git log calls it this:

commit 656bba306827a44ed73b3f93f75bb3147de17fae
Author: Len Brown <len.brown@...el.com>
Date:   Sun Aug 16 11:45:48 2015 -0400

    x86/smpboot: Remove APIC.wait_for_init_deassert and atomic init_deasserted

So you want to simply do this:

$ git revert 656bba306827a44ed73b3f93f75bb3147de17fae

build and test.

cheers,
