Ingo and I have some minor disagreements about how the NMI on UP patch
should be done. My current version is in It is Ingo's
patch plus my reinstatement of bits that he removed but that I believe
are required, especially for SMP boxes. Moving clear_local_APIC() from
setup_local_APIC() back to connect_bsp_APIC() fixes the lock up in
Calibrating delay loop, this is included in my patch.
