<title>Convert 'alloc_obj' family to use the new default GFP_KERNEL argument</title>

<id>bf4afc53b77aeaa48b5409da5c8da6bb4eff7f43</id>
<content type='text'>
This was done entirely with mindless brute force, using

    git grep -l '\&lt;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.

<title>treewide: Replace kmalloc with kmalloc_obj for non-scalar types</title>

<id>69050f8d6d075dc01af7a5f2f550a8067510366f</id>
<content type='text'>
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 *".

<title>drm/amd/display/dc/irq: Remove duplications of hpd_ack function from IRQ</title>

<id>7e340d3ceacf75e3e088fcc3dd4f8729d6c079c3</id>
<content type='text'>
The major of dcn and dce irqs share a copy-pasted collection
of copy-pasted function, which is: hpd_ack.

This patch removes the multiple copy-pasted by moving them to
the irq_service.c and make the irq_service's
calls the functions implemented by the irq_service.c
instead.

The hpd_ack function is replaced by hpd0_ack and hpd1_ack, the
required constants are also added.

The changes were not tested on actual hardware. I am only able
to verify that the changes keep the code compileable and do my
best to look repeatedly if I am not actually changing any code.
