on x86_64, with an older gcc:  gcc (SUSE Linux) 4.8.5

some builds (3) say:
kernel/bpf/core.o: warning: objtool: ___bpf_prog_run()+0xb2: sibling call from callable instruction with modified stack frame
(see core.o.r6235)

and one build says:
kernel/bpf/core.o: warning: objtool: ___bpf_prog_run()+0x2a: can't find switch jump table
(see core.o.r6238)
