Memory allocation only happens in the self test, just as random numbers are only used there. So move the inclusion of slab.h inside the CONFIG_TEST_LIST_SORT. We don't need module.h and all of the stuff it carries with it, so replace with export.h and compiler.h. Unfortunately, the ARRAY_SIZE macro from kernel.h requires the user to ensure bug.h is also included (for BUILD_BUG_ON_ZERO, used by __must_be_array). We used to get that through some maze of nested includes, but just include it explicitly. linux/string.h is then only included implicitly through kernel.h->printk.h->dynamic_debug.h, but only if !CONFIG_DYNAMIC_DEBUG, so just include it explicitly (for memset). objdump -d says the generated code is the same, and wc -l says that lib/.list_sort.o.cmd went from 579 to 165 lines.
