Today's linux-next gives these objtool warnings:

arch/x86/entry/vdso/vma.o: warning: objtool: vdso_fault()+0x201: unreachable instruction

drivers/ide/ide-tape.o: warning: objtool: idetape_chrdev_release()+0x109: unreachable instruction

drivers/media/i2c/ir-kbd-i2c.o: warning: objtool: ir_probe()+0xdaa: unreachable instruction

kernel/kcov.o: warning: objtool: __sanitizer_cov_trace_pc()+0x89: call to __ubsan_handle_load_invalid_value() with UACCESS enabled


all in (4) separate builds (.configs).
Do you want all 4 randconfig files?

cheers.
