[PATCH v3 13/13] bpf: remove CONFIG_BPF_JIT dependency on CONFIG_MODULES of

From: Mike Rapoport

From: "Mike Rapoport (IBM)" <rppt@xxxxxxxxxx>

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.

BPF programs are normally handled by a BPF interpreter. This option
allows the kernel to generate native code when a program is loaded
