bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
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.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
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 *".

5648de0b1f devlink: introduce a helper for netlink multicast send
Introduce a helper devlink_nl_notify_send() so each object notification
function does not have to call genlmsg_multicast_netns() with the same
arguments.

cddbff470e devlink: send notifications only if there are listeners

11280ddeae devlink: introduce __devl_is_registered() helper and use it instead of xa_get_mark()
Introduce __devl_is_registered() which does not assert on devlink
instance lock and use it in notifications which may be called
without devlink instance lock held.

53590934ba devlink: rename netlink callback to be aligned with the generated ones
All remaining doit and dumpit netlink callback functions are going to be
used by generated split ops. They expect certain name format. Rename the
callback to be aligned with generated names.

9473bc0119 devlink: convert linecard nested devlink to new rel infrastructure
Benefit from the newly introduced rel infrastructure, treat the linecard
nested devlink instances in the same way as port function instances.
Convert the code to use the rel infrastructure.

d0b7e990f7 devlink: move linecard struct into linecard.c
Instead of exposing linecard struct, expose a simple helper to get the
linecard index, which is all is needed outside linecard.c. Move the
linecard struct to linecard.c and keep it private similar to the rest of
the devlink objects.
