In order to synchronize changes that can affect the thread callback,
introduce an interface to force a flush of the inject workqueue. The
irqfd pointer is only valid under spinlock, but the workqueue cannot
be flushed under spinlock. Therefore the flush work for the irqfd is
queued under spinlock. The vfio_irqfd_cleanup_wq workqueue is re-used
for queuing this work such that flushing the workqueue is also ordered
relative to shutdown.

Mask operations through config space changes to DisINTx may race INTx
configuration changes via ioctl. Create wrappers that add locking for
paths outside of the core interrupt code.
In particular, irq_type is updated holding igate, therefore testing
is_intx() requires holding igate. For example clearing DisINTx from
config space can otherwise race changes of the interrupt configuration.
This aligns interfaces which may trigger the INTx eventfd into two
camps, one side serialized by igate and the other only enabled while
INTx is configured. A subsequent patch introduces synchronization for
the latter flows.

Currently for devices requiring masking at the irqchip for INTx, ie.
devices without DisINTx support, the IRQ is enabled in request_irq()
and subsequently disabled as necessary to align with the masked status
flag. This presents a window where the interrupt could fire between
these events, resulting in the IRQ incrementing the disable depth twice.
This would be unrecoverable for a user since the masked flag prevents
nested enables through vfio.
Instead, invert the logic using IRQF_NO_AUTOEN such that exclusive INTx
is never auto-enabled, then unmask as required.

The current logic for handling resets is more complicated than it needs
to be. The deferred_reset flag is used to indicate a reset is needed
and the deferred_reset_state is the requested, post-reset, state.
Also, the deferred_reset logic was added to vfio migration drivers to
prevent a circular locking dependency with respect to mm_lock and state
mutex. This is mainly because of the copy_to/from_user() functions(which
takes mm_lock) invoked under state mutex.
Remove all of the deferred reset logic and just pass the requested
next state to pds_vfio_reset() so it can be used for VMM and DSC
initiated resets.
This removes the need for pds_vfio_state_mutex_lock(), so remove that
and replace its use with a simple mutex_unlock().
Also, remove the reset_mutex as it's no longer needed since the
state_mutex can be the driver's primary protector.

It's possible the migration file is accessed after reset when it has
been cleaned up, especially when it's initiated by the device. This is
because the driver doesn't rip out the filep when cleaning up it only
frees the related page structures and sets its local struct
pds_vfio_lm_file pointer to NULL. This can cause a NULL pointer
dereference, which is shown in the example below during a restore after
a device initiated reset:
BUG: kernel NULL pointer dereference, address: 000000000000000c
PF: supervisor read access in kernel mode
PF: error_code(0x0000) - not-present page

Add a disabled flag to the driver's struct pds_vfio_lm_file that gets
set during cleanup. Then make sure to check the flag when the migration
file is accessed via its file_operations. By default this flag will be
false as the memory for struct pds_vfio_lm_file is kzalloc'd, which means
the struct pds_vfio_lm_file is enabled and accessible. Also, since the
file_operations and driver's migration file cleanup happen under the
protection of the same pds_vfio_lm_file.lock, using this flag is thread
safe.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Enable live migration only once the firmware supports PRE_COPY.
PRE_COPY has been supported by the firmware for a long time already [1]
and is required to achieve a low downtime upon live migration.
This lets us clean up some old code that is not applicable those days
while PRE_COPY is fully supported by the firmware.
[1] The minimum firmware version that supports PRE_COPY is 28.36.1010,
it was released in January 2023.
No firmware without PRE_COPY support ever available to users.

Pull block handle updates from Christian Brauner:
"Last cycle we changed opening of block devices, and opening a block
device would return a bdev_handle. This allowed us to implement
support for restricting and forbidding writes to mounted block
devices. It was accompanied by converting and adding helpers to
operate on bdev_handles instead of plain block devices.
That was already a good step forward but ultimately it isn't necessary
to have special purpose helpers for opening block devices internally
that return a bdev_handle.
Fundamentally, opening a block device internally should just be
equivalent to opening files. So now all internal opens of block
devices return files just as a userspace open would. Instead of
introducing a separate indirection into bdev_open_by_*() via struct
bdev_handle bdev_file_open_by_*() is made to just return a struct
file. Opening and closing a block device just becomes equivalent to
opening and closing a file.
This all works well because internally we already have a pseudo fs for
block devices and so opening block devices is simple. There's a few
places where we needed to be careful such as during boot when the
kernel is supposed to mount the rootfs directly without init doing it.
Here we need to take care to ensure that we flush out any asynchronous
file close. That's what we already do for opening, unpacking, and
closing the initramfs. So nothing new here.
The equivalence of opening and closing block devices to regular files
is a win in and of itself. But it also has various other advantages.
We can remove struct bdev_handle completely. Various low-level helpers
are now private to the block layer. Other helpers were simply
removable completely.
A follow-up series that is already reviewed build on this and makes it
possible to remove bdev->bd_inode and allows various clean ups of the
buffer head code as well. All places where we stashed a bdev_handle
now just stash a file and use simple accessors to get to the actual
block device which was already the case for bdev_handle"

Pull KUnit updates from Shuah Khan:
- fix to make kunit_bus_type const
- kunit tool change to Print UML command
- DRM device creation helpers are now using the new kunit device
creation helpers. This change resulted in DRM helpers switching from
using a platform_device, to a dedicated bus and device type used by
kunit. kunit devices don't set DMA mask and this caused regression on
some drm tests as they can't allocate DMA buffers. Fix this problem
by setting DMA masks on the kunit device during initialization.
- KUnit has several macros which accept a log message, which can
contain printf format specifiers. Some of these (the explicit log
macros) already use the __printf() gcc attribute to ensure the format
specifiers are valid, but those which could fail the test, and hence
used __kunit_do_failed_assertion() behind the scenes, did not.
These include: KUNIT_EXPECT_*_MSG(), KUNIT_ASSERT_*_MSG(), and
KUNIT_FAIL()

Currently the sun8i thermal driver will fail to probe if any of the
thermal zones it is registering fails to register with the thermal core.
Since we currently do not define any trip points for the GPU thermal
zones on at least A64 or H5 this means that we have no thermal support
on these platforms:
[ 1.698703] thermal_sys: Failed to find 'trips' node
[ 1.698707] thermal_sys: Failed to find trip points for thermal-sensor id=1
even though the main CPU thermal zone on both SoCs is fully configured.
This does not seem ideal, while we may not be able to use all the zones
it seems better to have those zones which are usable be operational.
Instead just carry on registering zones if we get any non-deferral
error, allowing use of those zones which are usable.
This means that we also need to update the interrupt handler to not
attempt to notify the core for events on zones which we have not
registered, I didn't see an ability to mask individual interrupts and
I would expect that interrupts would still be indicated in the ISR even
if they were masked.

The Allwinner H616 SoC needs to clear a bit in one register in the SRAM
controller, to report reasonable temperature values. On reset, bit 16 in
register 0x3000000 is set, which leads to the driver reporting
temperatures around 200C. Clearing this bit brings the values down to the
expected range. The BSP code does a one-time write in U-Boot, with a
comment just mentioning the effect on the THS, but offering no further
explanation.
To not rely on firmware to set things up for us, add code that queries
the SRAM controller device via a DT phandle link, then clear just this
single bit.

So far we were ORing in some "unknown" value into the THS control
register on the Allwinner H6. This part of the register is not explained
in the H6 manual, but the H616 manual details those bits, and on closer
inspection the THS IP blocks in both SoCs seem very close:
- The BSP code for both SoCs writes the same values into THS_CTRL.
- The reset values of at least the first three registers are the same.
Replace the "unknown" value with its proper meaning: "acquire time",
most probably the sample part of the sample & hold circuit of the ADC,
according to its explanation in the H616 manual.
No functional change, just a macro rename and adjustment.

The Allwinner H616 SoC contains a mysterious bit at register offset 0x0
in the SRAM control block. If bit 16 is set (the reset value), the
temperature readings of the THS are way off, leading to reports about
200C, at normal ambient temperatures. Clearing this bits brings the
reported values down to the expected values.
The BSP code clears this bit in firmware (U-Boot), and has an explicit
comment about this, but offers no real explanation.
Experiments in U-Boot show that register 0x0 has no effect on the SRAM C
visibility: all tested bit settings still allow full read and write
access by the CPU to the whole of SRAM C. Only bit 24 of the register at
offset 0x4 makes all of SRAM C inaccessible by the CPU. So modelling
the THS switch functionality as an SRAM region would not reflect reality.
Since we should not rely on firmware settings, allow other code (the THS
driver) to access this register, by exporting it through the already
existing regmap. This mimics what we already do for the LDO control and
the EMAC register.
To avoid concurrent accesses to the same register at the same time, by
the SRAM switch code and the regmap code, use the same lock to protect
the access. The regmap subsystem allows to use an existing lock, so we
just need to hook in there.

ethtool: ice: Support for RSS settings to GTP
Takeru Hayasaka enables RSS functionality for GTP packets on ice driver
with ethtool.
A user can include TEID and make RSS work for GTP-U over IPv4 by doing the
following:`ethtool -N ens3 rx-flow-hash gtpu4 sde`
In addition to gtpu(4|6), we now support gtpc(4|6),gtpc(4|6)t,gtpu(4|6)e,
gtpu(4|6)u, and gtpu(4|6)d.
gtpc(4|6): Used for GTP-C in IPv4 and IPv6, where the GTP header format does
not include a TEID.
gtpc(4|6)t: Used for GTP-C in IPv4 and IPv6, with a GTP header format that
includes a TEID.
gtpu(4|6): Used for GTP-U in both IPv4 and IPv6 scenarios.
gtpu(4|6)e: Used for GTP-U with extended headers in both IPv4 and IPv6.
gtpu(4|6)u: Used when the PSC (PDU session container) in the GTP-U extended
header includes Uplink, applicable to both IPv4 and IPv6.
gtpu(4|6)d: Used when the PSC in the GTP-U extended header includes Downlink,
for both IPv4 and IPv6.
