1387 Vectored interrupt mode allowing faster dispatching of interrupts.
1388 The board support code needs to be written to take advantage of this
1389 mode. Compatibility code is included to allow the kernel to run on
1390 a CPU that does not support vectored interrupts. It's safe to
1391 say Y here.
