Speculative prefetches from CPU to GPU memory until the GPU is
ready after reset can cause harmless corrected RAS events to
be logged on Grace systems. It is thus preferred that the
mapping not be re-established until the GPU is ready post reset.
The GPU readiness can be checked through BAR0 registers similar
to the checking at the time of device probe.
It can take several seconds for the GPU to be ready. So it is
desirable that the time overlaps as much of the VM startup as
possible to reduce impact on the VM bootup time. The GPU
readiness state is thus checked on the first fault/huge_fault
request or read/write access which amortizes the GPU readiness
time.
The first fault and read/write checks the GPU state when the
reset_done flag - which denotes whether the GPU has just been
reset. The memory_lock is taken across map/access to avoid
races with GPU reset.
Also check if the memory is enabled, before waiting for GPU
to be ready. Otherwise the readiness check would block for 30s.
Lastly added PM handling wrapping on read/write access.

Introduce a new flag reset_done to notify that the GPU has just
been reset and the mapping to the GPU memory is zapped.
Implement the reset_done handler to set this new variable. It
will be used later in the patches to wait for the GPU memory
to be ready before doing any mapping or access.

Split the function that check for the GPU device being ready on
the probe.
Move the code to wait for the GPU to be ready through BAR0 register
reads to a separate function. This would help reuse the code.
This also fixes a bug where the return status in case of timeout
gets overridden by return from pci_enable_device. With the fix,
a timeout generate an error as initially intended.

NVIDIA's Grace based systems have large device memory. The device
memory is mapped as VM_PFNMAP in the VMM VMA. The nvgrace-gpu
module could make use of the huge PFNMAP support added in mm [1].
To make use of the huge pfnmap support, fault/huge_fault ops
based mapping mechanism needs to be implemented. Currently nvgrace-gpu
module relies on remap_pfn_range to do the mapping during VM bootup.
Replace it to instead rely on fault and use vfio_pci_vmf_insert_pfn
to setup the mapping.
Moreover to enable huge pfnmap, nvgrace-gpu module is updated by
adding huge_fault ops implementation. The implementation establishes
mapping according to the order request. Note that if the PFN or the
VMA address is unaligned to the order, the mapping fallbacks to
the PTE level.

fill_sg_entry() splits large DMA buffers into multiple scatter-gather
entries, each holding up to UINT_MAX bytes. When calculating the DMA
address for entries beyond the second one, the expression (i * UINT_MAX)
causes integer overflow due to 32-bit arithmetic.
This manifests when the input arg length >= 8 GiB results in looping for
i >= 2.
Fix by casting i to dma_addr_t before multiplication.

Thanks to a device generating an ACS violation during bus reset,
lockdep reported the following circular locking issue:
CPU0: SET_IRQS (MSI/X): holds igate, acquires memory_lock
CPU1: HOT_RESET: holds memory_lock, acquires pci_bus_sem
CPU2: AER: holds pci_bus_sem, acquires igate
This results in a potential 3-way deadlock.
Remove the pci_bus_sem->igate leg of the triangle by using RCU
to peek at the eventfd rather than locking it with igate.

In max16065_current_show, data->curr_sense is read twice: once for the
error check and again for the calculation. Since
i2c_smbus_read_byte_data returns negative error codes on failure, if the
data changes to an error code between the check and the use, ADC_TO_CURR
results in an incorrect calculation.
Read data->curr_sense into a local variable to ensure consistency. Note
that data->curr_gain is constant and safe to access directly.
This aligns max16065_current_show with max16065_input_show, which
already uses a local variable for the same reason.

The macros FAN_FROM_REG and TEMP_FROM_REG evaluate their arguments
multiple times. When used in lockless contexts involving shared driver
data, this causes Time-of-Check to Time-of-Use (TOCTOU) race
conditions.
Convert the macros to static functions. This guarantees that arguments
are evaluated only once (pass-by-value), preventing the race
conditions.
Adhere to the principle of minimal changes by only converting macros
that evaluate arguments multiple times and are used in lockless
contexts.

Refactor auto buffer register code and prepare for supporting batch IO
feature, and the main motivation is to put 'ublk_io' operation code
together, so that per-io lock can be applied for the code block.
The key changes are:
- Rename ublk_auto_buf_reg() as ublk_do_auto_buf_reg()
- Introduce an enum `auto_buf_reg_res` to represent the result of
the buffer registration attempt (FAIL, FALLBACK, OK).
- Split the existing `ublk_do_auto_buf_reg` function into two:
- `__ublk_do_auto_buf_reg`: Performs the actual buffer registration
and returns the `auto_buf_reg_res` status.
- `ublk_do_auto_buf_reg`: A wrapper that calls the internal function
and handles the I/O preparation based on the result.
- Introduce `ublk_prep_auto_buf_reg_io` to encapsulate the logic for
preparing the I/O for completion after buffer registration.
- Pass the `tag` directly to `ublk_auto_buf_reg_fallback` to avoid
recalculating it.
This refactoring makes the control flow clearer and isolates the different
stages of the auto buffer registration process.

Add `union ublk_io_buf` for naming the anonymous union of struct ublk_io's
addr and buf fields, meantime apply it to `struct ublk_io` for storing either
ublk auto buffer register data or ublk server io buffer address.
The union uses clear field names:
- `addr`: for regular ublk server io buffer addresses
- `auto_reg`: for ublk auto buffer registration data
This eliminates confusing access patterns and improves code readability.

Discovered by Atuin - Automated Vulnerability Discovery Engine.
In ac_ioctl, the validation of IndexCard and the check for a valid
RamIO pointer are skipped when cmd is 6. However, the function
unconditionally executes readb(apbs[IndexCard].RamIO + VERS) at the
end.
If cmd is 6, IndexCard may reference a board that does not exist
(where RamIO is NULL), leading to a NULL pointer dereference.
Fix this by skipping the readb access when cmd is 6, as this
command is a global information query and does not target a specific
board context.

The error status mask for a type 3/4 subspace is used for reading the
error status, and the bitwise inverse is used for clearing the error
with the intent being to preserve any of the non-error bits. However,
we were previously applying the mask to extract the status and then
applying the inverse to the result which ended up clearing all bits.
Instead, store the inverse mask in the preserve mask and then use that
on the original value read from the error status so that only the error
is cleared.

mtk_gpueb_mbox_ops should be declared static. However, due to its const
nature, this specifier was missed, as it compiled fine without it and
with no warning by the compiler.
arc-linux-gcc (GCC) 12.5.0 doesn't seem to like it however, so add the
static to fix that.

GCE can only fetch the command buffer address from a 32-bit register.
Some SoCs support a 35-bit command buffer address for GCE, which
requires a right shift of 3 bits before setting the address into
the 32-bit register. A comment has been added to the header of
cmdq_get_shift_pa() to explain this requirement.
To prevent the GCE command buffer address from being DMA mapped beyond
its supported bit range, the DMA bit mask for the device is set during
initialization.
Additionally, to ensure the correct shift is applied when setting or
reading the register that stores the GCE command buffer address,
new APIs, cmdq_convert_gce_addr() and cmdq_revert_gce_addr(), have
been introduced for consistent operations on this register.
The variable type for the command buffer address has been standardized
to dma_addr_t to prevent handling issues caused by type mismatches.

On TI K3 devices, the mailbox resides in the Always-On power domain
(LPSC_main_alwayson) and is shared among multiple processors. The
mailbox is not solely exclusive to Linux.
Currently, the suspend path checks all FIFO queues for pending messages
and blocks suspend if any are present. This behavior is unnecessary for
K3 devices, since some of the FIFOs are used for RTOS<->RTOS
communication and are independent of Linux.
For FIFOs used in Linux<->RTOS communication, any pending message would
trigger an interrupt, which naturally prevents suspend from completing.
Hence, there is no need for the mailbox driver to explicitly check for
pending messages on K3 platforms.
Introduce a device match flag to indicate whether the mailbox instance
is exclusive to Linux, and skip the pending message check for
non-exclusive instances (such as in K3).

Currently the user can write anything into the drm.panic_screen modparam,
either at runtime via sysfs, or as a kernel boot time argument. Invalid
strings will be silently accepted and ignored at use time by defaulting to
the 'user' panic mode.
Let instead add some validation in order to have immediate feedback when
something has been mistyped, or not compiled in.
For example during kernel boot:
Booting kernel: `bsod' invalid for parameter `drm.panic_screen'
Or at runtime:
# echo -n bsod > /sys/module/drm/parameters/panic_screen
-bash: echo: write error: Invalid argument
Change of behavior is that when invalid mode is attempted to be
configured, currently the code will default to the 'user' mode, while with
this change the code will ignore it, and default to the mode set at kernel
build time via CONFIG_DRM_PANIC_SCREEN.
While at it lets also fix the module parameter description to include all
compiled in modes.

DSDT the GPIO controller is compatible with 2K2000, but it fails to

Using BYTE_CTRL_MODE also makes those 2K3000 GPIOs work.

Discovered by Atuin - Automated Vulnerability Discovery Engine.
The 'len' variable is calculated as 'min(32, trans->len + 1)',
which includes the 1-byte command header.
When copying data from 'trans->tx_buf' to 'ch341->tx_buf + 1', using 'len'
as the length is incorrect because:
1. It causes an out-of-bounds read from 'trans->tx_buf' (which has size
'trans->len', i.e., 'len - 1' in this context).
2. It can cause an out-of-bounds write to 'ch341->tx_buf' if 'len' is
CH341_PACKET_LENGTH (32). Writing 32 bytes to ch341->tx_buf + 1
overflows the buffer.
Fix this by copying 'len - 1' bytes.

A client of cs_dsp does not necessarily need to implement any of the
optional callbacks in struct cs_dsp_client_ops, so allow the client_ops
pointer to be NULL.
This has been done by pointing client_ops at a default empty
cs_dsp_client_ops. It keeps the code cleaner by avoiding having to add
double nested NULL checks everywhere one of these callbacks is called.
