Subject: linux-next: build warning after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

vmlinux.o: warning: objtool: mce_setup()+0x22: call to memset() leaves .noinstr.text section
vmlinux.o: warning: objtool: do_machine_check()+0x51: call to mce_gather_info() leaves .noinstr.text section
vmlinux.o: warning: objtool: rcu_dynticks_eqs_enter()+0x0: call to rcu_dynticks_task_trace_enter() leaves .noinstr.text section
vmlinux.o: warning: objtool: rcu_dynticks_eqs_exit()+0xe: call to rcu_dynticks_task_trace_exit() leaves .noinstr.text section
vmlinux.o: warning: objtool: rcu_nmi_enter()+0x36: call to __kasan_check_read() leaves .noinstr.text section

I don't know what produced these warnings.
