4.9-stable review patch. If anyone has any objections, please let me know.

commit 05ab1d8a4b36ee912b7087c6da127439ed0a903e upstream.
This backport is incorrect. The part that updated __startup_64() in arch/x86/kernel/head64.c was dropped, presumably because that function doesn't exist in 4.9. However that seems to be an essential of the fix. In 4.9 the startup_64 routine in arch/x86/kernel/head_64.S would need to be changed instead.
I also found that this introduces new boot-time warnings on some systems if CONFIG_DEBUG_WX is enabled.
So, unless someone provides fixes for those issues, I think this should be reverted for the 4.9 branch.
Thanks for the catch, I'm fine with the revert for now.
I've queued the revert, thank you.
