platform/x86/amd: pmc: Add Thinkpad L14 Gen3 to quirk_s2idle_bug

2026-03-27T11:31:15Z

This platform is a similar vintage of platforms that had a BIOS bug leading to a 10s delay at resume from s0i3. Add a quirk for it.

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51Z

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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/amd: Use scope-based cleanup for wbrf_record()

2026-01-26T13:46:32Z

Simplify resource management in wbrf_record() by using the scope-based cleanup helper __free(). This ensures that the tmp and obj are automatically freed when they go out of scope, eliminating the need for explicit error handling labels and manual freeing.
