From: "Mike Rapoport (IBM)" <rppt@kernel.org> BPF just-in-time compiler depended on CONFIG_MODULES because it used module_alloc() to allocate memory for the generated code. Since code allocations are now implemented with execmem, drop dependency of CONFIG_BPF_JIT on CONFIG_MODULES and make it select CONFIG_EXECMEM.
