IMX6=y is useful for kernel binaries that are designed
to run on different ARM SoC and be differentiated only by device tree
binaries. So turning off CONFIG_PCI_IMX6 is not a solution.

Therefore we check the compatible in the init function before registering
the fault handler.

25d165c498 wifi: ath12k: incorrect channel survey dump
When underlying hardware supports more than one band, then wiphy
is aware of all the frequency bands present. Example, say
wiphy0 is aware of 2 GHz, 5 GHz and 6 GHz band information.
Hence, when an virtual AP interface is brought up in auto channel
selection on each band. Survey is initiated from the userspace application
for all the virtual AP interfaces simultaneously.

For survey dump collection, freq_to_idx() api is used to map the index of
particular frequency to populate its survey. When the dump was collected,
the index fetched was incorrect. Example, in case of multi-hardware,
the index of channel 36 was reported as 14, because wiphy0 had index 0-13
for 2 GHz channels, instead of 0 for that ar which resulted in invalid
survey sent to userspace application.

The incorrect index was because of the mapping did not consider whether
the freq band is present in its radio structure (ar) or not.

To handle this, the freq_to_idx() api should map index for the
particular band in the ar structure.

When a data traffic with size greater than 1500 is initiated,
say size 65500, it is sent as a set of AMSDUs (3 MSDUs)
in a MPDU.

These AMSDUs are incorrectly classified as multicast
and peer id gets changed, except for first msdu,
because of mcast_bcast bit derived from rx_desc
for every msdu received.

The mcast_bcast bit in rx_desc is only valid for
first msdu. Hence, add changes to derive mcast_bcast
only if it is a first msdu.

4b50d42052 wifi: ath12k: fill peer meta data during reo_reinject
Firmware expects physical address in the reo entrance ring when MLO is
enabled and peer meta data in the queue_addr_lo for the non MLO cases.
Current implementation fills the physical address for the non MLO cases
and firmware decodes it differently which leads to SOC CSR region
access which is not related to firmware/MAC operation.

Fix this by sending only peer_meta data and destination indication bit
during non MLO case. This prevents firmware from invalid decoding.

dcfbb67e48 driver core: class: use lock_class_key already present in struct subsys_private
In commit 37e98d9bed ("driver core: bus: move lock_class_key into
dynamic structure"), we moved the lock_class_key into the internal
structure shared by busses and classes, but only used it for buses.

Move the class code to use this structure as it is already present and
being allocated, instead of the statically allocated on-the-stack
variable that class_create() was using as part of a macro wrapper around
the core function call.

d946716325 RDMA/rxe: Rewrite rxe_task.c
This patch is a major rewrite of the tasklet routines in rxe_task.c.  The
main motivation for this is the realization that the code violates the
safety of the qp pointer by correct reference counting.  When a tasklet is
scheduled from a verbs API the calling thread has a valid reference to the
qp and schedules the tasklet to run at a later time carrying a pointer to
the qp. Once the calling code returns however the qp can be destroyed at
any time. In order to correct this a reference to the qp must be taken
when the task is scheduled and held until it finishes running. This is
complicated by the tasklet library not alwys running a task that is
scheduled depending on whether someone else has scheduled it.

This patch moves the logic for deciding whether to run or schedule a task
outside of do_task() and guarantees that there is only one copy of the
task scheduled or running at a time.

Secondly the separate flags controlling teardown and draining of the task
are included in the task state machine and all references to the state are
protected by spinlocks to avoid consistency and memory barrier issues.

960ebe97e5 RDMA/rxe: Remove __rxe_do_task()
The subroutine __rxe_do_task is not thread safe and it has no way to
guarantee that the tasks, which are designed with the assumption that they
are non-reentrant, are not reentered. All of its uses are non-performance
critical.

This patch replaces calls to __rxe_do_task with calls to
rxe_sched_task. It also removes irrelevant or unneeded if tests.

Instead of calling the task machinery a single call to the tasklet
function (rxe_requester, etc.) is sufficient to draing the queues if task
execution has been disabled or stopped.

Together these changes allow the removal of __rxe_do_task.

a246aa2e8a RDMA/rxe: Remove qp reference counting in tasks
Currently each of the three tasklets requester, completer and responder in
the rxe driver take and release a reference to the qp argument at the
beginning and end of the subroutines. The caller passing in the qp
argument should be responsible for holding a reference to qp so these are
not required. Further doing so breaks the qp cleanup code in
rxe_qp_do_cleanup which calls these routines after all the references have
been dropped so they cannot drain the packet and work request queues as
intended.

In fact if these routines are deferred by calling tasklet_schedule there
is no guarantee that the calling code does have a qp reference.  That is a
bug in rxe_task.c which will be fixed later in this series.

On some platforms there are some platform devices created with
invalid names. For example: "HID-SENSOR-INT-020b?.39.auto" instead
of "HID-SENSOR-INT-020b.39.auto"

This string include some invalid characters, hence it will fail to
properly load the driver which will handle this custom sensor. Also
it is a problem for some user space tools, which parses the device
names from ftrace and dmesg.

This is because the string, real_usage, is not NULL terminated and
printed with %s to form device name.

To address this, initialize the real_usage string with 0s.
