Add support for DMABUF MR registrations with Data-direct device.

Upon userspace calling to register a DMABUF MR with the data direct bit
set, the below algorithm will be followed.

1) Obtain a pinned DMABUF umem from the IB core using the user input
parameters (FD, offset, length) and the DMA PF device.  The DMA PF
device is needed to allow the IOMMU to enable the DMA PF to access the
user buffer over PCI.

2) Create a KSM MKEY by setting its entries according to the user buffer
VA to IOVA mapping, with the MKEY being the data direct device-crossed
MKEY. This KSM MKEY is umrable and will be used as part of the MR cache.
The PD for creating it is the internal device 'data direct' kernel one.

3) Create a crossing MKEY that points to the KSM MKEY using the crossing
access mode.

4) Manage the KSM MKEY by adding it to a list of 'data direct' MKEYs
managed on the mlx5_ib device.

5) Return the crossing MKEY to the user, created with its supplied PD.

Upon DMA PF unbind flow, the driver will revoke the KSM entries.
The final deregistration will occur under the hood once the application
deregisters its MKEY.

Notes:
- This version supports only the PINNED UMEM mode, so there is no
  dependency on ODP.
- The IOVA supplied by the application must be system page aligned due to
  HW translations of KSM.
- The crossing MKEY will not be umrable or part of the MR cache, as we
  cannot change its crossed (i.e. KSM) MKEY over UMR.

Introduce the 'data direct' driver for a ConnectX-8 Data Direct device.

The 'data direct' driver functions as the affiliated DMA device for one
or more capable mlx5_ib devices. This DMA device, as the name suggests,
is used exclusively for DMA operations. It can be considered a DMA engine
managed by a PF/VF, lacking network capabilities and having minimal overall
capabilities.

Consequently, the DMA NIC PF will not be exposed to or directly used by
software applications. The driver will not have any direct interface or
interaction with the firmware (no command interface, no capabilities,
etc.). It will operate solely over PCI to enable its DMA functionality.

Registration and un-registration of the driver are handled as part of
the mlx5_ib initialization and exit processes, as the mlx5_ib devices
will effectively be its clients.

The driver will serve as the DMA device for accessing another PCI device
to achieve optimal performance (both on the same NUMA node, P2P access,
etc.).

Upon probing, it will read its VUID over PCI to handle mlx5_ib device
registrations with the same VUID.

Upon removal, it will notify its clients to allow them to clean up the
resources that were mmaped with its DMA device.

From Yishai,

Overview
--------
This patch series aims to enable multi-path DMA support, allowing an
mlx5 RDMA device to issue DMA commands through multiple paths. This
feature is critical for improving performance and reaching line rate
in certain environments where issuing PCI transactions over one path
may be significantly faster than over another. These differences can
arise from various PCI generations in the system or the specific system
topology.

To achieve this functionality, we introduced a data direct DMA device
that can serve the RDMA device by issuing DMA transactions on its
behalf.

The main key features and changes are described below.

Multi-Path Discovery
--------------------
API Implementation:
 * Introduced an API to discover multiple paths for a given mlx5 RDMA
   device.
IOCTL Command:
 * Added a new IOCTL command, MLX5_IB_METHOD_GET_DATA_DIRECT_SYSFS_PATH, to
   the DEVICE object. When an affiliated Data-Direct/DMA device is present,
   its sysfs path is returned.

Feature Activation by mlx5 RDMA Application
-------------------------------------------
UVERBS Extension:
 * Extended UVERBS_METHOD_REG_DMABUF_MR over UVERBS_OBJECT_MR to include
   mlx5 extended flags.
Access Flag:
 * Introduced the MLX5_IB_UAPI_REG_DMABUF_ACCESS_DATA_DIRECT flag, allowing
   applications to request the use of the affiliated DMA device for DMABUF
   registration.

Data-Direct/DMA Device
----------------------
New Driver:
 * Introduced a new driver to manage the new DMA PF device ID (0x2100).
   Its registration/un-registration is handled as part of the mlx5_ib init/exit
   flows, with mlx5 IB devices as its clients.
Functionality:
 * The driver does not interface directly with the firmware (no command interface,
   no caps, etc.) but works over PCI to activate its DMA functionality. It serves
   as the DMA device for efficiently accessing other PCI devices (e.g., GPU PF) and
   reads its VUID over PCI to handle NICs registrations with the same VUID.

mlx5 IB RDMA Device
---------------------------
VUID Query:
 * Reads its affiliated DMA PF VUID via the QUERY_VUID command with the data_direct
   bit set.
Driver Registration:
 * Registers with the DMA PF driver to be notified upon bind/unbind.
Application Request Handling:
 * Uses the DMA PF device upon application request as described above.

DMABUF over Umem
----------------
Introduced an option to obtain a DMABUF UMEM using a different DMA
device instead of the IB device, allowing the device to register over
IOMMU with the expected DMA device for a given buffer registration.

Further details are provided in the commit logs of the patches in this series.

Use strict parsing validation for set commands, and liberal
validation for get commands. Additionally, remove all usage of
nlmsg_parse_depricate().

Strict parsing validation fails when encountering unrecognized
attributes in the Netlink message, while liberal parsing
validation ignores them.

In 57d7a8fd904c ("rdma: Add an option to display driver-specific QPs in the rdma tool")
in iproute2, the attribute RDMA_NLDEV_ATTR_DRIVER_DETAILS
was added. This cause backwards compatibility issues when using
the rdma tool with the new attribute and an older kernel which does
recognize this attribute.
In this case, the command "rdma stat show mr" would fail, because the
new rdma tool would fill the netlink message with the new attribute and
the older kernel would fail as it used strict parsing and did not
recognize the new attribute.

In general, strict validation is appropriate for set commands as they
modify the system, while liberal validation is suitable for get
commands which only query system information.

Replace all uses of nlmsg_parse_deprecated() with __nlmsg_parse(),
using the NL_VALIDATE_LIBERAL flag.
The nlmsg_parse_deprecated() function internally calls
__nlmsg_parse() with the NL_VALIDATE_LIBERAL flag, but its name
is confusing.

The kernel sleep profile is no longer working due to a recursive locking

Booting with the 'profile=sleep' kernel command line option added or
executing

  # echo -n sleep > /sys/kernel/profiling

after boot causes the system to lock up.

Lockdep reports

However, since nobody noticed this regression for more than two years,
let's remove 'profile=sleep' support based on the assumption that nobody
needs this functionality.

Pull x86 fixes from Thomas Gleixner:

 - Prevent a deadlock on cpu_hotplug_lock in the aperf/mperf driver.

   A recent change in the ACPI code which consolidated code pathes moved
   the invocation of init_freq_invariance_cppc() to be moved to a CPU
   hotplug handler. The first invocation on AMD CPUs ends up enabling a
   static branch which dead locks because the static branch enable tries
   to acquire cpu_hotplug_lock but that lock is already held write by
   the hotplug machinery.

   Use static_branch_enable_cpuslocked() instead and take the hotplug
   lock read for the Intel code path which is invoked from the
   architecture code outside of the CPU hotplug operations.

 - Fix the number of reserved bits in the sev_config structure bit field
   so that the bitfield does not exceed 64 bit.

 - Add missing Zen5 model numbers

 - Fix the alignment assumptions of pti_clone_pgtable() and
   clone_entry_text() on 32-bit:

   The code assumes PMD aligned code sections, but on 32-bit the kernel
   entry text is not PMD aligned. So depending on the code size and
   location, which is configuration and compiler dependent, entry text
   can cross a PMD boundary. As the start is not PMD aligned adding PMD
   size to the start address is larger than the end address which
   results in partially mapped entry code for user space. That causes
   endless recursion on the first entry from userspace (usually #PF).

   Cure this by aligning the start address in the addition so it ends up
   at the next PMD start address.

   clone_entry_text() enforces PMD mapping, but on 32-bit the tail might
   eventually be PTE mapped, which causes a map fail because the PMD for
   the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for
   the clone() invocation which resolves to PTE on 32-bit and PMD on
   64-bit.

 - Zero the 8-byte case for get_user() on range check failure on 32-bit

   The recend consolidation of the 8-byte get_user() case broke the
   zeroing in the failure case again. Establish it by clearing ECX
   before the range check and not afterwards as that obvioulsy can't be
   reached when the range check fails

Pull timer fixes from Thomas Gleixner:
 "Two fixes for the timer/clocksource code:

   - The recent fix to make the take over of the broadcast timer more
     reliable retrieves a per CPU pointer in preemptible context.

     This went unnoticed in testing as some compilers hoist the access
     into the non-preemotible section where the pointer is actually
     used, but obviously compilers can rightfully invoke it where the
     code put it.

     Move it into the non-preemptible section right to the actual usage
     side to cure it.

   - The clocksource watchdog is supposed to emit a warning when the
     retry count is greater than one and the number of retries reaches
     the limit.

     The condition is backwards and warns always when the count is
     greater than one. Fixup the condition to prevent spamming dmesg"

Pull scheduler fixes from Thomas Gleixner:

 - When stime is larger than rtime due to accounting imprecision, then
   utime = rtime - stime becomes negative. As this is unsigned math, the
   result becomes a huge positive number.

   Cure it by resetting stime to rtime in that case, so utime becomes 0.

 - Restore consistent state when sched_cpu_deactivate() fails.

   When offlining a CPU fails in sched_cpu_deactivate() after the SMT
   present counter has been decremented, then the function aborts but
   fails to increment the SMT present counter and leaves it imbalanced.
   Consecutive operations cause it to underflow. Add the missing fixup
   for the error path.

   For SMT accounting the runqueue needs to marked online again in the
   error exit path to restore consistent state.

 "If an output section’s name is the same as the input section’s name
  and is representable as a C identifier, then the linker will
  automatically PROVIDE two symbols: __start_SECNAME and __stop_SECNAME,
  where SECNAME is the name of the section. These indicate the start
  address and end address of the output section respectively"

to just automatically define the symbol names for the bounds of the
runtime constant arrays.

It turns out that this isn't actually something we can rely on, with old
linkers not generating these automatic symbols.  It looks to have been
introduced in binutils-2.29 back in 2017, and we still support building
with versions all the way back to binutils-2.25 (from 2015).

And yes, Oleg actually seems to be using such ancient versions of
binutils.

So instead of depending on the implicit symbols from "section names
match and are representable C identifiers", just do this all manually.
It's not like it causes us any extra pain, we already have to do that
for all the other sections that we use that often have special
characters in them.

Pull thermal control fixes from Rafael Wysocki:
 "These fix a few issues related to the MSI IRQs management in the
  int340x thermal driver, fix a thermal core issue that may lead to
  missing trip point crossing events and update the thermal core
  documentation.

  Specifics:

   - Fix MSI error path cleanup in int340x, allow it to work with a
     subset of thermal MSI IRQs if some of them are not working and make
     it free all MSI IRQs on module exit (Srinivas Pandruvada)

Pull kvm updates from Paolo Bonzini:
 "The bulk of the changes here is a largish change to guest_memfd,
  delaying the clearing and encryption of guest-private pages until they
  are actually added to guest page tables. This started as "let's make
  it impossible to misuse the API" for SEV-SNP; but then it ballooned a
  bit.

  The new logic is generally simpler and more ready for hugepage support
  in guest_memfd.

  Summary:

   - fix latent bug in how usage of large pages is determined for
     confidential VMs

   - fix "underline too short" in docs

   - eliminate log spam from limited APIC timer periods

   - disallow pre-faulting of memory before SEV-SNP VMs are initialized

   - delay clearing and encrypting private memory until it is added to
     guest page tables

   - this change also enables another small cleanup: the checks in
     SNP_LAUNCH_UPDATE that limit it to non-populated, private pages can
     now be moved in the common kvm_gmem_populate() function

   - fix compilation error that the RISC-V merge introduced in selftests"
