Pull x86 SGX updates from Borislav Petkov:
- Add support for handling hw errors in SGX pages: poisoning,
recovering from poison memory and error injection into SGX pages
- A bunch of changes to the SGX selftests to simplify and allow of SGX
features testing without the need of a whole SGX software stack

Pull s390 updates from Heiko Carstens:
"Besides all the small improvements and cleanups the most notable part
is the fast vector/SIMD implementation of the ChaCha20 stream cipher,
which is an adaptation of Andy Polyakov's code for the kernel.
Summary:
- add fast vector/SIMD implementation of the ChaCha20 stream cipher,
which mainly adapts Andy Polyakov's code for the kernel
- add status attribute to AP queue device so users can easily figure
out its status
- fix race in page table release code, and and lots of documentation

Pull ARM SoC devicetree updates from Arnd Bergmann:
"As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms. All the
newly supported SoCs belong into existing families this time:
- Qualcomm gets support for two newly announced platforms, both of
which can now work in production environments: the SDX65 5G modem
that can run a minimal Linux on its Cortex-A7 core, and the
Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3 family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two new
SoCs, plus a number of Chromebook variants and phones based on the
Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit chips
out of the box, including a number of ASUS Transformer tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top box
based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
based on BCM4908"

Since irq request is the last thing in the driver probe, it happens
later than the input device registration. This means that there is a
small time window where if the open method is called the driver will
attempt to enable not yet available irq.
Fix that by moving the irq request before the input device registration.

This largely reverts commit 5a7b95fb993ec399c8a685552aa6a8fc995c40bd. It
breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So,
let's remove the code and go back to the drawing board. We keep the
header extension to not break drivers already populating the regulator.
We expect to re-add the code handling it soon.

In the absence of this validation, if the user requests to
configure queues more than the enabled queues, it results in
sending the requested number of queues to the kernel stack
(due to the asynchronous nature of VF response), in which
case the stack might pick a queue to transmit that is not
enabled and result in Tx hang. Fix this bug by
limiting the total number of queues allocated for VF to
active queues of VF.

There was a wrong queues representation in sysfs during
driver's reinitialization in case of online cpus number is
less than combined queues. It was caused by stopped
NetworkManager, which is responsible for calling vsi_open
function during driver's initialization.
In specific situation (ex. 12 cpus online) there were 16 queues
in /sys/class/net/<iface>/queues. In case of modifying queues with
value higher, than number of online cpus, then it caused write
errors and other errors.
Add updating of sysfs's queues representation during driver
initialization.

When loading the i40e driver, it prints a message like: 'The driver for the
device detected a newer version of the NVM image v1.x than expected v1.y.
Please install the most recent version of the network driver.' This is
misleading as the driver is working as expected.
Fix that by removing the second part of message and changing it from

Hide i40e opcode information sent during response to VF in case when
untrusted VF tried to change MAC on the VF interface.
This is implemented by adding an additional parameter 'hide' to the
response sent to VF function that hides the display of error
information, but forwards the error code to VF.
Previously it was not possible to send response with some error code
to VF without displaying opcode information.

__fixed_phy_register"
This reverts commit b45396afa4177f2b1ddfeff7185da733fade1dc3 ("net: phy:
fixed_phy: Fix NULL vs IS_ERR() checking in __fixed_phy_register")
since it prevents any system that uses a fixed PHY without a GPIO
descriptor from properly working:

commit [1] causes missing bitmap updates when there isn't any WriteMostly
devices.
Detailed steps to reproduce by Norbert (which somehow didn't make to lore):
# setup md10 (raid1) with two drives (1 GByte sparse files)
dd if=/dev/zero of=disk1 bs=1024k seek=1024 count=0
dd if=/dev/zero of=disk2 bs=1024k seek=1024 count=0
losetup /dev/loop11 disk1
losetup /dev/loop12 disk2
mdadm --create /dev/md10 --level=1 --raid-devices=2 /dev/loop11 /dev/loop12
# add bitmap (aka write-intent log)
mdadm /dev/md10 --grow --bitmap=internal
echo check > /sys/block/md10/md/sync_action
root:# cat /sys/block/md10/md/mismatch_cnt
0
root:#
# remove member drive disk2 (loop12)
mdadm /dev/md10 -f loop12 ; mdadm /dev/md10 -r loop12
# modify degraded md device
dd if=/dev/urandom of=/dev/md10 bs=512 count=1
# no blocks recorded as out of sync on the remaining member disk1/loop11
root:# mdadm -X /dev/loop11 | grep Bitmap
Bitmap : 16 bits (chunks), 0 dirty (0.0%)
root:#
# re-add disk2, nothing synced because of empty bitmap
mdadm /dev/md10 --re-add /dev/loop12
# check integrity again
echo check > /sys/block/md10/md/sync_action
# disk1 and disk2 are no longer in sync, reads return differend data
root:# cat /sys/block/md10/md/mismatch_cnt
128
root:#
# clean up
mdadm -S /dev/md10
losetup -d /dev/loop11
losetup -d /dev/loop12
rm disk1 disk2
Fix this by moving the WriteMostly check to the if condition for
alloc_behind_master_bio().

Hytera makes a range of digital (DMR) radios. These radios can be
programmed to a allow a computer to control them over Ethernet over USB,
either using NCM or RNDIS.
This commit adds support for RNDIS for Hytera radios. I tested with a
Hytera PD785 and a Hytera MD785G. When these radios are programmed to
set up a Radio to PC Network using RNDIS, an USB interface will be added
with class 2 (Communications), subclass 2 (Abstract Modem Control) and
an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT
RNDIS?").
This patch is similar to the solution of this StackOverflow user, but
that only works for the Hytera MD785:
https://stackoverflow.com/a/53550858
To use the "Radio to PC Network" functionality of Hytera DMR radios, the
radios need to be programmed correctly in CPS (Hytera's Customer
Programming Software). "Forward to PC" should be checked in "Network"
(under "General Setting" in "Conventional") and the "USB Network
Communication Protocol" should be set to RNDIS.

The role of ena_calc_max_io_queue_num() is to return the number
of queues supported by the device, which means the return value
should be >=0.
The function that calls ena_calc_max_io_queue_num(), checks
the return value. If it is 0, it means the device reported
it supports 0 IO queues. This case is considered an error
and is handled by the calling function accordingly.
However the current implementation of ena_calc_max_io_queue_num()
is wrong, since when it detects the device supports 0 IO queues,
it returns -EFAULT.
In such a case the calling function doesn't detect the error,
and therefore doesn't handle it.
This commit changes ena_calc_max_io_queue_num() to return 0
in case the device reported it supports 0 queues, allowing the
calling function to properly handle the error case.
