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 *".

The driver stores HW timestamping configuration and can technically
report it. Add callback to do it.

The driver stores new HW timestamping configuration values
unconditionally and may create inconsistency with what is actually
configured in case of error. Improve the logic to store new values only
once everything is configured.

PHY devices has hwtstamp callback which actually performs set operation.
Rename it to better reflect the action.

The PTP_PEROUT_REQUEST2 ioctl has gained support for flags specifying
specific output behavior including PTP_PEROUT_ONE_SHOT,
PTP_PEROUT_DUTY_CYCLE, PTP_PEROUT_PHASE.
Driver authors are notorious for not checking the flags of the request.
This results in misinterpreting the request, generating an output signal
that does not match the requested value. It is anticipated that even more
flags will be added in the future, resulting in even more broken requests.
Expecting these issues to be caught during review or playing whack-a-mole
after the fact is not a great solution.
Instead, introduce the supported_perout_flags field in the ptp_clock_info
structure. Update the core character device logic to explicitly reject any
request which has a flag not on this list.
This ensures that drivers must 'opt in' to the flags they support. Drivers
which don't set the .supported_perout_flags field will not need to check
that unsupported flags aren't passed, as the core takes care of this.
Update the drivers which do support flags to set this new field.
Note the following driver files set n_per_out to a non-zero value but did
not check the flags at all:
• drivers/ptp/ptp_clockmatrix.c
• drivers/ptp/ptp_idt82p33.c
• drivers/ptp/ptp_fc3.c
• drivers/net/ethernet/ti/am65-cpts.c
