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)

 - vfio/mlx5 fixes for incorrect return after copy_to_user() fault and
   incorrect buffer freeing (Dan Carpenter)

net/mlx5: fs, add match on ranges API

2022-12-09T00:10:53+00:00

Range is a new flow destination type which allows matching on
a range of values instead of matching on a specific value.

Range flow destination has the following fields:
 - hit_ft: flow table to forward the traffic in case of hit
 - miss_ft: flow table to forward the traffic in case of miss
 - field: which packet characteristic to match on
 - min: minimal value for the selected field
 - max: maximal value for the selected field

Note:
 - In order to match, the value in the packet should meet
   the following criteria: min <= value < max
 - Currently, the only supported field type is L2 packet length

net/mlx5: Add generic getters for other functions caps

2022-12-08T04:09:18+00:00

Downstream patch requires to get other function GENERAL2 caps while
mlx5_vport_get_other_func_cap() gets only one type of caps (general).
Rename it to represent this and introduce a generic implementation
of mlx5_vport_get_other_func_cap().

net/mlx5: Use generic definition for UMR KLM alignment

2022-11-30T05:09:44+00:00

MLX5_UMR_KLM_ALIGNMENT is in units of number of entries, while
MLX5_UMR_MTT_ALIGNMENT (generalized and renamed to
MLX5_UMR_FLEX_ALIGNMENT) is in byte units. This is misleading and
confusing.
Replace this KLM definition with one based on the generic definition.
