It was originally in x86/urgent, but was deemed wrong so got zapped. But in the meantime, x86/urgent had been merged into x86/apic to resolve a conflict. I didn't notice the merge so didn't zap it from x86/apic and it managed to make it up with the x86/apic material. The reverted commit is known to cause some KASAN problems.
