Merge branch 'slab/for-6.2/alloc_size' into slab/for-next
Two patches from Kees Cook [1]:
These patches work around a deficiency in GCC (>=11) and Clang (<16)
where the __alloc_size attribute does not apply to inlines.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96503
This manifests as reduced overflow detection coverage for many allocation
sites under CONFIG_FORTIFY_SOURCE=y, where the allocation size was not
actually being propagated to __builtin_dynamic_object_size().
