 `trace_resched_ipi_reg'

Hi Thomas,

It's probably a bug fix that unveils the link errors.

commit: 902f1bb88397dd6769c98b2177bbda134b3a1ef2 [40/43] x86/idt: Deinline setup functions

        git checkout 902f1bb88397dd6769c98b2177bbda134b3a1ef2
        # save the attached .config to linux build tree
        make ARCH=i386
