Potentially overflowing expression (ts_freq << 16 and intgr << 16)
declared as type u32 (32-bit unsigned) is evaluated using 32-bit
arithmetic and then used in a context that expects an expression of
type u64 (64-bit unsigned) which ultimately is used as 16-bit
unsigned by typecasting to u16. Fixed by using an unsigned 32-bit
integer since the value is truncated anyway in the end.

This makes the driver use the irqchip template to assign
properties to the gpio_irq_chip instead of using the
explicit calls to gpiochip_irqchip_add_nested() and
gpiochip_set_nested_irqchip(). The irqchip is instead
added while adding the gpiochip.

In queue_skb(), skb->data is mapped to streaming DMA on line 850:
dma_map_single(..., skb->data, ...);
Then skb->data is accessed on lines 862 and 863:
tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) |
(skb->data[2] << 8) | (skb->data[3] << 0);
and on lines 893 and 894:
tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) |
(skb->data[2] << 8) | (skb->data[3] << 0);
These accesses may cause data inconsistency between CPU cache and
hardware.
To fix this problem, the calculation result of skb->data is stored in a
local variable before DMA mapping, and then the driver accesses this
local variable instead of skb->data.

This adds full 802.1q VLAN support to the qca8k, allowing the use of
vlan_filtering and more complicated bridging setups than allowed by
basic port VLAN support.
Tested with a number of untagged ports with separate VLANs and then a
trunk port with all the VLANs tagged on it.
v3:
- Pull QCA8K_PORT_VID_DEF changes into separate cleanup patch
- Reverse Christmas tree notation for variable definitions
- Use untagged instead of tagged for consistency
v2:
- Return sensible errnos on failure rather than -1 (rmk)
- Style cleanups based on Florian's feedback
- Silently allow VLAN 0 as device correctly treats this as no tag

commit c8729cac2a11 ("cxgb4: add ethtool n-tuple filter insertion")
has removed checking control key for determining IP address types
for TC-FLOWER rules, which causes all the rules being inserted to
hardware to become IPv6 rule type always. So, add back the check
to select the correct IP address type to extract and hence fix the
correct rule type being inserted to hardware.
Also, ethtool_rx_flow_key doesn't have any control key and instead
directly sets the IPv4/IPv6 address keys. So, explicitly set the
IP address type for ethtool n-tuple filters to reuse the same code.

Getting address and size cells for dma-ranges/ranges parsing is tricky
and shouldn't rely on the node's count_cells() method. The function
starts looking for cells on the parent node, as its supposed to work
with device nodes, which doesn't work when input with bus nodes, as
generally done when parsing ranges.
Add test to catch regressions on that specific quirk as developers will
be tempted to edit it out in favor of the default method.

Pull arm64 and cross-arch updates from Catalin Marinas:
"Here's a slightly wider-spread set of updates for 5.9.
Going outside the usual arch/arm64/ area is the removal of
read_barrier_depends() series from Will and the MSI/IOMMU ID
translation series from Lorenzo.
The notable arm64 updates include ARMv8.4 TLBI range operations and
translation level hint, time namespace support, and perf.
Summary:
- Removal of the tremendously unpopular read_barrier_depends()
barrier, which is a NOP on all architectures apart from Alpha, in
favour of allowing architectures to override READ_ONCE() and do
whatever dance they need to do to ensure address dependencies
provide LOAD -> LOAD/STORE ordering.
This work also offers a potential solution if compilers are shown
to convert LOAD -> LOAD address dependencies into control
dependencies (e.g. under LTO), as weakly ordered architectures will
effectively be able to upgrade READ_ONCE() to smp_load_acquire().
The latter case is not used yet, but will be discussed further at
LPC.
- Make the MSI/IOMMU input/output ID translation PCI agnostic,
augment the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID
bus-specific parameter and apply the resulting changes to the
device ID space provided by the Freescale FSL bus.
- arm64 support for TLBI range operations and translation table level
hints (part of the ARMv8.4 architecture version).
- Time namespace support for arm64.
- Export the virtual and physical address sizes in vmcoreinfo for
makedumpfile and crash utilities.
- CPU feature handling cleanups and checks for programmer errors
(overlapping bit-fields).
- ACPI updates for arm64: disallow AML accesses to EFI code regions
and kernel memory.
- perf updates for arm64.
- Miscellaneous fixes and cleanups, most notably PLT counting
optimisation for module loading, recordmcount fix to ignore
relocations other than R_AARCH64_CALL26, CMA areas reserved for
gigantic pages on 16K and 64K configurations.
- Trivial typos, duplicate words"

Pull unicore32 removal from Mike Rapoport:
"Remove unicore32 support.
The unicore32 port do not seem maintained for a long time now, there
is no upstream toolchain that can create unicore32 binaries and all
the links to prebuilt toolchains for unicore32 are dead. Even
compilers that were available are not supported by the kernel anymore.
Guenter Roeck says:
"I have stopped building unicore32 images since v4.19 since there is
no available compiler that is still supported by the kernel. I am
surprised that support for it has not been removed from the kernel"
However, it's worth pointing out two things:
- Guan Xuetao is still listed as maintainer and asked for the port to
be kept around the last time Arnd suggested removing it two years
ago. He promised that there would be compiler sources (presumably
llvm), but has not made those available since.
- https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both
released in 2016, with patches dated early 2019. These patches
mainly restore a syscall ABI that was never part of mainline Linux
but apparently used in production. qemu-2.8 removed support for
that ABI and newer kernels (4.19+) can no longer be built with the
old toolchain, so apparently there will not be any future updates
to that git tree"

The WARN_*() macros are intended to catch impossible situations
from the SW point of view. They gave a little in case HW<->SW interface
is out-of-sync.
Such out-of-sync scenario can be due to SW errors that are not part
of this flow or because some HW errors, where dump stack won't help
either.
This specific WARN_ON() is useless because mlx5_core code is prepared
to handle such situations and will unfold everything correctly while
providing enough information to the users to understand why FS is not
working.

Allocate nic_info dynamically - n_entries is not constant.
Attach the tunnel offload info only to the uplink representor.
We expect the "main" netdev to be unregistered in switchdev
mode, and there to be only one uplink representor.
Drop the udp_tunnel_drop_rx_info() call, it was not there until
commit b3c2ed21c0bd ("net/mlx5e: Fix VXLAN configuration restore after function reload")
so the device doesn't need it, and core should handle reloads and
reset just fine.
v2:
- don't drop the ndos on reprs, and register info on uplink repr.
v4:
- Move netdev tunnel structure handling to en_main.c

Currently PF and VF representor netdevice carrier is always controlled
by controlling the representor netdevice device state as up/down.
Representor netdevice state change undergoes one or more txq/rxq
destroy/create commands to firmware, skb and its rx buffer allocation,
health reporters creation and more.
Due to this limitation users do not have the ability to just change
the carrier of the non uplink representors without modifying the
device state.
In one use case when the eswitch physical port carrier is down/up,
user needs to update the VF link state to same as physical port
carrier.
Example of updating VF representor carrier state:
$ ip link set enp0s8f0npf0vf0 carrier off
$ ip link set enp0s8f0npf0vf0 carrier on
This enhancement results into VF link state change which is
represented by the VF representor netdevice carrier.
This enables users to modify the representor carrier without modifying
the representor netdevice state.
A simple test is run using [1] to calculate the time difference between
updating carrier vs updating device state (to update just the carrier)
with one VF to simulate 255 VFs.
Time taken to update the carrier using device up/down:
$ time ./calculate.sh dev enp0s8f0npf0vf0
real 0m30.913s
user 0m0.200s
sys 0m11.168s
Time taken to update just the carrier using carrier iproute2 command:
$ time ./calculate.sh carrier enp0s8f0npf0vf0
real 0m2.142s
user 0m0.160s
sys 0m2.021s
Test shows that its better to use carrier on/off user interface to notify
link up/down event to VF compare to device up/down interface, because
carrier user interface delivers the same event 15 times faster.

Pull tpm updates from Jarkko Sakkinen:
"An issue was fixed with the TPM space buffer size. The buffer is used
to store in-TPM objects while swapped out of the TPM for a /dev/tpmrm0
session. The code incorrectly used PAGE_SIZE, which obviously can
vary. With these changes the buffer has a fixed size of 16 kB.
In addition, this contains support for acquiring TPM even log from
TPM2 ACPI table. This method is used by QEMU in particular"

All the LEDs in the queue are RGB, so they should not use multi for

Multicolor is a bit too abstract. Yes, we can have
Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
RGB, and not even RGB-White or RGB-Yellow variants emerged.
Multicolor is not a good fit for RGB LED. It does not really know
about LED color. In particular, there's no way to make LED "white".
Userspace is interested in knowing "this LED can produce arbitrary
color", which not all multicolor LEDs can.
