Two threads can try to fire the irq_sim with different offsets and will
end up fighting for the irq_work asignment. Thomas Gleixner suggested a
solution based on a bitfield where we set a bit for every offset
associated with an interrupt that should be fired and then iterate over
all set bits in the interrupt handler.
This is a slightly modified solution using a bitmap so that we don't
impose a limit on the number of interrupts one can allocate with
irq_sim.

Since the addition of platform MSI support, there were two helpers
supposed to allocate/free IRQs for a device:
platform_msi_domain_alloc_irqs()
platform_msi_domain_free_irqs()
In these helpers, IRQ descriptors are allocated in the "alloc" routine
while they are freed in the "free" one.
Later, two other helpers have been added to handle IRQ domains on top
of MSI domains:
platform_msi_domain_alloc()
platform_msi_domain_free()
Seen from the outside, the logic is pretty close with the former
helpers and people used it with the same logic as before: a
platform_msi_domain_alloc() call should be balanced with a
platform_msi_domain_free() call. While this is probably what was
intended to do, the platform_msi_domain_free() does not remove/free
the IRQ descriptor(s) created/inserted in
platform_msi_domain_alloc().
One effect of such situation is that removing a module that requested
an IRQ will let one orphaned IRQ descriptor (with an allocated MSI
entry) in the device descriptors list. Next time the module will be
inserted back, one will observe that the allocation will happen twice
in the MSI domain, one time for the remaining descriptor, one time for
the new one. It also has the side effect to quickly overshoot the
maximum number of allocated MSI and then prevent any module requesting
an interrupt in the same domain to be inserted anymore.
This situation has been met with loops of insertion/removal of the
mvpp2.ko module (requesting 15 MSIs each time).

Currently, we are deleting offloaded encap flows in case the relevant neigh
becomes unconnected while the encap is valid (a sign that it used to be
connected), or if the curr neigh mac is different from the cached mac
(a sign that the remote side changed their mac).
The 2nd check also applies when the neigh becomes connected on the 1st
time (we start with zero mac). Before the offending commit, the deleting
handler was practically no op, as no flows were offloaded. But since
that commit, we offload neigh-less encap flows to slow path.
Under mirroring scheme, we go into the delete handler, attempt to unoffload a
mirror rule which was never set (as we were offloading to slow path) and crash.
Fix that by calling the delete handler only when the encap is valid,
which covers both cases mentioned above.

This driver adds support for missing hotkeys on some Huawei laptops.
Laptops such as the Matebook X have non functioning hotkeys. Whereas
newer laptops such as the Matebook X Pro come with working hotkeys out
of the box.
Old laptops, such as the Matebook X, report hotkey events through ACPI
device "\WMI0". However, new laptops, such as the Matebook X Pro, does
not have this WMI device.
All the hotkeys on the Matebook X Pro work fine without this patch
except (micmute, wlan, and huawei key). These keys and the brightness
keys report events to "\AMW0" ACPI device. One problem is that
brightness keys on the Matebook X Pro work without this patch. This
results in reporting two brightness key press events one is captured
by ACPI and another by this driver.
A solution would be to check if such event came from the "\AMW0" WMI
driver then skip reporting event. Another solution would be to leave
this to user-space to handle. Which can be achieved by using "hwdb"
tables and remap those keys to "unknown". This solution seems more
natural to me because it leaves the decision to user-space.

- Patch 1 adds a missing write barrier between used idx updating and

- Patch 2-3 brings back the protection of device IOTLB through vq

Please consider them for -stable.
Changes from V2:
- drop dirty page fix and make it for net-next
Changes from V1:
- silent compiler warning for 32bit.
- use mutex_trylock() on slowpath instead of mutex_lock() even on fast
path.

This reverts commit 78139c94dc8c96a478e67dab3bee84dc6eccb5fd. We don't
protect device IOTLB with vq mutex, which will lead e.g use after free
for device IOTLB entries. And since we've switched to use
mutex_trylock() in previous patch, it's safe to revert it without
having deadlock.

We used to hold the mutex of paired virtqueue in
vhost_net_busy_poll(). But this will results an inconsistent lock
order which may cause deadlock if we try to bring back the protection
of device IOTLB with vq mutex that requires to hold mutex of all
virtqueues at the same time.
Fix this simply by switching to use mutex_trylock(), when fail just
skip the busy polling. This can happen when device IOTLB is under
updating which should be rare.

When boxes are run near (or to) OOM, we have a problem with the discard
page allocation in sd. If we fail allocating the special page, we return
busy, and it'll get retried. But since ordering is honored for dispatch
requests, we can keep retrying this same IO and failing. Behind that IO
could be requests that want to free memory, but they never get the
chance. This means you get repeated spews of traces like this:

Ensure that the discard page allocation has a mempool backing, so we
know we can make progress.

git://people.freedesktop.org/~robclark/linux into drm-next
This time around, seeing some love for some older hw:
- a2xx gpu support for apq8060 (hp touchpad) and imx5 (headless
gpu-only mode)
- a2xx gpummu support (a2xx was pre-iommu)
- mdp4 display support for apq8060/touchpad
For display/dpu:
- a big pile of continuing dpu fixes and cleanups
On the gpu side of things:
- per-submit statistics and traceevents for better profiling
- a6xx crashdump support
- decouple get_iova() and page pinning.. so we can unpin from
physical memory inactive bo's while using softpin to lower
cpu overhead
- new interface to set debug names on GEM BOs and debugfs
output improvements
- additional submit flag to indicate buffers that are used
to dump (so $debugfs/rd cmdstream dumping is useful with
softpin + state-objects)

Mostly just initial support for Turing TU104/TU106 chipsets. Support
for TU102 is missing as I don't yet have HW, but it should be trivial
to add in later in the merge window (in theory).
It's a bit of a rough first pass that'll get improved in future
releases as a finish figuring out some of the other HW changes, but
it's good enough as it stands for modesetting and suspend/resume etc.
Acceleration bring-up is incomplete due to NVIDIA not yet having
provided FW images for me to use, though command submission and copy
engines are functional already.

Driver sends update-SVID ramrod in the MFW notification path.
If there is a pending ramrod, driver doesn't retry the command
and storm firmware will never be updated with the SVID value.
The patch adds changes to send update-svid ramrod in process context with
retry/poll flags set.

There will be only one PHC clock per port. PTP should be enabled only on
one PF per port. The change enables PTP functionality on the PF that
initializes the port. The change is useful in multi-function modes e.g.,
NPAR where a port can have more than one PF.

Vlans are not getting removed when drivers are unloaded. The recent storm
firmware versions had added safeguards against re-configuring an already
configured vlan. As a result, PF inner reload flows (e.g., mtu change)
might trigger an assertion.
This change is going to remove vlans (same as we do for MACs) when doing
a chip cleanup during unload.

On some customer setups it was observed that shmem contains a non-zero fip
MAC for 57711 which would lead to enabling of SW FCoE.
Add a software workaround to clear the bad fip mac address if no FCoE
connections are supported.
