Expose NIC temperature by implementing hwmon kernel API, which turns
current thermal zone kernel API to redundant.
For each one of the supported and exposed thermal diode sensors, expose
the following attributes:
1) Input temperature.
2) Highest temperature.
3) Temperature label:
Depends on the firmware capability, if firmware doesn't support
sensors naming, the fallback naming convention would be: "sensorX",
where X is the HW spec (MTMP register) sensor index.
4) Temperature critical max value:
refers to the high threshold of Warning Event. Will be exposed as
`tempY_crit` hwmon attribute (RO attribute). For example for
ConnectX5 HCA's this temperature value will be 105 Celsius, 10
degrees lower than the HW shutdown temperature).
5) Temperature reset history: resets highest temperature.
For example, for dualport ConnectX5 NIC with a single IC thermal diode
sensor will have 2 hwmon directories (one for each PCI function)
under "/sys/class/hwmon/hwmon[X,Y]".
Listing one of the directories above (hwmonX/Y) generates the
corresponding output below:
$ grep -H -d skip . /sys/class/hwmon/hwmon0/*
Output

Added a new event handler to firmware sync reset, which is used to
support firmware sync reset flow on smart NIC. Adding this new stage to
the flow enables the firmware to ensure host PFs unload before ECPFs
unload, to avoid race of PFs recovery.
If firmware sends sync_reset_unload event to driver the driver should
unload and close all HW resources of the function. Once the driver
finishes unloading part, it can't get any more events from firmware as
event queues are closed, so it polls the reset state field to know when
to continue to next stage of the sync reset flow.
Added capability bit for supporting sync_reset_unload event.

Pull VFIO updates from Alex Williamson:
- Replace deprecated git://github.com link in MAINTAINERS (Palmer
Dabbelt)
- Simplify vfio/mlx5 with module_pci_driver() helper (Shang XiaoJing)
- Drop unnecessary buffer from ACPI call (Rafael Mendonca)
- Correct latent missing include issue in iova-bitmap and fix support
for unaligned bitmaps. Follow-up with better fix through refactor
(Joao Martins)
- Rework ccw mdev driver to split private data from parent structure,
better aligning with the mdev lifecycle and allowing us to remove a
temporary workaround (Eric Farman)
- Add an interface to get an estimated migration data size for a
device, allowing userspace to make informed decisions, ex. more
accurately predicting VM downtime (Yishai Hadas)
- Fix minor typo in vfio/mlx5 array declaration (Yishai Hadas)
- Simplify module and Kconfig through consolidating SPAPR/EEH code and
config options and folding virqfd module into main vfio module (Jason
Gunthorpe)
- Fix error path from device_register() across all vfio mdev and sample
drivers (Alex Williamson)
- Define migration pre-copy interface and implement for vfio/mlx5
devices, allowing portions of the device state to be saved while the
device continues operation, towards reducing the stop-copy state size
(Jason Gunthorpe, Yishai Hadas, Shay Drory)
- Implement pre-copy for hisi_acc devices (Shameer Kolothum)
- Fixes to mdpy mdev driver remove path and error path on probe (Shang
XiaoJing)
