Merge tag 'for-linus-fwctl' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull fwctl subsystem from Jason Gunthorpe:
"fwctl is a new subsystem intended to bring some common rules and order
to the growing pattern of exposing a secure FW interface directly to
userspace.

Unlike existing places like RDMA/DRM/VFIO/uacce that are exposing a
device for datapath operations fwctl is focused on debugging,
configuration and provisioning of the device. It will not have the
necessary features like interrupt delivery to support a datapath.

This concept is similar to the long standing practice in the "HW" RAID
space of having a device specific misc device to manage the RAID
controller FW. fwctl generalizes this notion of a companion debug and
management interface that goes along with a dataplane implemented in
an appropriate subsystem.

There have been three LWN articles written discussing various aspects
of this:

https://lwn.net/Articles/955001/
https://lwn.net/Articles/969383/
https://lwn.net/Articles/990802/

This includes three drivers to launch the subsystem:

- CXL provides a vendor scheme for executing commands and a way to
learn the 'command effects' (ie the security properties) of such
commands. The fwctl driver allows access to these mechanism within
the fwctl security model

- mlx5 is family of networking products, the driver supports all
current Mellanox HW still receiving FW feature updates. This
includes RDMA multiprotocol NICs like ConnectX and the Bluefield
family of Smart NICs.

- AMD/Pensando Distributed Services card is a multi protocol Smart
NIC with a multi PCI function design. fwctl works on the management
PCI function following a 'command effects' model similar to CXL"
