This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Copy TPMI’s OOBMSM platform info into a common area within VSEC private
data via intel_vsec_set_mapping(). This enables other Intel VSEC features
to access the CPU mapping without additional queries.

Additionally, designate the TPMI driver as a supplier for the Telemetry
driver, ensuring it can obtain the necessary platform information for
future feature extensions.

Add functions, intel_vsec_set/get_mapping(), to set and retrieve the
OOBMSM-to-CPU mapping data in the private data of the parent Intel VSEC
driver. With this mapping information available, other Intel VSEC features
on the same OOBMSM device can easily access and use the mapping data,
allowing each of the OOBMSM features to map to the CPUs they provides data
for.

Some VSEC features depend on the presence of supplier features that may not
always be present. To prevent unnecessary retries and device linking during
initialization, introduce logic to skip attempts to link consumers to
missing suppliers.

New Intel VSEC features will have dependencies on other features, requiring
certain supplier drivers to be probed before their consumers. To enforce
this dependency ordering, introduce device links using device_link_add(),
ensuring that suppliers are fully registered before consumers are probed.

- Add device link tracking by storing supplier devices and tracking their
  state.
- Implement intel_vsec_link_devices() to establish links between suppliers
  and consumers based on feature dependencies.
- Add get_consumer_dependencies() to retrieve supplier-consumer
  relationships.
- Modify feature registration logic:
  * Consumers now check that all required suppliers are registered before
    being initialized.
  * suppliers_ready() verifies that all required supplier devices are
    available.
- Prevent potential null consumer name issue in sysfs:
  - Use dev_set_name() when creating auxiliary devices to ensure a
    unique, non-null consumer name.
- Update intel_vsec_pci_probe() to loop up to the number of possible
  features or when all devices are registered, whichever comes first.
- Introduce VSEC_CAP_UNUSED to prevent sub-features (registered via
  exported APIs) from being mistakenly linked.
