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 *".

Replace the manual string copying and parsing logic with a call to
simple_strtoull() to simplify and improve qat_uclo_parse_num().
Ensure that the parsed number does not exceed UINT_MAX, and add an
approximate upper-bound check (no more than 19 digits) to guard against
overflow.

Update the names of the defines for PCI IDs to follow the standard
naming convention `PCI_DEVICE_ID_<DEVICE NAME>`.
Also drop the unnecessary inner comma from the pci_device_id tables that
use these definitions.
This does not introduce any functional change.

The BITS_IN_DWORD() macro, which represents the number of bits in the
registers accessed by the firmware loader, is currently defined as 32.
For consistency and readability, replace this macro with the existing
BITS_PER_TYPE() macro, which serves the same purpose.
This does not introduce any functional change.

The memory requested to hold the image data for authentication will
never exceed `ICP_QAT_CSS_RSA4K_MAX_IMAGE_LEN`. Therefore, we can
simplify the allocation by always requesting the maximum size needed for
any image.
Also introduce the following checks:
* Ensure the allocated memory is 8-byte aligned to meet the
requirements of the authentication firmware.
* Prevent overflow when constructing the authentication descriptor.

Add support for 420xx devices by including a new device driver that
supports such devices, updates to the firmware loader and capabilities.
Compared to 4xxx devices, 420xx devices have more acceleration engines
(16 service engines and 1 admin) and support the wireless cipher
algorithms ZUC and Snow 3G.
