Since commit:
0e030a373df3 ("can: flexcan: fix endianess detection")
the fsl,imx53-flexcan isn't compatible with the fsl,p1010-flexcan any more. As
the former accesses the IP core in Little Endian mode and the latter uses Big
Endian mode.
With the conversion of the flexcan DT bindings to yaml, the dt_binding_check
this throws the following error:
Documentation/devicetree/bindings/clock/imx5-clock.example.dt.yaml: can@53fc8000: compatible: 'oneOf' conditional failed, one must be fixed:
['fsl,imx53-flexcan', 'fsl,p1010-flexcan'] is too long
Additional items are not allowed ('fsl,p1010-flexcan' was unexpected)
'fsl,imx53-flexcan' is not one of ['fsl,imx7d-flexcan', 'fsl,imx6ul-flexcan', 'fsl,imx6sx-flexcan']
'fsl,imx53-flexcan' is not one of ['fsl,ls1028ar1-flexcan']
'fsl,imx6q-flexcan' was expected
'fsl,lx2160ar1-flexcan' was expected
From schema: /builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml
The error is fixed by replacing the "fsl,p1010-flexcan" compatible
(which turned out the be incompatible) with "fsl,imx25-flexcan" in the
binding example.

[robh: Add "fsl,imx25-flexcan" as fallback]
Signed-off-by: Rob Herring <robh@kernel.org>
As both the i.MX35 and i.MX53 flexcan IP cores are compatible to the i.MX25,
they are listed as:
compatible = "fsl,imx35-flexcan", "fsl,imx25-flexcan";
and:
compatible = "fsl,imx53-flexcan", "fsl,imx25-flexcan";
in the SoC device trees.
This patch fixes the following errors, which shows up during a dtbs_check:
arch/arm/boot/dts/imx53-ard.dt.yaml: can@53fc8000: compatible: 'oneOf' conditional failed, one must be fixed:

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. We should decrease the usage count
whetever it succeeded or failed(maybe runtime of the device has
error, or device is in inaccessible state, or other error state).
If we do not call put operation to decrease the reference, it will
result in reference leak in xhci_histb_probe. Moreover, this
device cannot enter the idle state and always stay busy or other
non-idle state later. So we fixed it by jumping to error handling
branch.

The commit eaf2d2f6895d ("ARM: dts: exynos: add input clock to CMU in
Exynos4412 Odroid") breaks probing of usb3503 USB hub on Odroid U3.
It changes the order of clock drivers probe: the clkout (Exynos PMU)
driver is probed before the main clk-exynos4 driver. The clkout driver
on Exynos4412 depends on clk-exynos4 but it does not support deferred
probe, therefore this dependency and changed probe order causes probe
failure.
The usb3503 USB hub on Odroid U3 on the other hand requires clkout
clock. This can be seen in logs:

For AMD SEV guests, update the cr3_lm_rsvd_bits to mask

SEV guests fail to boot on a system that supports the PCID feature.
While emulating the RSM instruction, KVM reads the guest CR3
and calls kvm_set_cr3(). If the vCPU is in the long mode,
kvm_set_cr3() does a sanity check for the CR3 value. In this case,
it validates whether the value has any reserved bits set. The
reserved bit range is 63:cpuid_maxphysaddr(). When AMD memory
encryption is enabled, the memory encryption bit is set in the CR3
value. The memory encryption bit may fall within the KVM reserved
bit range, causing the KVM emulation failure.
Introduce a new field cr3_lm_rsvd_bits in kvm_vcpu_arch which will
cache the reserved bits in the CR3 value. This will be initialized
to rsvd_bits(cpuid_maxphyaddr(vcpu), 63).
If the architecture has any special bits(like AMD SEV encryption bit)
that needs to be masked from the reserved bits, should be cleared
in vendor specific kvm_x86_ops.vcpu_after_set_cpuid handler.

The recent changes to store the MSI irqdomain pointer in struct device
missed that Intel DMAR does not register virtual function devices. Due to
that a VF device gets the plain PCI-MSI domain assigned and then issues
compat MSI messages which get caught by the interrupt remapping unit.
Cure that by inheriting the irq domain from the physical function
device.
Ideally the irqdomain would be associated to the bus, but DMAR can have
multiple units and therefore irqdomains on a single bus. The VF 'bus' could
of course inherit the domain from the PF, but that'd be yet another x86
oddity.

When processing request to add/replace user-defined element set, check
of given element identifier and decision of numeric identifier is done
in "__snd_ctl_add_replace()" helper function. When the result of check
is wrong, the helper function returns error code. The error code shall
be returned to userspace application.
Current implementation includes bug to return zero to userspace application
regardless of the result. This commit fixes the bug.

During memory hotplug process, the linear mapping should not be created for
a given memory range if that would fall outside the maximum allowed linear
range. Else it might cause memory corruption in the kernel virtual space.
Maximum linear mapping region is [PAGE_OFFSET..(PAGE_END -1)] accommodating
both its ends but excluding PAGE_END. Max physical range that can be mapped
inside this linear mapping range, must also be derived from its end points.
This ensures that arch_add_memory() validates memory hot add range for its
potential linear mapping requirements, before creating it with
__create_pgd_mapping().

There is a NULL pointer crash when DCN disabled on headless SKU.
On normal SKU, the variable adev->ddev.mode_config.funcs is
initialized in dm_hw_init(), and it is fine to access it in
amdgpu_device_resume(). But on headless SKU, DCN is disabled,
the funcs variable is not initialized, then crash arises.

The x25_disconnect function in x25_subr.c would decrease the refcount of
"x25->neighbour" (struct x25_neigh) and reset this pointer to NULL.
However, the x25_rx_call_request function in af_x25.c, which is called
when we receive a connection request, does not increase the refcount when
it assigns the pointer.
Fix this issue by increasing the refcount of "struct x25_neigh" in
x25_rx_call_request.
This patch fixes frequent kernel crashes when using AF_X25 sockets.

Jakub pointed out that ncsi_register_dev is obviously broken, because
there is only one family so it would never work if there was more than
one ncsi netdev.
Fix the crash by registering the netlink family once on boot, and drop
