Daniel Borkmann 6c7c8badfe bpf, x86: Generalize and extend bpf_arch_text_poke for direct jumps 
[upstream commit 4b3da77b72ad6b3c48c6fe4a395ace7db39a12c5]

Add BPF_MOD_{NOP_TO_JUMP,JUMP_TO_JUMP,JUMP_TO_NOP} patching for x86
JIT in order to be able to patch direct jumps or nop them out. We need
this facility in order to patch tail call jumps and in later work also
BPF static keys.
