If you mean the warning from the subject then those do seem to be gone.
But if I'm completely honest I don't remember how I triggered them in
the first place :S There weren't there on every build for me.

The objtool warning is still here:

$ make PAHOLE=~/pahole O=build_allmodconfig/ -j 60 >/tmp/stdout 2>/tmp/stderr; \
    cat /tmp/stderr 

vmlinux.o: warning: objtool: ___ksymtab+bpf_dispatcher_xdp_func+0x0: data relocation to !ENDBR: bpf_dispatcher_xdp_func+0x0 
vmlinux.o: warning: objtool: bpf_dispatcher_xdp+0xa0: data relocation to !ENDBR: bpf_dispatcher_xdp_func+0x0
