Move the randomize_va_space variable together with all its sysctl table
elements into memory.c. Register it to the "kernel" directory by
adding it to the subsys initialization calls
This is part of a greater effort to move ctl tables into their
respective subsystems which will reduce the merge conflicts in
kernel/sysctl.c.

Add support for the TI TPS65214 PMIC with the addition of an id_table,
separate TPS65214 template_chip, and device-specific _change_direction
functions.
- Use platform_get_device_id() to assign dev-specific information.
- Use different change_direction() functions since TPS65214's GPIO
configuration bits are changeable during device operation through bit
GPIO_CONFIG in GENERAL_CONFIG register.
- Remove MODULE_ALIAS since it is now generated by MODULE_DEVICE_TABLE.

Currently there isn't a clear layer separation between the counters and
the steering code, whereas the steering code is doing redundant access
to the counter struct.
Separate the fs.c and counters.c, where fs code won't access or be
aware of counter structs but only the objects it needs.
As a result, move mlx5_rdma_counter struct from the header file to be
an internal struct for the counters file only.

As part of this enhancement, allow the creation of an MKEY associated
with a DMA handle.
Additional notes:
MKEYs with TPH (i.e. TLP Processing Hints) attributes are currently not
UMR-capable unless explicitly enabled by firmware or hardware.
Therefore, to maintain such MKEYs in the MR cache, the TPH fields have
been added to the rb_key structure, with a dedicated hash bucket.
The ability to bypass the kernel verbs flow and create an MKEY with TPH
attributes using DEVX has been restricted. TPH must follow the standard
InfiniBand flow, where a DMAH is created with the appropriate security
checks and management mechanisms in place.
DMA handles are currently not supported in conjunction with On-Demand
Paging (ODP).
Re-registration of memory regions originally created with TPH attributes
is currently not supported.

This patch introduces support for allocating and deallocating the DMAH
object.
Further details:
----------------
The DMAH API is exposed to upper layers only if the underlying device
supports TPH.
It uses the mlx5_core steering tag (ST) APIs to get a steering tag index
based on the provided input.
The obtained index is stored in the device-specific mlx5_dmah structure
for future use.
Upcoming patches in the series will integrate the allocated DMAH into
the memory region (MR) registration process.

Introduce a new DMA handle (DMAH) object along with its corresponding
allocation and deallocation APIs.
This DMAH object encapsulates attributes intended for use in DMA
transactions.
While its initial purpose is to support TPH functionality, it is
designed to be extensible for future features such as DMA PCI multipath,
PCI UIO configurations, PCI traffic class selection, and more.
Further details:
----------------
We ensure that a caller requesting a DMA handle for a specific CPU ID is
permitted to be scheduled on it. This prevent a potential security issue
where a non privilege user may trigger DMA operations toward a CPU that
it's not allowed to run on.
We manage reference counting for the DMAH object and its consumers
(e.g., memory regions) as will be detailed in subsequent patches in the
series.

From Yishai:
This patch series introduces a new DMA Handle (DMAH) object, along with
corresponding APIs for its allocation and deallocation.
The DMAH object encapsulates attributes relevant for DMA transactions.
While initially intended to support TLP Processing Hints (TPH) [1], the
design is extensible to accommodate future features such as PCI
multipath for DMA, PCI UIO configurations, traffic class selection, and
more.
Additionally, we introduce a new ioctl method on the MR object:
UVERBS_METHOD_REG_MR.
This method consolidates multiple reg_mr variants under a single
user-space ioctl interface, supporting: ibv_reg_mr(), ibv_reg_mr_iova(),
ibv_reg_mr_iova2() and ibv_reg_dmabuf_mr(). It also enables passing a
DMA handle as part of the registration process.
Throughout the patch series, the following DMAH-related stuff can also
be observed in the IB layer:
- Association with a CPU ID and its memory type, for use with Steering
Tags [2].
- Inclusion of Processing Hints (PH) data for TPH functionality [3].
- Enforces security by ensuring that only tasks allowed to run on a
given CPU may request a DMA handle for it.
- Reference counting for DMAH life cycle management and safe usage
across memory regions.
mlx5 driver implementation:
--------------------------
The series includes implementation of the above functionality in the
mlx5 driver.
In mlx5_core:
- Enables TPH over PCIe when both firmware and OS support it.
- Manages Steering Tags and corresponding indices by writing tag values
to the PCI configuration space.
- Exposes APIs to upper layers (e.g., mlx5_ib) to enable the PCIe TPH
functionality.
In mlx5_ib:
- Adds full support for DMAH operations.
- Utilizes mlx5_core's Steering Tag APIs to derive tag indices from
input.
- Stores the resulting index in a mlx5_dmah structure for use during
MKEY creation with a DMA handle.
- Adds support for allowing MKEYs to be created in conjunction with DMA
handles.
Additional details are provided in the commit messages.

TLP Processing Hints (TPH)
--------------------------
TLP Processing Hints is an optional feature that provides hints in
Request TLP headers to facilitate optimized processing of Requests that
target Memory Space. These Processing Hints enable the system hardware
(e.g., the Root Complex and/ or Endpoints) to optimize platform
resources such as system and memory interconnect on a per TLP basis.
Steering Tags are system-specific values used to identify a processing
resource that a Requester explicitly targets. System software discovers
and identifies TPH capabilities to determine the Steering Tag allocation
for each Function that supports TPH
[2] Steering Tags
Functions that intend to target a TLP towards a specific processing
resource such as a host processor or system cache hierarchy require
topological information of the target cache (e.g., which host cache).
Steering Tags are system-specific values that provide information about
the host or cache structure in the system cache hierarchy. These values
are used to associate processing elements within the platform with the
processing of Requests.
[3] Processing Hints
The Requester provides hints to the Root Complex or other targets about
the intended use of data and data structures by the host and/or device.
The hints are provided by the Requester, which has knowledge of upcoming
Request patterns, and which the Completer would not be able to deduce
autonomously (with good accuracy)

Steering Tags are system-specific values used to identify a processing
resource that a Requester explicitly targets. System software discovers
and identifies TPH capabilities to determine the Steering Tag allocation
for each Function that supports TPH.
This patch adds steering tag support for mlx5 based NICs by:
- Enabling the TPH functionality over PCI if both FW and OS support it.
- Managing steering tags and their matching steering indexes by
writing a ST to an ST index over the PCI configuration space.
- Exposing APIs to upper layers (e.g.,mlx5_ib) to allow usage of
the PCI TPH infrastructure.
Further details:
- Upon probing of a device, the feature will be enabled based
on both capability detection and OS support.
- It will retrieve the appropriate ST for a given CPU ID and memory
type using the pcie_tph_get_cpu_st() API.
- It will track available ST indices according to the configuration
space table size (expected to be 63 entries), reserving index 0 to
indicate non-TPH use.
- It will assign a free ST index with a ST using the
pcie_tph_set_st_entry() API.
- It will reuse the same index for identical (CPU ID + memory type)
combinations by maintaining a reference count per entry.
- It will expose APIs to upper layers (e.g., mlx5_ib) to allow usage of
the PCI TPH infrastructure.
- SF will use its parent PF stuff.
