My wording is incorrect, should be like this:
The new system vector layout:
First, two special vector: spurious and error.
Second, we have SMP system vector defined first( these implicitly reply on CONFIG_X86_LOCAL_APIC),
Third, comes the CONFIG_X86_LOCAL_APIC dependent vector definition, but not necessary SMP dependent.( Among these stands out IRQ_WORK, which neither depends on SMP nor CONFIG_X86_LOCAL_APIC.)
Finally, comes the rest vector definition that not only depends on CONFIG_X86_LOCAL_APIC, but also others(like MCE, virtualization).
