This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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

platform/x86: intel: Use -y instead of -objs in Makefile

2025-02-24T15:15:06+00:00

The `objs` suffix is reserved for user-space tools. Use the `y` suffix instead, which is usually used for kernel drivers.

platform/x86/intel/ifs: Fix SBAF title underline length

2024-08-24T13:00:29+00:00

In commit # 0a3e4e94d137 ("platform/x86/intel/ifs: Add SBAF test image loading support"), the documentation for "Structural Based Functional Test at Field (SBAF)" had an incomplete underline. This resulted in the following build warning: Documentation/arch/x86/ifs:2: drivers/platform/x86/intel/ifs/ifs.h:131: WARNING: Title underline too short. Fix it by extending the dotted lines to match the length of the title.
