Hi,

For some reason, the attached .config file generates over 350 objtool warnings.
There are all "unreachable instruction" warnings.

Here is a small sample:

mm/page-writeback.o: warning: objtool: __set_page_dirty_nobuffers()+0x25b: unreachable instruction
kernel/sched/fair.o: warning: objtool: load_balance()+0x54c: unreachable instruction
kernel/power/process.o: warning: objtool: freeze_kernel_threads()+0x115: unreachable instruction
mm/readahead.o: warning: objtool: read_cache_pages_invalidate_page()+0x1b5: unreachable instruction
kernel/power/suspend.o: warning: objtool: suspend_devices_and_enter()+0x101f: unreachable instruction
kernel/sched/rt.o: warning: objtool: dequeue_top_rt_rq()+0x67: unreachable instruction
