The functions __kmalloc_noprof(), kmalloc_large_noprof(), kmalloc_trace_noprof() and their _node variants are all internal to the implementations of kmalloc_noprof() and kmalloc_node_noprof() and are only declared in the "public" slab.h and exported so that those implementations can be static inline and distinguish the build-time constant size variants. The only other users for some of the internal functions are slub_kunit and fortify_kunit tests which make very short-lived allocations. Therefore we can stop wrapping them with the alloc_hooks() macro. Instead add a __ prefix to all of them and a comment documenting these as internal. Also rename __kmalloc_trace() to __kmalloc_cache() which is more descriptive - it is a variant of __kmalloc() where the exact kmalloc cache has been already determined. The usage in fortify_kunit can be removed completely, as the internal functions should be tested already through kmalloc() tests in the test variant that passes non-constant allocation size.
