As an optimisation, only pages mapped with PROT_MTE in user space have
the MTE tags zeroed. This is done lazily at the set_pte_at() time via
mte_sync_tags(). However, this function is missing a barrier and another
CPU may see the PTE updated before the zeroed tags are visible. Add an
smp_wmb() barrier if the mapping is Normal Tagged.

In arm64_relocate_new_kernel() we load some fields out of the kimage
structure after relocation has occurred. As the kimage structure isn't
allocated to be relocation-safe, it may be clobbered during relocation,
and we may load junk values out of the structure.
Due to this, kexec may fail when the kimage allocation happens to fall
within a PA range that an object will be relocated to. This has been
observed to occur for regular kexec on a QEMU TCG 'virt' machine with
2GiB of RAM, where the PA range of the new kernel image overlaps the
kimage structure.
Avoid this by ensuring we load all values from the kimage structure
prior to relocation.
I've tested this atop v5.16 and v5.18-rc6.

During hotplug, the stolen time data structure is unmapped and memset.
There is a possibility of the timer IRQ being triggered before memset
and stolen time is getting updated as part of this timer IRQ handler. This
causes the below crash in timer handler -

In vmxnet3_rq_create(), when dma_alloc_coherent() fails,
vmxnet3_rq_destroy() is called. It sets rq->rx_ring[i].base to NULL. Then
vmxnet3_rq_create() returns an error to its callers mxnet3_rq_create_all()
-> vmxnet3_change_mtu(). Then vmxnet3_change_mtu() calls
vmxnet3_force_close() -> dev_close() in error handling code. And the driver
calls vmxnet3_close() -> vmxnet3_quiesce_dev() -> vmxnet3_rq_cleanup_all()
-> vmxnet3_rq_cleanup(). In vmxnet3_rq_cleanup(),
rq->rx_ring[ring_idx].base is accessed, but this variable is NULL, causing
a NULL pointer dereference.
To fix this possible bug, an if statement is added to check whether
rq->rx_ring[0].base is NULL in vmxnet3_rq_cleanup() and exit early if so.
The error log in our fault-injection testing is shown as follows:

In vmxnet3_rq_alloc_rx_buf(), when dma_map_single() fails, rbi->skb is
freed immediately. Similarly, in another branch, when dma_map_page() fails,
rbi->page is also freed. In the two cases, vmxnet3_rq_alloc_rx_buf()
returns an error to its callers vmxnet3_rq_init() -> vmxnet3_rq_init_all()
-> vmxnet3_activate_dev(). Then vmxnet3_activate_dev() calls
vmxnet3_rq_cleanup_all() in error handling code, and rbi->skb or rbi->page
are freed again in vmxnet3_rq_cleanup_all(), causing use-after-free bugs.
To fix these possible bugs, rbi->skb and rbi->page should be cleared after
they are freed.

The global blackhole_netdev has replaced pernet loopback_dev to become the
one given to the object that holds an netdev when ifdown in many places of
ipv4 and ipv6 since commit 8d7017fd621d ("blackhole_netdev: use
blackhole_netdev to invalidate dst entries").
Especially after commit faab39f63c1f ("net: allow out-of-order netdev
unregistration"), it's no longer safe to use loopback_dev that may be
freed before other netdev.
This patch is to set dst dev to blackhole_netdev instead of loopback_dev
in ifdown.
v1->v2:
- add Fixes tag as Eric suggested.

The following two scenarios were failing for lan966x.
1. If the port had the address X and then trying to assign the same
address, then the HW was just removing this address because first it
tries to learn new address and then delete the old one. As they are
the same the HW remove it.
2. If the port eth0 was assigned the same address as one of the other
ports eth1 then when assigning back the address to eth0 then the HW
was deleting the address of eth1.
The case 1. is fixed by checking if the port has already the same
address while case 2. is fixed by checking if the address is used by any
other port.

The 'shift' field is not validated, and any value above 31 will
trigger out-of-bounds. The issue predates the git history, but
syzbot was able to trigger it only after the commit mentioned in
the fixes tag, and this change only applies on top of such commit.
Address the issue bounding the 'shift' value to the maximum allowed

At cleaning up and moving the device rename from the quirk table to
its own table, we removed the entry for Rane SL-1 as we thought it's
only for renaming. It turned out, however, that the quirk is required
for matching with the device that declares itself as no standard
audio but only as vendor-specific.
Restore the quirk entry for Rane SL-1 to fix the regression.

In IPv4 setting the "disable_policy" flag on a device means no policy
should be enforced for traffic originating from the device. This was
implemented by seting the DST_NOPOLICY flag in the dst based on the
originating device.
However, dsts are cached in nexthops regardless of the originating
devices, in which case, the DST_NOPOLICY flag value may be incorrect.
Consider the following setup:
+------------------------------+
| ROUTER |
+-------------+ | +-----------------+ |
| ipsec src |----|-|ipsec0 | |
+-------------+ | |disable_policy=0 | +----+ |
| +-----------------+ |eth1|-|-----
+-------------+ | +-----------------+ +----+ |
| noipsec src |----|-|eth0 | |
+-------------+ | |disable_policy=1 | |
| +-----------------+ |
+------------------------------+
Where ROUTER has a default route towards eth1.
dst entries for traffic arriving from eth0 would have DST_NOPOLICY
and would be cached and therefore can be reused by traffic originating
from ipsec0, skipping policy check.
Fix by setting a IPSKB_NOPOLICY flag in IPCB and observing it instead
of the DST in IN/FWD IPv4 policy checks.

There are 2 ways an engine can get reset in i915 and the method of reset
affects how KMD labels a context as guilty/innocent.
(1) GuC initiated engine-reset: GuC resets a hung engine and notifies
KMD. The context that hung on the engine is marked guilty and all other
contexts are innocent. The innocent contexts are resubmitted.
(2) GT based reset: When an engine heartbeat fails to tick, KMD
initiates a gt/chip reset. All active contexts are marked as guilty and
discarded.
In order to correctly mark the contexts as guilty/innocent, pass a mask
of engines that were reset to __guc_reset_context.

Indeed, the Protected KVM mode promotes __create_hyp_private_mapping()
to a hypercall as EL1 no longer has access to the hypervisor's stage-1
page-table. However, the call from kvm_init_vector_slots() happens after
pKVM has been initialized on the primary CPU, but before it has been
initialized on secondaries. As such, if the KVM initcall procedure is
migrated from one CPU to another in this window, the hypercall may end up
running on a CPU for which EL2 has not been initialized.
Fortunately, the pKVM hypervisor doesn't rely on the host to re-map the
vectors in the private range, so the hypercall in question is in fact
superfluous. Skip it when pKVM is enabled.

When adding support for the slightly wonky Apple M1, we had to
populate ID_AA64PFR0_EL1.GIC==1 to present something to the guest,
as the HW itself doesn't advertise the feature.
However, we gated this on the in-kernel irqchip being created.
This causes some trouble for QEMU, which snapshots the state of
the registers before creating a virtual GIC, and then tries to
restore these registers once the GIC has been created. Obviously,
between the two stages, ID_AA64PFR0_EL1.GIC has changed value,
and the write fails.
The fix is to actually emulate the HW, and always populate the
field if the HW is capable of it.

Above commit does everything correctly according to the datasheet.
However datasheet wasn't correct.
I got confirmation from hardware engineers that the actual CAN
hardware on Intel Elkhart Lake is based on M_CAN version v3.2.0.
Datasheet was mirroring values from an another specification which was
based on earlier M_CAN version leading to wrong bit timings.
Therefore revert the commit and switch back to common bit timings.

In gem_rx_refill rx_prepared_head is incremented at the beginning of
the while loop preparing the skb and data buffers. If the skb or data
buffer allocation fails, this BD will be unusable BDs until the head
loops back to the same BD (and obviously buffer allocation succeeds).
In the unlikely event that there's a string of allocation failures,
there will be an equal number of unusable BDs and an inconsistent RX
BD chain. Hence increment the head at the end of the while loop to be
clean.

(patch 1), where closing subflows would sometimes not adjust the PM's
count of active subflows. Patch 2 updates the selftests to exercise the
new code.

Add and delete a bunch of endpoints and verify the
respect of configured limits.
This covers the codepath introduced by the previous patch.

If the PM closes a fully established MPJ subflow or the subflow
creation errors out in it's early stage the subflows counter is
not bumped accordingly.
This change adds the missing accounting, additionally taking care
of updating accordingly the 'accept_subflow' flag.

Pull more drm fixes from Dave Airlie:
"Turns out I was right, some fixes hadn't made it to me yet. The vmwgfx
ones also popped up later, but all seem like bad enough things to fix.
The dma-buf, vc4 and nouveau ones are all pretty small.
The fbdev fixes are a bit more complicated: a fix to cleanup fbdev
devices properly, uncovered some use-after-free bugs in existing
drivers. Then the fix for those bugs wasn't correct. This reverts that
fix, and puts the proper fixes in place in the drivers to avoid the
use-after-frees.
This has had a fair number of eyes on it at this stage, and I'm
confident enough that it puts things in the right place, and is less
dangerous than reverting our way out of the initial change at this
stage.
fbdev:
- revert NULL deref fix that turned into a use-after-free
- prevent use-after-free in fbdev
- efifb/simplefb/vesafb: fix cleanup paths to avoid use-after-frees
dma-buf:
- fix panic in stats setup
vc4:
- fix hdmi build
nouveau:
- tegra iommu present fix
- fix leak in backlight name
vmwgfx:
- Black screen due to fences using FIFO checks on SVGA3
- Random black screens on boot due to uninitialized drm_mode_fb_cmd2
- Hangs on SVGA3 due to command buffers being used with gbobjects"

The manual describes function 0x6 of pin PA2 as "SPI1_CLK", so change
the comment to reflect that.

Change suniv f1c100s pinctrl,PD14 multiplexing function lvds1 to uart2
When the pin PD13 and PD14 is setting up to uart2 function in dts,
there's an error occurred:
1c20800.pinctrl: unsupported function uart2 on pin PD14
Because 'uart2' is not any one multiplexing option of PD14,
and pinctrl don't know how to configure it.
So change the pin PD14 lvds1 function to uart2.

Before commit 322cff70d46c the fifo_time member of requests on a dispatch
list was not used. Commit 322cff70d46c introduces code that reads the
fifo_time member of requests on dispatch lists. Hence this patch that sets
the fifo_time member when adding a request to a dispatch list.
