Pull driver core updates from Greg KH:
 "Here is the big set of driver core changes for 6.11-rc1.

  Lots of stuff in here, with not a huge diffstat, but apis are evolving
  which required lots of files to be touched. Highlights of the changes
  in here are:

   - platform remove callback api final fixups (Uwe took many releases
     to get here, finally!)

   - Rust bindings for basic firmware apis and initial driver-core
     interactions.

     It's not all that useful for a "write a whole driver in rust" type
     of thing, but the firmware bindings do help out the phy rust
     drivers, and the driver core bindings give a solid base on which
     others can start their work.

     There is still a long way to go here before we have a multitude of
     rust drivers being added, but it's a great first step.

   - driver core const api changes.

     This reached across all bus types, and there are some fix-ups for
     some not-common bus types that linux-next and 0-day testing shook
     out.

     This work is being done to help make the rust bindings more safe,
     as well as the C code, moving toward the end-goal of allowing us to
     put driver structures into read-only memory. We aren't there yet,
     but are getting closer.

   - minor devres cleanups and fixes found by code inspection

   - arch_topology minor changes

   - other minor driver core cleanups

  All of these have been in linux-next for a very long time with no
  reported problems"

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
     required after reset before config access (Kevin Xie)

   - Define PCIE_T_RRS_READY_MS for the generic 100ms required after
     reset before config access (probably should be unified with
     PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)

  Resource management:

   - Rename find_resource() to find_resource_space() to be more
     descriptive (Ilpo Järvinen)

   - Export find_resource_space() for use by PCI core, which needs to
     learn whether there is available space for a bridge window (Ilpo
     Järvinen)

   - Prevent double counting of resources so window size doesn't grow on
     each remove/rescan cycle (Ilpo Järvinen)

   - Relax bridge window sizing algorithm so a device doesn't break
     simply because it was removed and rescanned (Ilpo Järvinen)

   - Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in
     pci_register_host_bridge() (not acpi_pci_root_create()) so we can
     unify it with similar DT functionality (Vidya Sagar)

   - Extend use of DT "linux,pci-probe-only" property so it works
     per-host bridge as well as globally (Vidya Sagar)

   - Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT
     "linux,pci-probe-only" property in pci_preserve_config() (Vidya

     Stanner)

   - Add an always-managed pcim_request_region() for use instead of
     pci_request_region() and similar, which are sometimes managed
     depending on whether pcim_enable_device() has been called
     previously (Philipp Stanner)

   - Reimplement pcim_set_mwi() so it doesn't need to keep store MWI
     state (Philipp Stanner)

   - Add pcim_intx() for use instead of pci_intx(), which is sometimes
     managed depending on whether pcim_enable_device() has been called

  Virtualization:

   - Add an ACS quirk for Broadcom BCM5760X multi-function NIC; it
     prevents transactions between functions even though it doesn't
     advertise ACS, so the functions can be attached individually via
     VFIO (Ajit Khaparde)

  Peer-to-peer DMA:

   - Add a "pci=config_acs=" kernel command-line parameter to relax
     default ACS settings to enable additional peer-to-peer

     use MSI (Huacai Chen)

  Microchip AXI PolarFlare PCIe controller driver:

   - Move pcie-microchip-host.c to a new PLDA directory (Minda Chen)

The only managed mapping function currently is pcim_iomap() which doesn't
allow for mapping an area starting at a certain offset, which many drivers
want.

Add pcim_iomap_range() as an exported function.

The bit describing whether the PCI device is currently pinned is stored
in struct pci_devres. To clean up and simplify the PCI devres API, it's
better if this information is stored in struct pci_dev.

This will later permit simplifying pcim_enable_device().

Move the 'pinned' boolean bit to struct pci_dev.

Restructure bits in struct pci_dev so the pm / pme fields are next to
each other.

<title>driver core: have match() callback in struct bus_type take a const *</title>

<content type='text'>
In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *.  This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.

Because the match() callback is in all busses, all busses are modified
to handle this properly.  This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.

For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

<title>PCI: Revert the cfg_access_lock lockdep mechanism</title>

<id>c9d52fb313d3719d69a040f4ca78a3e2e95fba21</id>
<content type='text'>
While the experiment did reveal that there are additional places that are
missing the lock during secondary bus reset, one of the places that needs
to take cfg_access_lock (pci_bus_lock()) is not prepared for lockdep
annotation.

Specifically, pci_bus_lock() takes pci_dev_lock() recursively and is
currently dependent on the fact that the device_lock() is marked
lockdep_set_novalidate_class(&amp;dev-&gt;mutex). Otherwise, without that
annotation, pci_bus_lock() would need to use something like a new
pci_dev_lock_nested() helper, a scheme to track a PCI device's depth in the
topology, and a hope that the depth of a PCI tree never exceeds the max
value for a lockdep subclass.

The alternative to ripping out the lockdep coverage would be to deploy a
dynamic lock key for every PCI device. Unfortunately, there is evidence
that increasing the number of keys that lockdep needs to track to be
per-PCI-device is prohibitively expensive for something like the
cfg_access_lock.

The main motivation for adding the annotation in the first place was to
catch unlocked secondary bus resets, not necessarily catch lock ordering
problems between cfg_access_lock and other locks. Solve that narrower
problem with follow-on patches, and just due to targeted revert for now.

<id>4eed3dd7116814c82630b0f1b0f73fa96707134f</id>
<content type='text'>
To make it simpler to declare resource constraint alignf callbacks, add
typedef for it and document it.

- Clear bridge Secondary Status errors after enumeration since enumeration
  causes many errors (Vidya Sagar)

- Wait for Link Training==0 before starting Link retrain to avoid a race;
  this was done previously but broken by a faulty merge (Ilpo Järvinen)

- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific about what
  "LEGACY" means (Damien Le Moal)

- Update return types of pci_find_capability() stubs to match the extern
  declarations for the actual implementations (Bjorn Helgaas)

- Drop unnecessary pci_enable_device_io() from pata_cs5520 (Heiner
  Kallweit)

- Drop unused pci_enable_device_io() (Heiner Kallweit)

- On 2016 and newer BIOSes, skip early E820 check for ECAM regions
  described in ACPI MCFG; there's no spec requirement for E820
  reservations, and some machines don't provide them (Bjorn Helgaas)

- If devices were disconnected while suspended, don't wait for them when
  resuming (Ilpo Järvinen)
