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 *".

0062972b9d drm/amd/display: System crashes when add_ptb_to_table() gets called
[Why]
Unused VMIDs were not evicted correctly

[How]
1. evict_vmids() logic was fixed;
2. Added boundary check for add_ptb_to_table() and
   clear_entry_from_vmid_table() to avoid crash caused by array out of
   boundary;
3. For mod_vmid_get_for_ptb(), vimd is changed from unsigned to signed
   due to vimd is signed.

bda9afdacf drm/amd/display: move vmid determination logic to a module
Currently vmid is decided internally inside dc. With the introduction
of new asics we are required to coordinate vmid use with external
components.

This change converts vmid logic to a DAL module allowing vmid to be
passed in as a parameter to DC.
