Add a new function to add exactly one cell. This will be used by the
nvmem layout drivers to add custom cells. In contrast to the
nvmem_add_cells(), this has the advantage that we don't have to assemble
a list of cells on runtime.

If nvmem_add_cells() fails, the whole nvmem_register() will fail
and the cells will then be removed anyway. This is a preparation
to introduce a nvmem_add_one_cell() which can then be used by
nvmem_add_cells().
This is then the same to what nvmem_add_cells_from_table() and
nvmem_add_cells_from_of() do.

struct nvmem_cell_info is used to describe a cell. Thus this should
really be in the nvmem-provider's header. There are two (unused) nvmem
access methods which use the nvmem_cell_info to describe the cell to be
accesses. One can argue, that they will create a cell before accessing,
thus they are both a provider and a consumer.
struct nvmem_cell_info will get used more and more by nvmem-providers,
don't force them to also include the consumer header, although they are
not.

Sometimes a cell can represend multiple values. For example, a base
ethernet address stored in the NVMEM can be expanded into multiple
discreet ones by adding an offset.
For this use case, introduce an index parameter which is then used to
distiguish between values. This parameter will then be passed to the
post process hook which can then use it to create different values
during reading.
At the moment, there is only support for the device tree path. You can
add the index to the phandle, e.g.
&net {
nvmem-cells = <&base_mac_address 2>;
nvmem-cell-names = "mac-address";
};
&nvmem_provider {
base_mac_address: base-mac-address@0 {
#nvmem-cell-cells = <1>;
reg = <0 6>;
};
};

Up until now, a nvmem node didn't have any arguments, so all the device

additional argument for the phandle, for which we need a '#*-cells'

try_to_find_probe_trace_events() uses return error code as ENOENT in two
places.
First place is after open_debuginfo() when opening debuginfo fails and
secondly, after when not finding the probe point.
This function is invoked during BPF load and there are other exit points
in this code path which returns ENOENT. This makes it difficult to
understand the exact reason for exit.
Patches changes the exit code from ENOENT to:
- ENODATA when it fails to find debuginfo
- ENODEV when it fails to find probe point

The Scalable IOV implementation will require notifying the VDCM driver when
an IRQ must be closed. This allows the VDCM to handle releasing stale IRQ
context values and properly reconfigure.
To handle this, introduce a new optional .irq_close callback to the VF
operations structure. This will be implemented by Scalable IOV to handle
the shutdown of the IRQ context.
Since the SR-IOV implementation does not need this, we must check that its
non-NULL before calling it.

When hardware is reset, the VF relies on the VFGEN_RSTAT register to detect
when the VF is finished resetting. This is a tri-state register where 0
indicates a reset is in progress, 1 indicates the hardware is done
resetting, and 2 indicates that the software is done resetting.
Currently the PF driver relies on the device hardware resetting VFGEN_RSTAT
when a global reset occurs. This works ok, but it does mean that the VF
might not immediately notice a reset when the driver first detects that the
global reset is occurring.
This is also problematic for Scalable IOV, because there is no read/write
equivalent VFGEN_RSTAT register for the Scalable VSI type. Instead, the
Scalable IOV VFs will need to emulate this register.
To support this, introduce a new VF operation, clear_reset_state, which is
called when the PF driver first detects a global reset. The Single Root IOV
implementation can just write to VFGEN_RSTAT to ensure it's cleared
immediately, without waiting for the actual hardware reset to begin. The
Scalable IOV implementation will use this as part of its tracking of the
reset status to allow properly reporting the emulated VFGEN_RSTAT to the VF
driver.

The .vsi_rebuild function exists for ice_reset_vf. It is used to release
and re-create the VSI during a single-VF reset.
This function is only called when we need to re-create the VSI, and not
when rebuilding an existing VSI. This makes the single-VF reset process
different from the process used to restore functionality after a
hardware reset such as the PF reset or EMP reset.
When we add support for Scalable IOV VFs, the implementation will be very
similar. The primary difference will be in the fact that each VF type uses
a different underlying VSI type in hardware.
Move the common functionality into a new ice_vf_recreate VSI function. This
will allow the two IOV paths to share this functionality. Rework the
.vsi_rebuild vf_op into .create_vsi, only performing the task of creating a
new VSI.
This creates a nice dichotomy between the ice_vf_rebuild_vsi and
ice_vf_recreate_vsi, and should make it more clear why the two flows atre
distinct.

Refactor by introducing a new wrapper function, ice_vf_post_vsi_rebuild

IOV. Move the ice_vf_rebuild_host_cfg and ice_vf_set_initialized calls into

The ice_vsi_alloc and ice_vsi_cfg functions are used together to allocate
and configure a new VSI, called as part of the ice_vsi_setup function.
In the future with the addition of the subfunction code the ice driver
will want to be able to allocate a VSI while delaying the configuration to
a later point of the port activation.
Currently this requires that the port code know what type of VSI should
be allocated. This is required because ice_vsi_alloc assigns the VSI type.
Refactor the ice_vsi_alloc and ice_vsi_cfg functions so that VSI type
assignment isn't done until the configuration stage. This will allow the
devlink port addition logic to reserve a VSI as early as possible before
the type of the port is known. In this way, the port add can fail in the
event that all hardware VSI resources are exhausted.
Since the ice_vsi_cfg function already takes the ice_vsi_cfg_params
structure, this is relatively straight forward.

The ice_vsi_setup function, ice_vsi_alloc, and ice_vsi_cfg functions have
grown a large number of parameters. These parameters are used to initialize
a new VSI, as well as re-configure an existing VSI
Any time we want to add a new parameter to this function chain, even if it
will usually be unset, we have to change many call sites due to changing
the function signature.
A future change is going to refactor ice_vsi_alloc and ice_vsi_cfg to move
the VSI configuration and initialization all into ice_vsi_cfg.
Before this, refactor the VSI setup flow to use a new ice_vsi_cfg_params
structure. This will contain the configuration (mainly pointers) used to
initialize a VSI.
Pass this from ice_vsi_setup into the related functions such as
ice_vsi_alloc, ice_vsi_cfg, and ice_vsi_cfg_def.
Introduce a helper, ice_vsi_to_params to convert an existing VSI to the
parameters used to initialize it. This will aid in the flows where we
rebuild an existing VSI.
Since we also pass the ICE_VSI_FLAG_INIT to more functions which do not
need (or cannot yet have) the VSI parameters, lets make this clear by
renaming the function parameter to vsi_flags and using a u32 instead of a
signed integer. The name vsi_flags also makes it clear that we may extend
the flags in the future.
This change will make it easier to refactor the setup flow in the future,
and will reduce the complexity required to add a new parameter for
configuration in the future.

The vsi->vf pointer gets assigned early on during ice_vsi_alloc. Several
functions currently take a VF pointer, but they can just use the existing
vsi->vf pointer as needed. Modify these functions to drop the unnecessary
VF parameter.
Note that ice_vsi_cfg is not changed as a following change will refactor so
that the VF pointer is assigned during ice_vsi_cfg rather than
ice_vsi_alloc.

Since commit 1d2e32275de7 ("ice: split ice_vsi_setup into smaller

Extend the usage of function ice_get_vf_vsi(vf) in multiple places

Using __irq_domain_alloc_irqs() is an unnecessary complexity. Use
irq_domain_alloc_irqs(), which is simpler and makes the code more

An interrupted dma_fence_wait() becomes an -ERESTARTSYS returned
to userspace ioctl(DRM_IOCTL_VIRTGPU_EXECBUFFER) calls, prompting to
retry the ioctl(), but the passed exbuf->fence_fd has been reset to -1,
making the retry attempt fail at sync_file_get_fence().
The uapi for DRM_IOCTL_VIRTGPU_EXECBUFFER is changed to retain the
passed value for exbuf->fence_fd when returning anything besides a
successful result from the ioctl.

When checking for ID_AA64SMFR0_EL1.SMEver, __check_override assumes
that the ID_AA64SMFR0_EL1 value is in x1, and the intent of the code
is to reuse value read a few lines above.
However, as the comment says at the beginning of the macro, x1 will
be clobbered, and the checks always fails.
The easiest fix is just to reload the id register before checking it.
