2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-1/+1
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook-1/+1
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 *". Signed-off-by: Kees Cook <kees@kernel.org>

2020-02-25drm/amd/display: System crashes when add_ptb_to_table() gets calledPeikang Zhang-6/+10
[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.

2019-06-22drm/amd/display: move vmid determination logic to a moduleDmytro Laktyushkin-0/+158
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.
