In ublk_queue_rq(), ubq->canceling has to be handled after ->fail_io and
->force_abort are dealt with, otherwise the request may not be failed
when deleting disk.
Add comment on this usage.

Now ublk driver depends on `ubq->canceling` for deciding if the request
can be dispatched via uring_cmd & io_uring_cmd_complete_in_task().
Once ubq->canceling is set, the uring_cmd can be done via ublk_cancel_cmd()
and io_uring_cmd_done().
So set ubq->canceling when queue is frozen, this way makes sure that the
flag can be observed from ublk_queue_rq() reliably, and avoids
use-after-free on uring_cmd.

When using dm-integrity in standalone mode with a keyed hmac algorithm,
integrity tags are calculated and verified internally.
Using plain memcmp to compare the stored and computed tags may leak the
position of the first byte mismatch through side-channel analysis,
allowing to brute-force expected tags in linear time (e.g., by counting
single-stepping interrupts in confidential virtual machine environments).

If execute_location()'s memcpy of do_nothing() gets inlined and unrolled
by the compiler, it copies one word at a time:
mov 0x0(%rip),%rax R_X86_64_PC32 .text+0x1374
mov %rax,0x38(%rbx)
mov 0x0(%rip),%rax R_X86_64_PC32 .text+0x136c
mov %rax,0x30(%rbx)
...
Those .text references point to the middle of the function, causing
objtool to complain about their lack of ENDBR.
Prevent that by resolving the function pointer at runtime rather than
build time. This fixes the following warning:

commit 8a7d12d674ac ("net: usb: usbnet: fix name regression") assumed
that local addresses always came from the kernel, but some devices hand
out local mac addresses so we ended up with point-to-point devices with
a mac set by the driver, renaming to eth%d when they used to be named
usb%d.
Userspace should not rely on device name, but for the sake of stability
restore the local mac address check portion of the naming exception:
point to point devices which either have no mac set by the driver or
have a local mac handed out by the driver will keep the usb%d name.
(some USB LTE modems are known to hand out a stable mac from the locally
administered range; that mac appears to be random (different for
mulitple devices) and can be reset with device-specific commands, so
while such devices would benefit from getting a OUI reserved, we have
to deal with these and might as well preserve the existing behavior
to avoid breaking fragile openwrt configurations and such on upgrade.)

When hw-gro is enabled, the maximum number of header entries that are
needed per wqe (hd_per_wqe) is calculated based on the size of the
reservations among other parameters.
Miscalculation of the size of reservations leads to incorrect
calculation of hd_per_wqe as 0, particularly in the case of large page
size like in aarch64, this prevents the SHAMPO header from being
correctly initialized in the device, ultimately causing the following
cqe err that indicates a violation of PD.
mlx5_core 0000:00:08.0 eth2: ERR CQE on RQ: 0x1180
mlx5_core 0000:00:08.0 eth2: Error cqe on cqn 0x510, ci 0x0, qn 0x1180, opcode 0xe, syndrome 0x4, vendor syndrome 0x32

Use the correct formula for calculating the size of reservations,
precisely it shouldn't be dependent on page size, instead use the
correct multiply of MLX5E_SHAMPO_WQ_BASE_RESRV_SIZE.

Calling verity_verify_io in bh for IO of all sizes is not suitable for
embedded devices. From our tests, it can improve the performance of 4K
synchronise random reads.
For example:
./fio --name=rand_read --ioengine=psync --rw=randread --bs=4K \
--direct=1 --numjobs=8 --runtime=60 --time_based --group_reporting \
--filename=/dev/block/mapper/xx-verity
But it will degrade the performance of 512K synchronise sequential reads
on our devices.
For example:
./fio --name=read --ioengine=psync --rw=read --bs=512K --direct=1 \
--numjobs=8 --runtime=60 --time_based --group_reporting \
--filename=/dev/block/mapper/xx-verity
A parameter array is introduced by this change. And users can modify the
default config by /sys/module/dm_verity/parameters/use_bh_bytes.
The default limits for NONE/RT/BE is set to 8192.
The default limits for IDLE is set to 0.
Call verity_verify_io directly when verity_end_io is not in hardirq.

Depending on the secureboot signature on EFI\BOOT\BOOTX86.EFI the
Lenovo Yoga Tab 3 UEFI will switch its OSID ACPI variable between
1 (Windows) and 4 (Android(GMIN)).
In Windows mode a GPIO event handler gets installed for GPO1 pin 5,
causing Linux' x86-android-tables code which deals with the general
brokenness of this device's ACPI tables to fail to probe with:
[ 17.853705] x86_android_tablets: error -16 getting GPIO INT33FF:01 5
[ 17.859623] x86_android_tablets x86_android_tablets: probe with driver

Intel Over-Clocking Watchdogs are described in ACPI tables by both the
generic PNP0C02 _CID and their ACPI _HID. The presence of the _CID then
causes the PNP scan handler to attach to the watchdog, preventing the
actual watchdog driver from binding. Address this by adding the ACPI
_HIDs to the list of non-PNP devices, so that the PNP scan handler is
bypassed.
Note that these watchdogs can be described by multiple _HIDs for what
seems to be identical hardware. This commit is not a complete list of
all the possible watchdog ACPI _HIDs.

Driver use devm APIs to manage clk/irq/resources and register the spi
controller, but the legacy remove function will be called first during
device detach and trigger kernel panic. Drop the remove function and use
devm_add_action_or_reset() for driver cleanup to ensure the release
sequence.
Trigger kernel panic on i.MX8MQ by
echo 30bb0000.spi >/sys/bus/platform/drivers/fsl-quadspi/unbind
