Similar to iommu_report_device_fault, this allows IOMMU drivers to report
vIOMMU events from threaded IRQ handlers to user space hypervisors.

This is a reverse search v.s. iommufd_viommu_find_dev, as drivers may want
to convert a struct device pointer (physical) to its virtual device ID for
an event injection to the user space VM.
Again, this avoids exposing more core structures to the drivers, than the
iommufd_viommu alone.

Introduce a new IOMMUFD_OBJ_VEVENTQ object for vIOMMU Event Queue that
provides user space (VMM) another FD to read the vIOMMU Events.
Allow a vIOMMU object to allocate vEVENTQs, with a condition that each
vIOMMU can only have one single vEVENTQ per type.
Add iommufd_veventq_alloc() with iommufd_veventq_ops for the new ioctl.

If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA. The result
of this change is a large savings in resources for older kernels, and a
cleaner driver configuration for the IRDMA=n case for old and new kernels.
Implement this by avoiding enabling the RDMA capability when scanning
hardware capabilities.
Note: Loading the out-of-tree irdma driver in connection to the in-kernel
ice driver, is not supported, and should not be attempted, especially when
disabling IRDMA in the kernel config.

On E800 series hardware, if the start time for a periodic output signal is
programmed into GLTSYN_TGT_H and GLTSYN_TGT_L registers, the hardware logic
locks up and the periodic output signal never starts. Any future attempt to
reprogram the clock function is futile as the hardware will not reset until
a power on.
The ice_ptp_cfg_perout function has logic to prevent this, as it checks if
the requested start time is in the past. If so, a new start time is
calculated by rounding up.
Since commit d755a7e129a5 ("ice: Cache perout/extts requests and check
flags"), the rounding is done to the nearest multiple of the clock period,
rather than to a full second. This is more accurate, since it ensures the
signal matches the user request precisely.
Unfortunately, there is a race condition with this rounding logic. If the
current time is close to the multiple of the period, we could calculate a
target time that is extremely soon. It takes time for the software to
program the registers, during which time this requested start time could
become a start time in the past. If that happens, the periodic output
signal will lock up.
For large enough periods, or for the logic prior to the mentioned commit,
this is unlikely. However, with the new logic rounding to the period and
with a small enough period, this becomes inevitable.
For example, attempting to enable a 10MHz signal requires a period of 100
nanoseconds. This means in the *best* case, we have 99 nanoseconds to
program the clock output. This is essentially impossible, and thus such a
small period practically guarantees that the clock output function will
lock up.
To fix this, add some slop to the clock time used to check if the start
time is in the past. Because it is not critical that output signals start
immediately, but it *is* critical that we do not brick the function, 0.5
seconds is selected. This does mean that any requested output will be
delayed by at least 0.5 seconds.
This slop is applied before rounding, so that we always round up to the
nearest multiple of the period that is at least 0.5 seconds in the future,
ensuring a minimum of 0.5 seconds to program the clock output registers.
Finally, to ensure that the hardware registers programming the clock output
complete in a timely manner, add a write flush to the end of
ice_ptp_write_perout. This ensures we don't risk any issue with PCIe
transaction batching.
Strictly speaking, this fixes a race condition all the way back at the
initial implementation of periodic output programming, as it is
theoretically possible to trigger this bug even on the old logic when
always rounding to a full second. However, the window is narrow, and the
code has been refactored heavily since then, making a direct backport not
apply cleanly.

Use asm_inline for all inline assemblies which make use of the EX_TABLE or
ALTERNATIVE macros.
These macros expand to many lines and the compiler assumes the number of
lines within an inline assembly is the same as the number of instructions
within an inline assembly. This has an effect on inlining and loop
unrolling decisions.
In order to avoid incorrect assumptions use asm_inline, which tells the
compiler that an inline assembly has the smallest possible size.
In order to avoid confusion when asm_inline should be used or not, since a
couple of inline assemblies are quite large: the rule is to always use
asm_inline whenever the EX_TABLE or ALTERNATIVE macro is used. In specific
cases there may be reasons to not follow this guideline, but that should
be documented with the corresponding code.
Using the inline qualifier everywhere has only a small effect on the kernel
image size:
add/remove: 0/10 grow/shrink: 19/8 up/down: 1492/-1858 (-366)
The only location where this seems to matter is load_unaligned_zeropad()
from word-at-a-time.h where the compiler inlines more functions within the
dcache code, which is indeed code where performance matters.

sun8i was using of_get_phy_mode() to set plat_dat->mac_interface, which
defaults to plat_dat->phy_interface when the mac-mode DT property is
not present. As nothing in arch/*/boot/dts sets the mac-mode property,
it is highly likely that these two will be identical, and thus there

The function call “dmaengine_unmap_put(unmap)” was used in an if branch.
The same call was immediately triggered by a subsequent goto statement.
Thus avoid such a call repetition.

The AMD Image Signal Processor GPIO pin control functionality is only
present on AMD platforms with ISP support, and its platform device is
instantiated by the AMD ISP driver. Hence add a dependency on
DRM_AMD_ISP, to prevent asking the user about this driver when
configuring a kernel that does not support the AMD ISP.

If vfs_flush() is called with queue frozen, the queue freeze lock may be
connected with FS internal lock, and lockdep warning can be triggered
because the queue freeze lock is connected with too many global or
sub-system locks.
Fix the warning by moving vfs_fsync() out of loop_update_dio():
- vfs_fsync() is only needed when switching to dio
- only loop_change_fd() and loop_configure() may switch from buffered
IO to direct IO, so call vfs_fsync() directly here. This way is safe
because either loop is in unbound, or new file isn't attached
- for the other two cases of set_status and set_block_size, direct IO
can only become off, so no need to call vfs_fsync()

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure
groups together all the members of the flexible `struct iwl_tx_cmd`
except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct iwl_tx_cmd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
