For NCT6795D and NCT6796D, the DIMM temperature sources are named
"Agent[01] Dimm [01]" per datasheet. Match names in datasheets to
avoid confusion.

Now that everything is separated, clean up fan and pwm configuration
for NCT6796D. While doing that, take the forgotten configuration register
cre0 into account to determine if AUXFANIN2 (fan5) and AUXFANOUT2 (pwm5)
are connected.

A fan speed tolerance only makes sense if a fan target speed has been
configured in the first place. Otherwise we get odd output such as
fan1_target:0
fan1_tolerance:337500

MAX31725/MAX31726 are local temperature sensors with +/- 0.5 degree
Celsius accuracy and 16-bit (0.00390625 degrees Celsius) resolution.
They have a register mapping and encoding compatible with the lm75

not supported by this patch.

BIOS developer guides refer to Family 15h Models 60h-6fh and Family 15h
Models 70h-7fh. So far the driver only checked for Models 60h and 70h.
However, there are now processors with other model numbers in the same
families. Example is A10-9620P family 15h model 65h. Follow the developer
guides and mask the lower 4 bit of the model number to determine the
registers to use for reading temperatures and temperature limits.

We do not support UPIU of type scsi command yet, while we are using the
job's request and reply pointers to hold the payload. We will look into
it in later patches. We might need to elaborate the raw upiu api for

The UFS host software uses a combination of a host register set and
Transfer Request Descriptors in system memory to communicate with host
controller hardware. In its mmio space, a separate places are assigned
to UTP Transfer Request Descriptor ("utrd") list, and to UTP Task
Management Request Descriptor ("utmrd") list.
The provided API supports utrd-typed requests: nop out and device
management commands. It also supports utmrd-type requests:
task management requests. Other UPIU types are not supported for now.
We utilize the already existing code for tag and task work queues.
That is, all utrd-typed UPIUs are "disguised" as device management
commands. Similarly, the utmrd-typed UPUIs uses the task management
infrastructure.
It is up to the caller to fill the upiu request properly, as it will be
copied without any further input validations.

For now, just provide an API to allocate and remove ufs-bsg node. We
will use this framework to manage ufs devices by sending UPIU
transactions.
For the time being, implements an empty bsg_request() - will add some
more functionality in coming patches.
Nonetheless, we reveal here the protocol we are planning to use: UFS
Transport Protocol Transactions. UFS transactions consist of packets
called UFS Protocol Information Units (UPIU).
There are UPIU’s defined for UFS SCSI commands, responses, data in and
data out, task management, utility functions, vendor functions,
transaction synchronization and control, and more.
By using UPIUs, we get access to the most fine-grained internals of this
protocol, and able to communicate with the device in ways, that are
sometimes beyond the capacity of the ufs driver.
Moreover and as a result, our core structure - ufs_bsg_node has a pretty
lean structure: using upiu transactions that contains the outmost
detailed info, so we don't really need complex constructs to support it.

While fixing an out of bounds array access in known_siginfo_layout
reported by the kernel test robot it became apparent that the same bug
exists in siginfo_layout and affects copy_siginfo_from_user32.
The straight forward fix that makes guards against making this mistake
in the future and should keep the code size small is to just take an
unsigned signal number instead of a signed signal number, as I did to
fix known_siginfo_layout.

The bounds checks in known_siginfo_layout only guards against positive
numbers that are too large, large negative can slip through and
can cause out of bounds accesses.
Ordinarily this is not a concern because early in signal processing
the signal number is filtered with valid_signal which ensures it
is a small positive signal number, but copy_siginfo_from_user
is called before this check is performed.

Therefore fix known_siginfo_layout to take an unsigned signal number
instead of a signed signal number. All valid signal numbers are small
positive numbers so they will not be affected, but invalid negative
signal numbers will now become large positive signal numbers and will
not be used as indices into the sig_sicodes array.
Making the signal number unsigned makes it difficult for similar mistakes to
happen in the future.

mlx5e netdevice used to calculate fragment edges by a call to
mlx5_wq_cyc_get_frag_size(). This calculation did not give the correct
indication for queues smaller than a PAGE_SIZE, (broken by default on
PowerPC, where PAGE_SIZE == 64KB). Here it is replaced by the correct new
calls/API.
Since (TX/RX) Work Queues buffers are fragmented, here we introduce
changes to the API in core driver, so that it gets a stride index and
returns the index of last stride on same fragment, and an additional
wrapping function that returns the number of physically contiguous
strides that can be written contiguously to the work queue.
This obsoletes the following API functions, and their buggy
usage in EN driver:
* mlx5_wq_cyc_get_frag_size()
* mlx5_wq_cyc_ctr2fragix()
The new API improves modularity and hides the details of such
calculation for mlx5e netdevice and mlx5_ib rdma drivers.
New calculation is also more efficient, and improves performance
as follows:
Packet rate test: pktgen, UDP / IPv4, 64byte, single ring, 8K ring size.
Before: 16,477,619 pps
After: 17,085,793 pps
3.7% improvement
Fixes: 3a2f70331226 ("net/mlx5: Use order-0 allocations for all WQ types")
