TCP transport relies on the routing table to determine which source
address and interface to use when making a connection. Currently, there
is no way to tell from userspace where a connection was made. This
patch exposes the actual source address using a new field named
"src_addr=" in the "address" attribute.
This is needed to diagnose and identify connectivity issues. With the
source address we can infer the interface associated with each
connection.
This was tested with nvme-cli 2.0 to verify it does not have any
adverse effect. The new "src_addr=" field will simply be displayed in
the output of the "list-subsys" or "list -v" commands as shown here.
$ nvme list-subsys

kmap() is being deprecated in favor of kmap_local_page().[1]
There are two main problems with kmap(): (1) It comes with an overhead as
mapping space is restricted and protected by a global lock for
synchronization and (2) it also requires global TLB invalidation when the
kmap’s pool wraps and it might block when the mapping space is fully
utilized until a slot becomes available.
The pages which will be mapped are allocated in nvmet_tcp_map_data(),
using the GFP_KERNEL flag. This assures that they cannot come from
HIGHMEM. This imply that a straight page_address() can replace the kmap()
of sg_page(sg) in nvmet_tcp_map_pdu_iovec(). As a side effect, we might
also delete the field "nr_mapped" from struct "nvmet_tcp_cmd" because,
after removing the kmap() calls, there would be no longer any need of it.
In addition, there is no reason to use a kvec for the command receive
data buffers iovec, use a bio_vec instead and let iov_iter handle the
buffer mapping and data copy.
Test with blktests on a QEMU/KVM x86_32 VM, 6GB RAM, booting a kernel with
HIGHMEM64GB enabled.

The largest allowed transfer is 4MB, which can use at most 1025 PRPs.
Each PRP is 8 bytes, so the maximum number of 4k nvme pages needed for
the iod_list is 3, which fits in an 's8' type.
While modifying this field, change the name to "nr_allocations" to
better represent that this is referring to the number of units allocated
from a dma_pool.
Also introduce a BUILD_BUG_ON to ensure we never accidently increase the
largest transfer limit beyond 127 chained prp lists.

On reconnect, the number of queues might have changed.
In the case where we have more queues available than previously we try
to access queues which are not initialized yet.
The other case where we have less queues than previously, the
connection attempt will fail because the target doesn't support the
old number of queues and we end up in a reconnect loop.
Thus, only start queues which are currently present in the tagset
limited by the number of available queues. Then we update the tagset

Where:
G = 60, H = 200, cal5 = 4094, J = -0.1, F = frequency clock in MHz
Series 6 has a slightly different equation:
T = G + H * (n / cal5 - 0.5)
and a different set of coefficients:
G = 57.4, H = 249.4, cal5 = 4096
This change supports equation and coefficients for both series.
(for series 6, J is set to 0).
The series is determined according to “moortec,ts-series” property in

If absent, series 5 is assumed to be the default.

In code, the G, H and J coefficients are multiplied by a factor of 1000

Extend aquacomputer_d5next driver to expose various hardware
sensors of the Aquacomputer High Flow Next flow sensor, which
communicates through a proprietary USB HID protocol.
The High Flow Next exposes +5V voltages, water quality, conductivity
and flow readings. A temperature sensor can be connected to it, in
which case it provides its reading and an estimation of the
dissipated/absorbed power in the liquid cooling loop.
Additionally, serial number and firmware version are exposed through
debugfs.
Registry offsets were discovered and tested by users on Github [1] [2].

- calls clk_prepare_enable() and registers what is needed in order to

a dedicated function used with devm_add_action_or_reset().

When dell-smm-hwmon is loaded on a machine with a buggy BIOS
with the option "force" being enabled, it wrongly prints
that the buggy features where disabled. This may cause
users to wrongly assume that the driver still protects them
from these BIOS bugs even with "force" being enabled.
Replace the messages with two messages each which are depending
on the value of the "force" parameter. The messages which are
being printed when "force" is not set use dev_notice() instead
of dev_warn() since they only serve as a notice.

Add support for reading virtual temperature sensors for the D5 Next, Octo,
Quadro and Farbwerk 360.
Virtual temperature sensors are written to the device by the user, pulling
from an arbitrary value source. Writing to them is not yet reverse
engineered, so the only way to set them for now is to use the official
software.

This driver utilises a WMI interface found in AMD 500 series ASUS boards,
to read EC registers. But it turned out that ASUS abandoned the
interface, as it disappeared from Intel 600 series boards. Additionally,
the WMI interface was incredibly slow. Therefore this driver was deprecated
in favor of the asus_ec_sensors driver, which supports more boards, more
sensors, and is faster.

In gsc_hwmon_get_devtree_pdata(), we should call of_node_get() before
the of_find_compatible_node() which will automatically call
of_node_put() for the 'from' argument.

The offsets for setting speeds of fans connected to Quadro are off by one.
Set them to their correct values.
The offsets as shown point to registers for setting the fan control mode,
which will be explored in future patches, but slipped in here. When
setting fan speeds, the resulting values were overlapping, which made the
fans still run in my initial testing.

On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force
threaded and runs with interrupts enabled. The invocation of
generic_handle_irq() with interrupts enabled triggers a lockdep warning due
to a non-irq safe lock acquisition.
Instead of disabling interrupts on the driver level, use
generic_handle_domain_irq_safe().
