- Fix a secondary CPUs enumeration regression caused by creative
MADT APIC table entries on certain systems.
- Fix a race in the NOP-patcher that can spuriously trigger crashes
on bootup.
- Fix a bootup failure regression caused by the parallel bringup
code, caused by firmware inconsistency between the APIC
initialization states of the boot and secondary CPUs, on certain
systems.
