Presume that kernel is compiled for x86_64 with gcc version 13.3.0:

  make allmodconfig
  make KCFLAGS="-fno-inline-small-functions -fno-inline-functions-called-once"

This results some objtool warnings:

  vmlinux.o: warning: objtool: rseq_update_cpu_node_id+0x14c: call to rseq_kernel_fields() with UACCESS enabled
  vmlinux.o: warning: objtool: rseq_reset_rseq_cpu_node_id+0xef: call to rseq_kernel_fields() with UACCESS enabled
