The PIT code has been changed in order to suppport GENERIC_CLOCKEVENTS. The priority of the PIT clocksource has been decreased in favor of the DMA timer. pit_cycles_per_jiffy become a constant (PIT_CYCLES_PER_JIFFY) because it is known at compile time and does not change afterwards.

processor vectors at the base of RAM and then the start of the

kernel. On some platforms some RAM is reserved for boot loaders

a system with the RAM based at address 0, and leaving enough room

for the theoretical maximum number of 256 vectors.
