Current `dma_read!`, `dma_write!` macros also use a custom
`addr_of!()`-based implementation for projecting pointers, which has
soundness issue as it relies on absence of `Deref` implementation on types.
It also has a soundness issue where it does not protect against unaligned
fields (when `#[repr(packed)]` is used) so it can generate misaligned
accesses.

This commit migrates them to use the general pointer projection
infrastructure, which handles these cases correctly.

As part of migration, the macro is updated to have an improved surface
syntax. The current macro have

    dma_read!(a.b.c[d].e.f)

to mean `a.b.c` is a DMA coherent allocation and it should project into it
with `[d].e.f` and do a read, which is confusing as it makes the indexing
operator integral to the macro (so it will break if you have an array of
`CoherentAllocation`, for example).

This also is problematic as we would like to generalize
`CoherentAllocation` from just slices to arbitrary types.

Make the macro expects `dma_read!(path.to.dma, .path.inside.dma)` as the
canonical syntax. The index operator is no longer special and is just one
type of projection (in additional to field projection). Similarly, make
`dma_write!(path.to.dma, .path.inside.dma, value)` become the canonical
syntax for writing.

Another issue of the current macro is that it is always fallible. This
makes sense with existing design of `CoherentAllocation`, but once we
support fixed size arrays with `CoherentAllocation`, it is desirable to
have the ability to perform infallible indexing as well, e.g. doing a `[0]`
index of `[Foo; 2]` is okay and can be checked at build-time, so forcing
falliblity is non-ideal. To capture this, the macro is changed to use
`[idx]` as infallible projection and `[idx]?` as fallible index projection
(those syntax are part of the general projection infra). A benefit of this
is that while individual indexing operation may fail, the overall
read/write operation is not fallible.

Add a sample module under samples/workqueue/stall_detector/ that
reproduces a workqueue stall caused by PF_WQ_WORKER misuse.  The
module queues two work items on the same per-CPU pool, then clears
PF_WQ_WORKER and sleeps in wait_event_idle(), hiding from the
concurrency manager and stalling the second work item indefinitely.

This is useful for testing the workqueue watchdog stall diagnostics.

Pull driver core updates from Danilo Krummrich:
 "Bus:

   - Ensure bus->match() is consistently called with the device lock
     held

   - Improve type safety of bus_find_device_by_acpi_dev()

  Devtmpfs:

   - Parse 'devtmpfs.mount=' boot parameter with kstrtoint() instead of
     simple_strtoul()

   - Avoid sparse warning by making devtmpfs_context_ops static

  IOMMU:

   - Do not register the qcom_smmu_tbu_driver in arm_smmu_device_probe()

  MAINTAINERS:

   - Add the new driver-core mailing list (driver-core@lists.linux.dev)
     to all relevant entries

   - Add missing tree location for "FIRMWARE LOADER (request_firmware)"

   - Add driver-model documentation to the "DRIVER CORE" entry

   - Add missing driver-core maintainers to the "AUXILIARY BUS" entry

  Misc:

   - Change return type of attribute_container_register() to void; it
     has always been infallible

   - Do not export sysfs_change_owner(), sysfs_file_change_owner() and
     device_change_owner()

   - Move devres_for_each_res() from the public devres header to

  Revocable:

   - Patches for the revocable synchronization primitive have been
     scheduled for v7.0-rc1, but have been reverted as they need some
     more refinement

  Rust:

   - Device:
      - Support dev_printk on all device types, not just the core Device
        struct; remove now-redundant .as_ref() calls in dev_* print
        calls

   - Devres:
      - Introduce an internal reference count in Devres<T> to avoid a
        deadlock condition in case of (indirect) nesting

   - DMA:
      - Allow drivers to tune the maximum DMA segment size via
        dma_set_max_seg_size()

   - I/O:
      - Introduce the concept of generic I/O backends to handle
        different kinds of device shared memory through a common
        interface.

        This enables higher-level concepts such as register
        abstractions, I/O slices, and field projections to be built
        generically on top.

        In a first step, introduce the Io, IoCapable<T>, and IoKnownSize
        trait hierarchy for sharing a common interface supporting offset
        validation and bound-checking logic between I/O backends.

      - Refactor MMIO to use the common I/O backend infrastructure

   - Misc:
      - Add __rust_helper annotations to C helpers for inlining into
        Rust code

      - Use "kernel vertical" style for imports

      - Replace kernel::c_str! with C string literals

      - Update ARef imports to use sync::aref

      - Use pin_init::zeroed() for struct auxiliary_device_id and
        debugfs file_operations initialization

      - Use LKMM atomic types in debugfs doc-tests

      - Various minor comment and documentation fixes

   - PCI:
      - Implement PCI configuration space accessors using the common I/O
        backend infrastructure

      - Document pci::Bar device endianness assumptions

   - SoC:
      - Abstractions for struct soc_device and struct soc_device_attribute

      - Sample driver for soc::Device"
