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).
